I have instaled SFP module S-53LC20D in SFP+ port of the router. The port has the following settings:
.............
Where is issue?
What's the cable length between those SingleMode transceivers? Rough estimate works. 500m? 1km? 2km? 5km? 10km? 15? 20km?
I'm pretty sure we're looking at a dampening issue here.
I think it is between 2-5 km
But i forgot notice that transceiver work as normal in a switch CSS106-5G-1S from my side. So the link has not issues.

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?

so - is the 160mhz channels option working?
just tested with a killer 1550 client, intel-based, capable of 160mhz, no success
doesn't matter which client i'm using, ap isn't available anymore, until is set back to 20/40/80.

offtopic a bit - could someone point me to a topic discussing LACP? i haven't succeeded to obtain more than 1gbps ... one of lacp members stays relaxed, doing nothing :)
also, wins server / master browser? thanks in advance!

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
by pe1chl
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 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.

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.

not using any virtual APs on 5GHz an still have issues.. but its very random right now 8days uptime without problem..

Has anyone notice one and the same mac address on sfp+ and wlan1 interfaces???

Just after upgrade and reset-config:

Anyone managed to try the new S+RJ10 with the 4011 yet? (the /r2 hardware revision)

Yes, i am using S+RJ10 modules between RB4011 and CRS328.

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.

It is less than 10 meters CAT5E without shild.

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.

Re: RB4011; 802.11ax

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.

Thanks Sob

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?

What is the reason for this limitation?

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...

Had an odd issue recently, my 4011 seemed to have a thread stuck at 100% CPU. Had to reboot to get it to go away. Anyone else seen this before?

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.
