A problem with flapping 1G optical SFP interfaces. Two different vendors tested (not Mikrotik). There is no issue when using 10G interfaces.

Disable auto negotiation and 1Gb SFP will work correctly.

https://wiki.mikrotik.com/wiki/MikroTik ... ansceivers
For MikroTik devices with SFP+ interface that support both 10G and 1G link rate following settings are needed to be set on both linked devices for required interfaces. These settings only relate when optical SFP transceivers are used. In order to get them working in 1G link rate, use the following configuration:
  • auto-negotiation disabled
  • port speed 1G
  • FD
Devices which SFP+ ports support 1G links:
  • RB4011 series - SFP+1 interface can be used in 1G mode if required.

I haven't tested between two RB4011s, but between RB2011 and RB4011 the flapping will stop if you disable autoneg on both the RB4011 and RB2011, not just the RB4011.

I'm pretty interested in this device, since it seems a good successor to the already pretty cool RB2011 series, which my internet provider is kinda recommending.

However I'm very confused about SFP(+) and the compatibility of those modules to this specific device. My provider requires the following specs: 10 km, TX1310 / RX1490nm

I don't seem to find something with those specs from Mikrotik and I'm not sure if some third party interface like the Flexoptix 1G SFP Wideband BiDi LX LC Simplex will be supported. Has anybody any recommendations on this? People in this thread seem to already have problems with the SFP module.

Sorry if it's a stupid question, but I have absolutely no clue about SFP and what all those numbers mean exactly. This seems way more complicated than necessary.

No wonder - it's beefy yet passive. CCR1009-PC can give you actual burns if you touch heatsink while it's powered on. Even if idling (there's actually not that huge difference in thermals between idle and stress)

This SFP mess is really annoying! Why can't it just work? If I connect cheap TP-Link switch to Cisco, auto negotiation on SFP works. Same with even cheaper Realtek cards, various Dell servers and other equipment. But no, for Mikrotik, you have to manually set the speeds on both ends.
Where's the problem? Some hardware issue on used chipset/cpu on Mikrotik side? Bad implementation? Incompatibility of some SFPs? Or just laziness to do it right?
And "Just disable auto negotiation and set rate manually" is NOT the solution. What if you can't set other side of the link? Often any administrative change of parameters of upstream link costs extra money. This needs to be either fixed or have warning written on all Mikrotik product pages that SFP port doesn't support auto negotiation. It's 2018 and you expect these things to just work. If there was a list of verified SFPs that do work, that would be fine. But so far it seems auto negotiation on SFP port just doesn't work, no matter what SFP or DAC you use.
Fix it or say clearly it's not supported and will never work!

I have some machines that don't allow disabling auto negotiation on onboard NICs and they improperly negotiate link with S+RJ10 to 10G even though servers have gigabit link. With disabled autonegotiation link doesn't establish at all.

Yes those are shitty machines - deal with it. What to expect, if they weren't I could probably afford Cisco in the first place.

Personally I am replacing a rb2011uias-2hnd-in, I never used LCD, USB or speaker, so this is not a big deal for me with the cpu power available. The upgrade on the wireless side is much more a thing for me.
Ordered today the wifi version, found exactly one distributor who has like 40 on stock according their website so seems they are finally in stock. Not sure if I could post which, but it’s one from Latvia with inernational shipping that was in the first results when doing a google search after the full device name.

I don't think it's "secret" anymore. More and more distributors have wifi version available. Eg. CDR in Poland already has them. I randomly checked few days ago. Probably plenty of distributors already have them.

is the 20/24/80/160mhz setting working? tried to use it (default channels or not, various countries or debug, various combinations of main channel and extensions) but wireless adapter (intel ac7260) stopped to see it. on 20/40/80 it works normally (even in the meantime i did a complete reset on 4011, because playing with these various settings made the 5ghz interface inoperable :) )

Hi there,

Few weeks ago, I got my own RB4011 with wireless version.
Let me share few points about this device:
1. The CPU has very well performance, I tested performance with pure NAT, and it only got about 27~30% CPU usage with 1Gb full speed.
螢幕快照 2018-11-26 下午2.48.24.png
2. Tested performance with my iPhone Xr, using iPerf to test can got about 380~420Mb/s, and sometimes can got over 500Mb/s when iPhone sending packet during test.
3. The case is close to full-metal design (I know the bottom half case is plastic), the CPU is directly using thermal pad to touch metal case to cooling. The CPU temperature is not over 45C since started using.

