If it's really the antenna gain setting, then manually lowering tx power would fix it as well. Antenna gain just limits maximum power to obey regulatory domain.
It's not exactly the same thing. RB devices have a "Tx power backoff" kicking in at higher modulation modes (higher MCS). If you limit Tx power in a wrong way, then it will get lowered at higher MCS as well. If you set antenna gain, RB will linearize Tx power ... so that there won't be any Tx power backoff any more (if antenna gain is large enough).

So I have a customer router that's a 4011 and I set the antenna gain to 3. One device has been connected pretty much all weekend and it's between -70 to -83. The 5g sometimes gives a group key exchange timeout to all connected devices but other times (and here's the interesting one) it'll give the Mac address of the device and state XX:XX:XX:XX:XX:XX@WiFi_5g: disconnected, disabling. It then proceeds to do that on all connected wireless devices and at this point the actual interface has dropped and you can no longer see the SSID anymore.

Damn it! : D, As I have not found before? !!!!
Colleagues, pay attention to the mac address sfp-sfplus1 and wlan1
they are the same! Change to sfp-sfpplus1 mac address.

It's all about the same mac address with sfp and wlan1!

How could this happen to the manufacturer - Mikrotik?! is another question!

You are absolutely correct. I saw this even on our device. I however manually override this to what it should be on ours and the disabling is still happening. Another thing I find odd about the RB4011 is that wlan1 is 5.8 and wlan2 is 2.4 while on the hAP AC and cAP AC this is done in the reverse.

I already wrote to the support that when registering with the controller RB4011 - it glows with auto-assigned mac addresses.

A mess in general.

And what the hell?! switch chip doesn't work? is it the same as in AH1100, is there anything to hide?
What would we not see host table?

This should have been fixed long time ago. Bug like this just kills entire product.
Meanwhile MK is still selling RB4011 WIFI version that's clearly flawed and part of it (5GHz WLAN) is completely unusable.

It's easy to just say "if you don't like it, just RMA it and you get your money back"... yeah... NO.
If you made a stupid mistake of giving RB4011 to your customers, you now have to spend your time to answer the support calls, to apologize on behalf of MK and to replace it with something else that works. This sucks and you just feel like an idiot for even buying this thing.

This entire issue is hurting MK far more then they think.
It's impossible to even get any status update (is the fix likely? can we expect it in weeks? months? or even this year?) out of MK.
How many people are working on this issue? Probably not enough.
Usually silence means bad news and this is dragging for far too long.

Anyone buying RB4011 for SOHO use, where you want working 5GHz WIFI, abandon any hope...

i presume there's a major difference between rb4011 batches; for example, mine, bought from romania, have no problems with 5ghz wireless, besides 160mhz option not functioning; also, there is a "antena gain" setting in winbox, with "3" set as value by default.
also, there is that problem with the same mac address for wlan1 and sfpplus [i added 1 for wlan 1 value, but the router worked before without this modification...using both wlan1 and sfpplus!]

At the frequency of 5 GHz RB4011 there are other access points?

Can you take please a picture of the mac address sfpplus and wlan1?

only a few - in the nearest neighbourhood [very thick reinforced walls between apartments], with pretty big attenuation.
mac address was modified, no "reset mac address" option there in winbox for wireless interfaces. so a picture taken now isn't relevant... you must trust my word :)

In the logs and debugs, you will not see anything, this is an error of the level of L2, the mac address is the same and changing them on the interface does not help, something else inside RoS, is still at the level of L2. Note that the switch chip is the same as on the AH1100, but the host table on RB4011 is empty!

We are discussing here, and the support does not solve the problem which is obvious.

Another moment during the registration of RB4011 in CAPsMAN, he identifies himself with the self-appointed, left mac address.

I think that this is not critical, because the interfaces with the same poppy are not connected to the same second-level network segment (Ethernet). Moreover, probably, almost no one uses the spf-spfplus interface. I have it turned off, but I am seeing an increase in packet counts, pause frame. This is most likely a bug.
The screenshot below is from my RB4011.

TimurA, I of course agree with you that with the same MAC addresses on two interfaces this is a mistake of the developers of this Mikrotik model. Moreover, on the box from the device for wlan1 one poppy is written, and on the device itself another. But it all depends on how the device itself handles this situation. As a result, this may or may not affect the fact that the radio interface stops working.

No, Intel wlan chipsets are unsupported in ROS. Only Atheros may work.

Re same MACs: While this is probably another bug in RB4011, it's not the culprit for 5GHz WLAN troubles, because they happen even when SFP is not used and disabled.

After today's 5ghz experiments, the following can be summarized:

1. switch chip does not work in bridge mode.
2. Mac adresss duplication on sfp and wlan1
3. curve driver for wlan1, does not work on 4 chains.
4. 160mhz not working. - This is superfluous, here 802.11ac does not work correctly.
.......

like some of minipcie adapters based on qca 9880-9882-etc.
how ROS will handle the dual-band adapter settings, in this case? academically speaking, as long as the marketed functionality isn't achievable.

I received my RB4011 last friday. Very happy with the design of the device. I use it as a replacement for my RB2011 which has been running perfectly for about 5 years.

I backupped the running config of the RB2011, and selectively imported this script to the RB4011. Everything seemed to be running fine, but after 24 hours, the 5GHz network disappeared. I rebooted the device, and it was available again. Last night, again after 24 hours, the network disappeared again.

The wlan1 device is enabled, but when I open it, it says 'not running'. Also, under status it shows the date the link went down last, but it seems it never came back up.
I have the RB4011 WiFi version and don't see this issue. Did you/are you able to capture a supout <10s after the radio goes down?

In my case the 5Ghz doesn't disappears (it is named like the 2Ghz band), but the device doesn't connect after a few hours running.

Entering in WinBox, the 5Ghz appears as "Not running" until rebooted.

I ran a RB4011 at home as a wireless access point only, for about a month.

While it suffered from the same... "Can't go faster than about 300M on speed tests..." (This has been the case with every Mikrotik Wireless I have tried.)

I can't think of a time when the 5G was not accepting clients.

I set the 5 GHZ Channel to 20/40/80Mhz Ceee and frequency 5180. This worked consistently and carried an average of 20 clients at a time. I had as many as 50 on the unit when we had guests over.

I have the same problem.
Some time the 5Ghz wifi stop working.
I tried disable and enable again but is stack in initializing and not running.
Tools like "scan" and "freq. usage" dose not return any result (with 2.4GHz work perfect).
The signal of 5GHz is disappeared from any devices and none of them can connect (only in 2.4GHz).
I believe with reboot, that work for some time and next i will have problem again.
But... in a router the reboot isn't so easy.

I had many strange problem lately with the unit, but the wifi was the perfect result and working fine all the time. 2.4g and 5g have 2 different ssid name. txpower manual. no country set.
20/40/80Mhz Ceee, detect fine 5g 433mbps. Putting 160mhz is for very new device, there's not much that work with the 160 freq and especially no phone and neither the iphone and other istuff.
Also, with the higher band.. wasn't it supposed to cut the signal and modulate the power when no packet are needed instead of having all time full power.. ? Using eth cable or the sfp will fix all the problem if it's a fix unit or so and you need full all the time.

For the other issues, i did another netinstall, and then it pop up fine. it show rb 6.43.3 firm and upgraded 6.44.3 , ipv4 fasttrack by default at on. 24v around 39degC

No wireless settings combination works for me either - no matter what the card freezes after some hours where the only way to fix it is to reboot.

The registration table shows 1 client connected (which isn't), however there are no SSID broadcasts occurring. The AP got into this state after a prolonged period of co-channel interference. It is highly likely this is a Qualcomm proprietary qca9984 driver bug caused by missing state update (eg an unlock) on an error path.

Yes, not fully working RB4011 devices at 5ghz and hap ac2 on qca9984 chips.

Why did they let them out ?, it's not at all clear! only trust undermined.

This issue is still being investigated by our development team. Unfortunately, this is taking longer than expected because it is not easily repeated. Any additional information regarding to "disappearance" of the 5Ghz wireless interface and how to replicate it would be appreciated and could fasten the process of resolving this matter.
Just connect xiaomi mi box mini to the rb 4011 or hap ac2, 5ghz will disappear soon :)

We halt purchasing RB4011 with wireless. My personal one now has hAP AC next to it for 5Ghz.

MT: really, seriously, this is a joke. The device is mostly punched as a replacement for RB2011/3011 which packs more ports than hAP AC. Having non-functional 5Ghz makes is literally useless.

RB4011 Jaś R11e, but it’s responsible for handling 2.4Ghz. The 5Ghz is handled by a built-in QCA9984.

p.s. just coming back from emergency replacement of post-thunderstorm of 2x RB4011 - switched to hAP ac + switch at one location ;p

Yesterday I bought a cAP ac and had the same problem as the 4011 on 5GHz. After set-up he began to emit normally at 5GHz and after ~ 5 'ceased to operate the particular band. At this time, both cAP ac and 4011 have the 5GHz band stuck in enable / disable running / slave / initializing. The scan / freq options. usage does not work.