In summary, this one is a beast, and the price is very well, too. Now decided to use as backup router in my office if main is down (the main is SRX240)

(P.S 160MHz in 5G WIFI is not working on many normal clients, need to set up to 80MHz only.)

some tests made with RB4011iGS+5HacQ2HnD and CCR1009-7G-1C-1S+, using bandwidth server, default mtu.
1. i managed to use a 3m direct attach cable between the two sfp+ ports; 10gbps link is negotiated, but is somewhat asymmetrical:
*RB client, CCR server
send, udp - 1650mbps
send, tcp - 740 mbps
receive, udp - 1500kbps
receive, tcp - 500kbps
*CCR client, RB server
send, udp - 2mbps
send, tcp - 500kbps
receive, udp - 1550mbps
receive, tcp - 740mbps
2. after this, i used S+RJ10 and a 2m cat6 patchcord
*RB client, CCR server
send, udp - 1620mbps
send, tcp - 770mbps
receive, udp - 2048mbps
receive, tcp - 900mbps
*CCR client, RB server
send, udp - 2048mbps
send, tcp - 900mbps
receive, udp - 1550mbps
receive, tcp - 740mbps
These 2gbps values are completely stable, not even a spike. cpu un rb is max 25%, on ccr 12%
I'm asking myself... is RB SFP+ link to cpu limited to 2gbps, like these two switches inside, by pcie 1.0 x1?
my first verdict: could be a router offered by providers for future implementations of 2gbps pppoe. or usable as AP, with some smaller wired clients, maybe one with lacp.

Just to be sure, during these tests, you didn't use bandwidth server or testing tools on the Routerboards themselves correct? Only using clients (PC's) that are in front and behind the routers mentioned? If not, and your results seem to suggest this, you are only testing the CPU's in the Routerboards in how well they can generate traffic, not how much traffic they can handle while it's running through the boards, like in a real-world scenario.

The built-in testing tools are only intended to be used to test line bandwidth from one routerboard to another, if you have above a few hundred Mbit's of bandwidth, other factors become the limiting factor and they are useless.

this is what i intended to do. ccr will do better, for sure, but i was intrigued about that fixed line on 2gbps. again, 2.5gbps = pcie 1.0 x.1
i'll do some more tests these days, in a live 10gbps enviroment

Sorry, but I don't think you quite understand. What you have tested is CPU performance, not bandwidth. And in that regard, the RB4011 would actually preform better then a CCR because of higher single threaded performance (The newest newest beta version introduces some multi-threaded performance testing).

If you can test in a live 10Gbit environment and have 2 test boxes (PC's) which can generate and receive the traffic running through the devices, that will be a great test! :D

Testing the 2.5Gbit limit for switch ports is interesting though. Maybe you could also setup a test with multiple clients and then testing 2 switch groups and also in between them.

Today Im receive my RB4011iGS+5HacQ2HnD to replace current hAP ac(RB962UiGS-5HacT2HnT). After configuring it to same settings as hAP ac and connecting fibre module to sfp+ I get no link and spf+ interface start flapping:
mikrotik_sfp.jpg
Same configuration work normaly with same fibre module in sfp+ port on CRS326-24G-2S+RM(RouterOS mode)...

After researching and testing and setting different options it start working, then Im figure out that Im disable and enable sfp+ interface and after that it start working normaly... Im retest if this is true(only after reboot sfp+ have problems) and make workaround fix... Because I have on sfp+ pppoe client(and some vlans) Im made script which check if pppoe is connected and if not it disable and enable sfp+ port. Im also make scheduler after reboot and then every 15 seconds which run this script. Im try few reboots and shutdowns and it work without problems. I know that this solution will not work for users which don't have pppoe but maybe help someone also help fix flapping issue using different checking(some remote ip...)