Yes, you right! I also wanted to buy ubiquiti, but mikrotiks fanboys convinced me :(
These are my first two devices from mikrotik, rb4011 and hap ac2, and both do not work properly...
Mikrotik can not solve the problem for almost a half of the year and I do not think that they will solve it.
And I am lucky that I use these devices for home. I wanted to build a enterprie project on mikrotiks devices.
But no more mikrotik in my life...I'm also trying to sell them out and buy ubiquiti.

Have you try to first install fresh with netinstall 6.44.3, and then only used the: quick set and just put a password and a name ? No vpn, no port blocking.. no nothing. I'm on 20-40-80ceee , freq/chan : auto, no country set. ap-bridge and i get full speed and no disconnect at all. ssid always present.
And do you get disconnect when you are under 15feet ?
It could be extra setting you put/change.
If you want a constant link, perhaps go with eth cable, as the AC protocol is not made, intended to be transmitting 100% power all the time and keep the link open all time.

The ac is perfectly stable on other devices. We have plenty of hAP ac's and wAPs and there are no complains. Seems like only QCA9984-based devices are problematic.
The issue is not with disconnections but with the SSID being gone. From what I've seen in the lab as well as from the feedback of other people the issue is only present when nothing is connected to the 5Ghz AP for too long.

I found a way to make at least this piece of shit work.
We do the following: in the ACL for 5ghz, we write the rule limiting connection -120 ..-65 (or -67).
5GHz is falling due to the fact that the client starts to reconnect frequently.

Mikrotik! solve this problem already, how much can you analyze?

So why it fails when there's no clients at all? After a long period of idle?

My observations show that rts/cts disabling may help. Still investigating.

Yep, running for 5 days or so. But maybe "adaptive noise immunity" disabling helped also.

No. I'll enable it and check if my wlan is unstable. So far so good.

These units are not cheap at all (230+ EUR) to purchase, and they can't even perform their basic as-advertised functionality in a reliable fashion, for Pete's sake!

Hello, Frostbyte, I have the exact same situation, 7 months. No response and no response that the device is defective. The only thing that I received from the support is that they have been working on the problem for 7 months already. This is sad!

They write that they fixed 802.11ac for ARM, but in the end it was frustrating.

In my regions, all distributors - seeing my problem do not order the RB4011, for fear of return and complaints. And this is all that I could achieve.

i still believe that it's a hardware version problem; i haven't this problem with wlan1 disabling itself (router bought from romania, in december 2018).
for sure, 160mhz option isn't working, even if the settings say so; and only once wlan1 started to search another free 5ghz channel, due of meteo radars relatively nearby [an anti-hail rockets system at ~10km], kicking me out for those regulated 10 minutes.

PCI info of RB4011 - Atheros Communications Inc. unknown device (rev: 0)

Most likely the problem is in the wifi chip, it is previously a revision. According to the openwrt people Atheros QCA9984 rev 1.0, and the problem was solved by the firmware of the chip back in 2018. I am very disappointed in RB4011. I do not want to be more impressed. :evil:

@mikrotik seems to me not looking there at all. Constantly write increased stability in 802.11ac. wlan1 often crashes when a device reconnects to RB4011 from another device.
And there will be ipv6 - multicast.

and here are the links to fixes on openwrt on the QCA9984 chip:

i hade wlan1 was always in the bridge. If wlan1 is removed from the bridge, then it stops falling, and the red diode goes out.
In the case of CAPSMAN, I installed a datapach for wlan1 without Local Forwarding, and it also stopped falling, and the red diode is off.

@mikrotik, why should an expensive router users themselves look for your problem? We have been talking about the problem for 7 months already, and you are silent - like a fish on the ice! You have a problem with ROS in the bridge for QCA9984!

something makes wlan1 fall, obviously not the correct processing of data from wlan1. If refer to patches from openwrt then multicast.

160mg is for future, if people try or complain about an iphone not connecting at that speed.. the istuff don't support it. The ac norm is not made to be all time on, it's an hashing power. Better to used the 10g fiber port or simple eth cable to have a full conectivity. Why wifi is so needed ? Only a battery operated stuff need it, the rest, as soon you need to be plug to the ac, you can have an eth cable.
Do a netinstall, do the simple ac setup /corner left and all is up and wifi work without disconnect. So no vlan, no ipv6, no extra firewall stuff... This is the basic first step to do before saying it's not working. and not after a-b-c-z mod and addition of vlan and multiple subnet and so on..