So... got RB4011 (wifi edition) couple of days ago... It replaced my hapAC as well :) I just love it has encryption offloading (cpu usage stays under 10% pretty much no matter what - even wen using aes256-sha512). I am however missing USB port, LCD would be nice although not mandatory... And... Is it just me or is SPF+ port mounted upside down? I had couple of issues conntecting it to a switch using LR fiber optics cable, but disabling autonegotiation and setting 10G-full on both sides did the trick.

In my configuration disabling autonegotiation is not availible option because Im replace ISP Iskratel Innbox V60-U modem with mikrotik and put fibre and SFP module direct on mikrotik, that I don't need 2 devices, can send IPTV&VOIP&INTERNET on same UTP cable(Instead runing each cable for each device) and in this case I don't have access to ISP side to disable autonegotiation.
But Im happy that Im find solution to fix flaping link after reboot(Disabling sfp+ & pppoe client wait 5 seconds and enable both back - if do not help repeat procedure after 20 seconds)...

Yes, it is :D , seems the board is mounted upside-down too (the SFP+ cage and LAN ports are aligned to up side), the LAN ports are upside-down too, "release handle" (don't know how to name it in english :lol: ) on rj45 plug is up too, not down - this also indicating that the PCB is upside-down :) .
Also AKSN74 describing the case materials :)
3. The case is close to full-metal design (I know the bottom half case is plastic), the CPU is directly using thermal pad to touch metal case to cooling. The CPU temperature is not over 45C since started using.
So yes, main board is flipped over (or the CPU is only on top side, connectors, leds, etc. are on bottom side) so the CPU can touch a metal top cover which work as heat sink for CPU.

Would be nice to see HQ photos of what is inside RB4011 :D (both pcb sides :D and with removed thermal pads ).

I'm getting convinced more and more to RB4011 - I wanted to buy rb3011 as my home router, but I'm still hesitating because of the switch chip in rb4011 which is a bit worse than in RB3011, and the SFP+ port which I know won't work with 1G media converters build on Qualcomm chip (like MT RBFTC (yes!) or those cheap RJ45 10/100/1000M to 1G SFP) - Realtek chip based MC works fine (but those are very hard to get in reasonable prices)...
But looking at tests seems the CPU is pretty good match with this castrated-switch-chip, so I have to think really good about the SFP+ port issue and decide which to pick :)

It appears that having autonegotiation on one end and not the other is not a problem on SFP.
Of course on copper ethernet this is a definite no-no as it will end up in one side halfduplex and the other fullduplex.
But on SFP it appears to work different.
Did you actually try setting autonegotiation off and the correct speed and fullduplex, and what happens then?

Well... I didn't have such experience. For me disabling autoneg on S+RJ10 and connecting it to onboard NIC of device that doesn't support disabling autoneg simply resulted in "no-link" reported by that device and no connectivity at all. Lack of connectivity whatsoever is quite serious issue in network :P

You should not do it with copper ethernet, as I already wrote.
But with fiber it appears to work OK.
Maybe because it cannot work in halfduplex anyway and the speed can be selected to match.

Yeah it really sucks because S+RJ10 doesn't autoneg to gigabit. Even if there's 1G on the other end it still autonegs to 10G. It's terrible module like I said bilion times. Objectively. The only thing that saves its name is price.

Im not shure. When Im uncheck "Auto Negotation" I think Im together with checking "1000M full" also check "1000M half"(My mistake) and didn't work. It is on remote location and can't test this weekend... I will try again next week...

Hello,

I confirm the SFP flaping problem on the RB4011.
I'm using it with this 1G optical interface of my FTTH ISP (1gbps up/down access): https://www.flexoptix.net/en/sfp-bidi-t ... 3095=42306

I tried to disable autonegociation trying the different options, enable/disable, reboot, perform firmware update but it still doesn't work.
My access and optic has no problem and work perfectly on my RB2011 with SFP os this is really a problem with this router.
The optic is recognised in the RB4011 (see dump below) and doesn't indicate problems.