Cutting off multicast completely is probably a terrible idea since many applications rely on that (AirPlay, Dropbox just to name two).

Also, phones are pretty capable of ac but they rarely use it due to the battery consumption.
8946D612-1D8F-4202-979E-AC82028F24F8.png
Tablets and laptops in the other hand... well, ac is needed.
I want to see how you drag Ethernet cable to a TV, thermostat, smart speaker and all different things which are wired to the power but connected to the WiFi for convenience. You cannot tell your customers that you will rip their walls and connect everything using an Ethernet cable... cmon, it’s 2019.

p.s. also the point about ipv6 is completely missed. A lot of systems use IPv6 in the local network. Disabling IPv6 nowadays is like refusing to use LTE.

how much can we do netinstall! Do you think idiots here?
if we do not use multicast, vlan, ipv6 and so on - then why is this neutered device needed?
Can take ASUS or Tp-Link for morons and everything works without tuning.
Synology RT2600ac - QCA9984, there were similar problems, even in 2018, and they solved them.
In the framework of this forum, I gave a link to the forum of theirs.
PS
Do you think I did not with an empty config and did not check?!. @Mikrotik has a ticket with suppot files and not one. And not only from me open tickets.

PS
Synology - they screwed WPA3 back in 2018, CARLL!
Synology RT2600ac Release Notes - v1.2-7742 (2018-10-16)
Added support for WPA3 Personal/Enterprise

PS
on the other hand, they release 6.45.2 and send an SPF port to hells. A week has passed and no warning in the description of a stable branch, and if it were not for the forum, many would suffer.

Sorry but i cant verify.
I removed wlan1 (5ghz) from bridge but still dose not work.
I tried disable/enable but... same problem.
I tried add to bridge again but... nothing.
I tried all combinations with above (without restart) but nothing worked.

5ghz work only after reboot and for limited time.

I can't suggest too much aside of 6.44.5 but I currently have it set up in 80+80 mode with statically configured frequencies. Specifically
set wlan1 band=5ghz-n/ac channel-width=20/40/80mhz-XXXX frequency=5200 secondary-channel=5530
I do have
adaptive-noise-immunity=none
(and I remember ANI being a massive pain on OpenWRT in the past) but it was off the whole time before anyway.

I actually had a massive amount of trouble setting up 80+80.
For first bunch of attempts "set secondary-channel=" command was accepted, returned me to prompt... but crashed the wireless subsystem.
Both 2.4 and 5.0 wifi go down, and many commands such like /interface print (not to mention /interface wireless print) just frozen the console.
A minute or two later I've been also losing the ability to open new ssh connections - key was accepted but then terminal hanged in blank.

Only fix for that was a power cycle.
Actually, no, that was a long night and I forgot the whole story.
Because the faulty config was already saved, after a reset I could log in but wifi was still crashed and trying to do e.g. /interface print would freeze the management plane again.
So after that power cycle it was actually required to restore backup, which would then say it will restart but fail to do so (because crashed system components).
Manual power cycle at that point brought me back to the config from backup, so with the ability to edit wireless config again.
So, try another setting, freeze the device again, rinse, repeat.

I'm still not 100% sure but I think what resolved this was setting
channel-width=20/40/80mhz-XXXX
.
Earlier it was specifically
channel-width=20/40/80mhz-Ceee
on the assumption of "if I'm setting frequencies manually, I should set up the control channel position manually too, right?".

But... yeah. Works for me for now, at least.

PS. Can anyone point out to me what's the logic for the code-tag to sometimes render inline and sometimes as a box?

It was discovered empirically that macbook pro 15 "2017 and macbook pro 15" 2019 are to blame for the fall of wlan1. There is no such effect on windows 10.

this is in my case.

ps
maybe it's itunes wifi synchronization with iphone, ipad behaves like this or Airdrop or something specific - which I don’t know.

ps2

disabled AirDrop everywhere until the interface crashes. I will watch.

Please write to support@mikrotik.com, providing supout.rif from your device generated after the crash (when the interface is "down"). Additionally, If you know how to repeat the issue with your setup, please provide detailed steps.

Is the RB4011 5GHz issue resolved?

Hello Normis,

No, the problem is not resolved.
we sit and watch you :) when something is decided :)

PS
I sent new data to Reiniss, and my conclusions about the SSID drop.