My question is : is it a hardware problem that cannot be fixed by firmware update ?
If this is the case then I will give up this router and look for another solution (maybe use a RB3011).

Thank you for your help,

You'll have to disable autonegotiation on both ends of the link for SFP to work correctly.

If you cannot control the setting on the remote end, the scenario is not supported.

fine no matter if it is configured for autonegotiation or fixed 1G/Fulldup at either end...
(before it was configured for autoneg but I have disabled it because we plan to change to a bidir SFP which works only
without autoneg and wanted to prepare the config for that. so first disabled it at one end, expecting a link failure, but no.

I can confirm 1G in SFP+ on 3xx series switches requires disabling autoneg. My 1G copper doesn't even detect link until autoneg is disabled.

Really happy with the performance on this device, replaced an aging RB951G that had to used fasttrack and the 4011 handles our 500mbps internet with traffic shaping and IPv6 tunnels with only 25% CPU usage. Only thing I want now is root to install DNSCrypt proxy - anyone found a nice way to root this yet? The RouterOS version it ships with has CVE-2018-14847 patched so I can't use the winbox exploit to create devel login, and no USB port :(. Hoping to avoid pulling it out of production too long, but netbooting might be the only way it seems.

Fun fact... According to https://wiki.mikrotik.com/wiki/MikroTik ... lity_table S+DA0001/S+DA0003 aren't supported but... Just tested S+DA0001 (SFP+DAC1M) with a Zyxel XGS 2210 the other side and using autoneg off, 10g fdx, and it seems to work (link up, data flow ok)

iirc MikroTik said that some kind of error correction that is technically required for passive DACs is not supported on 4011 but I guess if you don't have much of em noise in your environment and cable is short (like MikroTik ones) then probably it's not big deal thus "usually" it will work. In average environment.

Hello!
I have the following router
model: RB4011iGS+
factory-firmware: 6.43
current-firmware: 6.43.4
pgrade-firmware: 6.43.4

I have instaled SFP module S-53LC20D in SFP+ port of the router. The port has the following settings:
auto-negotiation disabled
port speed 1G
FD
A SFP module S-35LC20D has installed in a switch on the provider's side with auto-negotiation disabled
I think the distance is about 2-5 km

But i have seen as SFP+ interface flapping more times
dec/12 20:54:36 interface,info sfp-sfpplus1 link up (speed 1G, half duplex) 
dec/12 20:54:37 interface,info sfp-sfpplus1 link down

But i see as SFP+ interface flapping a lot of times.
That transceiver work as normal in a switch CSS106-5G-1S from my side. So the link has not issues.
I looked URLs https://wiki.mikrotik.com/wiki/MikroTik ... ansceivers and https://wiki.mikrotik.com/wiki/MikroTik ... lity_table
and i was sure that SFP+ port can work with SFP 1G trancivers.

Where is issue?

What's the cable length between those SingleMode transceivers? Rough estimate works. 500m? 1km? 2km? 5km? 10km? 15? 20km?

Weird... maybe try a 2 dB damper anyways? Then again, pretty sure you already tried that.

Then again, I try to avoid SFP Modules in SFP+ slots. Always likely to cause issues, even when "supported".
Could you try a pair of S+2332LC10D?

Just got the wireless version of the RB4011 with 10Gtek Copper SFP 1G for UBNT.

I initially encountered flapping when the SFP+ port was configured as LAN with autonegotiation enabled and connected to the laptop. The issue was resolved by disabling the port's autonegotiation and setting the speed to 1G, even though autonegotiation was still enabled on the laptop.

With that change on the RB4011, I've not seen flapping when the port is configured as WAN and connected to Arris SBG6580 or Linksys E4200 even though autonegotiation is enabled on the Arris/Linksys.

https://wiki.mikrotik.com/wiki/MikroTik ... ansceivers

[..] settings are needed to be set on both linked devices for required interfaces
Disable auto negotiation on both ends of link and the flapping will stop (tested and confirmed S-53LC20D @ RB4011)
Same goes for me - I could only get the link to work with an SFP module after asking the provider to turn off autonegotiation on their end as well.

Can this issue be avoided in a future RouterOS update or is it due to a hardware limitation?

There's no hashing algorithm that would allow all bonded interfaces to be used by a single connection (e.g. single TCP or UDP stream running, say, iperf). However, different hashing algorithms mean different probability that two connections will use distinct bond members. The only standard hash algorithm that makes probable use of distinct bond members for connections between same server and client (i.e. multi-stream iperf test) is layer-3-and-4.

so which will be the appropriate choice in case of smb (i'll say smbv3 with multichannel enabled by default)?
on the other hand, not every client [i.e. NAS] will accept layer-3-and-4

The highest layer acceptable for both sides. You might want to experiment with settings not being the same on both sides. After all, receiver will probably accept whatever arrives at any bond interfaces, most of the time all of them use same MAC address. The hash algorithm is important when transmiting to spread utilization of all interfaces as evenly as possible.

The high-level protocol doesn't matter. If smbv3 uses different tcp ports on either side (server or client), then layer4 hashing algorithm will distribute separate streams for single client evenly across interfaces while l3 or l2 will not..

So far the RB4011iGS+RM has been a great replacement for routing from my CRS125-24G-1S-2HnD-IN, I still us the CRS125 as a switch, but wireless is disabled since I use a wAP AC in the middle of my house. I did notice that the RB4011 gets warm even when its not doing anything, I had mine plugged in but not configured and was warm. So far my speedtests are consistently my max speeds. CPU has no problem with my big block lists every 12 hours only tipping the CPU up 5%. I did get a 10Gtek SFP fiber module (https://amzn.to/2BxD0RE) for both devices as an interlink, on the CRS125 it just worked with no additional configuration, on the RB4011 I was getting the disconnection problems others have mentioned, but I just set the SFP+ port to 1G Full Duplex and have no problems after setting that.
2018-12-18 13_55_40-Clipboard.png
The LCD screen was cool on other devices but I never look at it, and USB I don't have a use for, it would be nice if it was able to connect a printer or hard drive as a network shared devices, but I never worried for at home to have backup cell access. I would recommend this as an update for home or small offices for sure. If I didn't have a CCR1009-7G-1C-1S+ at work from the guys who run the WISP who couldn't use it, than I would get one for our small office.
Also the easiest way I found to get one of these was from a dealer through Amazon (https://amzn.to/2UWuXae)

I just switch from RB2011 to RB4011 and I do experience some weird things. First is known -> sfp module which I can bring to live by disabling auto negotiation and by repeated switching between 10G and 1G mode. Then at one point it starts to work and it works until the next reboot. Sometimes it connects at 10 sometimes at 1. At least it says so in the logs. Can't prove whether this is true.

Wireless works okeish, but the biggest problem (beside damn sfp) is that it happens all the time that internet connection stalls for a while (wire or wireless), there is nothing in the logs and when I do check speed tests its maxed out. My configuration, which is not that complex, worked flawlessly for years on RB2011 except the box become a bit slow on wireless and could not digest upgraded WAN speeds any more.

The question is: is this occasionally stall happening to you as well? On first glimpse it looked like DNS is not resolving, but I guess the problem is more sinister?

The problem persist with disabled auto negotiation, even between two RB4011 devices.
Issue reproduced between 2x RB4011, will be fixed in upcoming beta versions.

I unfortunately can't turn off autoneg on my provider's side, so I hope a software-side fix is possible.
I do not want to promise it, but we will look forward to add 1Gbps transceiver support with
auto-negotiation=on
on both sides. Generally in RouterOS it is necessary to force 1Gbps mode on SFP+(10G) interfaces.

Hi, if you manage to make it works this would be terrific Image, not only for 4011 but others RB/CRS/CCRs with 10G SFP+ too.

This might be solution for MediaConverters based on Qualcomm chip who don't want to work with SFP(1G) module when it's plugged in SFP+ cage :( .

It's actually really interesting because this particular 1G module:

https://www.fs.com/de-en/products/29838.html

Works for me with autoneg on in CRS317. So what is deciding factor that makes 1G module work or not? (it's worth to mention that their copper modules don't, so it really is just this particular one that actually works).

And to prove my point here's photo:
P_20190117_130556.jpg
I also tested this: https://www.fs.com/de-en/products/16271.html and it works as well. Connecting CRS to non-Mikrotik gear was also successful. Unfortunately I tried their LX modules and it doesn't seem to work (without autoneg off). That said I don't have 2 LX modules made by them so I tried to connect regular 10km LX to SX 1310nm combo MM/SM 2km. Maybe only one of them doesn't work with autoneg on.

So if you need LX modules and want to bite a bullet (not that 14$ sounds like kidney tbh) then I guess you can try it. If you need SX then go on. Here's how it works on CRS. I don't have RB4011 to test tho. This topic intrigued me so much that I'll probably buy another LX and another SX/LX 1310nm combo just to see whether it works. But I need to wait for salary so not this month as I'm broke ._.

I knew it's unusual from very beginning that they worked with autoneg on, so I even asked FS.COM support what's their sorcery but they didn't reveal it xD. Maybe @mikrotik you could ask them how it works to implement such thing in your official SX/LX modules? Or just simply OEM from them lul.

By the spec sheet:
DC jack input Voltage 12-57 V
Max power consumption 33 W

Now wondering, when powered on 12V how much Amps should PSU provide?
Spec sheet does not say anything on which voltage that 33W is consumed.

Does anyone has any idea?

Re: RB4011

Posted: Thu Jan 17, 2019 11:50 pm

P = U * I (Watts = Voltage * Current)

So when you have 12V at 33W the current is 33/12 = 2.75A.
When you are running it at 24V, current is 33/24 = 1.375A.
(those are probably "maximum" values, not what it will draw all the time)

Why is the current becoming less when the voltage increases? Isn't the current increasing due to Ohms law? (U = I * R)
No, because equipment like this contains a switch-mode regulator, that actually converts power from the input voltage
into the desired output voltage that internally operates the electronics (e.g. 5V or 3.3V). So when the voltage drops,
the current increases to maintain the same power.

Try and update to latest stable first, if the problem then still occurs, open a support ticket and run a support out file so they can diagnose the problem. :)

I know the Ohm's law, just forgot about the Watt to Amp relationship...and switching power supplies related stuff... :D

Actually, my general plan is to use single power source for three devices, all of these can handle 12V input, so...it is simply question about the Amperage.
Seems like 12V 5A powerbrick, wired into UPS is plenty.

hi..ive got RB4011iGS+5Ha... for 3 weeks and about 2 days ago i figured out that 5GHz wifi "start disapearing" after about 1 day in wifi interfaces i can see its in "running ap" status but i cant scan it on another devices (2phones/1ntb) when i try to disable and enable it again it will never get to "running ap" status agan it stucks in "initializing" phase.. i have to reboot whole RB to get it working again..
problem occurs on ROS 6.43.8(firmware version matching ROS) and 6.44beta61(firmware version matching ROS)

previously ive got CRS125-24G-1S-2HnD i was able to achive uptimes >200days (rebooting mostly due to SW/FW upgrades..)

quite annoying.. anyone else having these problems? any way to solve it? or RMA? thanks for sugestions..

Hello,

I'm having exactly the same issue on my 4011.
2.4GHz WIFI works, but 5GHz wifi disappears every 1-3 days. Interface is up but other clients cannot detect the AP. I need to completely reboot the device to get it back online.
I've opened support case with Mikrotik but so far no luck.

We are trying to reproduce your mentioned 5ghz wireless issue, currently everything works for us as expected. We will appreciate information which could help us to reproduce the issue, maybe someone can provide us step by step guide how to trigger this glitch?

Hello, I just want to report I am having this same issue as well. The 5ghz is dropping frequently. I enabled the logging to echo but didn't see anything of value, the interface just stays in "initializing".

I have been playing with the settings over the week, I was not getting the expected throughput (100Mbps up and down, eventually got it too ~190 down; ~400 up). The ISP provided router was closer to 300 down, 400 up (using the speed test app on my phone); the WAN connection is 1Gbps. I set the Channel Width to 20/40/80mMHz XXXX, frequency to auto, Country to Canada, installation to indoor; Distance to Indoor; disabled WPS; WDS is disable; I tried fixed tx power rates at 17 at well.

Hi everyone! I'm new to the forum and to Mikrotik. Just got my RB4011 a few days ago and got the basic configuration complete, and was happy to replace my old tp-link router once and for all. I am certainly no network engineer, but I was finding myself frustrated with consumer network products. A friend of mine runs a wifi internet provider and swears by Mikrotik and recommended them. I also looked at Ubiquiti, but the RB4011 ticked the most boxes for me. RouterOS will take some time to learn, but on the whole it seems really well built and expandable, and I'm really happy with the product so far.

The only thing I was underwhelmed with was the wifi. I was hoping to be impressed, but actually it's been a downgrade from my midrange pre-MIMO tp-link ac router. It has generally seemed a bit slower to connect, range is about the same if not a bit less. Speed is ok, but sometimes it seems like it hangs for a while. I'm on fibre internet, so it's unusual. Also it seems to either drop occasionally or restart a bit more than I'd expect when I touch anything in config. I can't always tell if a page is just loading slow or if it's a router issue, it just generally feels a bit less stable and less solid than I'm used to.

The only thing I can find in the log when the wifi drops and restarts is the error msg below. The strange thing is the admin user is disabled and I'm logged in using a new custom user with admin privileges. It always points to my lan ip, so it's not like I'm being hacked... At first I thought I have a setting wrong, or that a browser plugin was interfering. But I switched to winbox and notice it happened again. So, since I came across this thread, I thought I'd ask to see if that sounds similar to what you guys are seeing, so I don't start tweaking all kinds of settings for nothing.

Thanks for the help.

Hi, i have a problem with my mikrotik 4011

when ethernet cable plug-in in port eth2 or eth7 green leds are not blinking, but connection is working.
If plug-in cable in other ports then i can see the green led
in connection i use the same cable.
anyone know what is it ??

when routers loaded all 10 leds are blinking

To those having bad 5Ghz problems, do not choose auto. It may be that MikroTik is choosing a dFS channel and not all modern devices support DFS channels properly.

Thanks for the tip. I found the same out on my own, and things were working better for a while, but today the 5g started acting up again. The router says it's enabled, but it doesn't show up in my list of wifi networks on android. Have you found any other tweaks that work?

I don't believe I did anything to trigger this, other than disconnect leaving nothing connected to the AP. The next time I went to use it, hours later, the AP was gone.
I also was using a virtual AP when I first got this.

Ouch. Any particular reason to go with such setup? Existing, long cabling? 10G-SR modules cost like 16$ plus few bucks for LC optical patchcords comparing to 65$ for S+RJ10. 10G copper seems to be insanely expensiive. Especially non-mikrotik modules which go for like 150$.

I can not use fiber because of my existing cables. The only one problem with RB4011 is the high working temperature of the SFP+ module.

So I assume you use longer copper cables if replacement would be problematic? What cable length do you use? I was always interested in actual maximum cable length for 10G copper modules. Because declared 30m sounds like rather "better safe than sorry" requirement. Not real limit where transfare rates start to significantly struggle.

oh. Well...

10G SR module 15$ x2 : https://www.fs.com/de-en/products/74668.html
10m OM2 LC-LC patchcord 5$ : https://www.fs.com/de-en/products/74394.html
total 35$ (or 42$ incl. VAT)

S+RJ10 65$ x2
cat5 cable 0$
total 130$

actually even using original MikroTik SR modules (60$) it still saves around 5$ xD
Mostly because S+RJ10 is really cheap comparing to other 10G copper modules. With "normal" copper modules for like 150$ optics are ridiculously cheaper, more than 10x cheaper.

That's why I was a bit surprised a bit.

I agree with you! But my tubes in the wall are full and it was a quick and dirty solution :-) If i will have to interconnect my equipments in the rack than the optic modules will be the solution.

The 802.11ax standart is knocking on the door.
So Im wondering if its possible to replace the existing rb4011igs+5hacq2hnd-in mpcie card with a newer 802.11ax generation when its available ?

Will it be possible such a feature to be implemented in a near future ?

Most likely not. Waiting for a new device. I hope it will work immediately without any problems.

Thank you !

I bought this router 2 months ago because I prefer that kind of hardware - all in one. I don't want to use router, switch and AP as separate devices.
Most of users like me use this unit for domestic needs .so we prefer to be all in one device.
I waited so long to buy this router because now ROS is much better than before especially in terms of 802.11ac performance. and SFP usage
So I dont want to spend another 2-3 years waiting new device to come (RB 5011 may be .. )

I don't see why mPCIe card wouldn't be replaceable, as long as the new one will be supported by RouterOS. You can't just buy first card you see, because RouterOS definitely doesn't support all chipsets, but once some mPCIe ax card from MikroTik comes out, it must work.

Yep I mean card from Mikrotik for sure.

That would be very useful despite of this that would run only at 2.4Ghz spectrum because of the antenna .

Also interested in the flexibility of that m-PCIe slot. If I got the wireless version, could I pull the existing card and put in the R11e-LTE to have an internal LTE modem? Antennas would need to be added but that is fine.

If there is a Sim card slot on board then you should be able to insert gsm modem card.

Note: The RB4011 does not support Passive DAC modules, 1GB copper SFP modules and SFP GPON modules.
Would support for GPON ever change (firmware) or is this a hardware issue? If we want GPON should we stick to RB3011?

Natively rb4011 don't support 1G in sfp+ but there are modules that do work when the sfp+ is hard-configured to 1G (1.25). Check topic Usage GPON module SFP in Spain there is one or 2 person's who confirmed that some GPON stick do work (those directly from Chinese manufacturers in which you can change sn/password/etc...).

Can anyone tell me what I might expect routing between 10 subnets using just the sfp+ connected to CCS326 might give me? Currently, I have a FortiGate 200b as my Firewall/router and it will remain the firewall to the internet, but when I am running test on some of my esx hosts that are 10G capable its maxing my CPU on my FortiGate. The fortage currently has 22 inter VLAN rules to allow traffic to pass there rules are mostly whole subnet to whole subnet on one port. Some rules are a few ips to a few ips, seems pretty simple.

I don't expect 10gbps and I don't need it, would be nice for the testing but I am realistic person its a 190.00 router. I just want to be able to run my test and not take down my network. If you say I need to save my pennies maybe I just need the 1009.

Depending on load characteristics RB4011 will outperform CCR1009. It will easily pull off 10G, just like CCR1009 (providing you use fasttrack in firewall, otherwise not rly but CCR1009 won't either). RB4011 will be better at handling fewer high throughput connections while CCR1009 will be better at handling thousands of smaller connections saturating 10G interconnect. It makes RB4011 great router if you're streaming or routing storage, hosting big files etc. - scenarios where CCR1009 sometimes struggles to hit 10G. Those devices are similar in overal performance - they're just optimized for different load characteristics.

TL;DR RB4011 is really capable router and my friend uses it for 10G inter VLAN routing with CRS317. It pulls off 10G without a sweat in most scenarios (except large scale with thousands of tiny connections).

Imho as of now RB4011 is no brainer unless you need some specific CCR features like smart card, additional SFP interface, usb, microSD, higher throughput for gigabit interfaces (because RB4011 has 5G aggegated bandwidth to gigabit interfaces - 2.5G per switch, while CCR1009 8G aggregated for 8 interfaces - no switch chip). And I'm saying that as CCR1009 owner. I just keep lying to myself that I totally need this touchscreen LCD so I don't feel like I wasted money...

I agree the RB4011 has lots of grunt. I have just set up a site with 17 CAPACs and am using non-local forwarding CAPSMAN configurations running off some bridges in an RB4011. The RB4011 is connected to a CRS328 switch using only a 10Gbit SFP+. Given my experience using 12 CAPAC/WAPACs in a similar setup using a hEX (amazingly it copes very well with the load) I don't anticipate any problems.