Timur, I understand from Reinis, that your problem is not related to wireless at all, it's most likely a Layer 2 misconfiguration problem. My question was to the other participants of this thread.

Normis!

here it is not a level 2 configuration. You have some problems with RoS on L2. Since it affects wlan1 but not wlan2 - how can you explain this? When all the interfaces are in one bridge! And checked without a bridge! Let's not throw off the problem for a special case!

You DanielJB and others described the same symptoms. ping increases and SSID translation stops

/caps-man remote-cap print
# ADDRESS NAME STATE RADIOS
2 172.27.0.1/58405 [11:E9:4B:BF:AB:CE] Run 2

Explain to me what is going on on L2 in RB4011. When the device in capsman constantly generates a left mac address. Non-native!
I already mentioned this to Arthus and Rudolfs and Reinis.

PS
Remember how we resolved the issue of identical mac addresses on SFP and wlan1 for a long time.

Timur, nothing is wrong with your 2GHz, because nothing is connecting there. Please be reasonable and follow our support department recommendations, your configuration needs restructuring.

Normis, look carefully suppout the files, after the fall of wlan1 everyone runs away to wlan2.

Hello Denisun,

Another working method I have. for wlan1 set the parameter Frame LifeTime> 0. etc 2.00 or 3.00.
You can already enable Local Forwarding in CAPSMAN.

The problem still exists.
For me it took about 29 days on a brand new RB4011, before it occurred.
Since then the wifi gets disabled (stuck in "initializing") in less than a day for 3 days in a row now...

I have it in auto.
I believe it tried to find a free channel and it was delayed.

In this case the delay is most certainly caused by DFS (radar detection). When a DFS-enforced channel is selected, a delay (before you see your SSID on air) of at least 10 minutes is always to be expected.

Hello team. Sorry, but I think will be better if we all bury this “perfect and best solution “. I’m reschedule all my critical projects on “old” hAP AC and now I’m happy. 35 days without any problem.

I second Nitrox's statement. You cannot leave anything on Mikrotiks in capsman or the wireless interface auto for anything related to channel width. I personally have repeatedly experienced out in the field and while testing in our data center this wrong extension channel selection. One channel I have seen this on for sure is ch165 being used in extensions, which from everything I know is only a 20mhz channel that is not part of Ceee eeeC or anything other than a lone 20mhz channel. Also why can you not exclude DFS channels outside of capsman? With custom channel list you can of course but why not otherwise like capsman has?

Re: RB4011: wlan1 disabling itself

Posted: Fri Sep 27, 2019 2:51 am
by UpRunTech
I'd say perhaps there are clients out there that don't work well using anything other than Ce or Ceee. Options like eCee or eC or eeeeCeee are there so the radio can find a clear 20MHz space for C and optionally use the e's depending on the radio interference environment. For 5GHz indoors this shouldn't be a huge problem, even in apartment blocks as 5GHz doesn't propagate through walls very well. Maybe outdoors this could be a bigger problem for 5GHz if there are a lot of PtP and PtMP links. For 2GHz just stick with a 20MHz channel on 1, 6 or 11 with b and g disabled. That said clients may not negotiate anything other than Ceee/Ce very well anyway - at least with Mikrotik. I have found the less choice or variety you give both the access point and the clients the better the outcomes. And always set multicast helper to full - discovery broadcasts and DHCP works much better with it on.

Here's my example of a recipe for happy CAPSMan and is typical of what I use. It works well with HAPAC2 and CAPAC. I have an RB4011 with Wifi but I found a bug the other day where it will always do Ceeeeeee when I only ask for Ceee - and Mikrotik have acknowledged this bug and will fix it. CAPSMan doesn't even give your a choice for Ceeeeeeee - at least in Winbox.

Put this mangle rule on all the APs if you use local forwarding, otherwise it only has to be on the CAPSMan controller.

Issue is still at large, support hasn't responded to my emails since July 22.
Unfortunately on the secondary device, downstairs, one of the client devices is a xiaomi mi box..
I also noticed that on the primary device, upstairs, a nintendo switch will also make the 5GHz band fail after a while..

At this point I think we need to create a fundraiser to buy and ship some of these "problematic" client devices to MT so that they can finally troubleshoot/reproduce in a reliable fashion. :lol:
Honestly, this joke has dragged on too long.. Especially to those of us who bought the device on release and we're closing in to a whole year without a basic functionality working proper.. I shake my head..

But I'm not going to give up, nor on the 5GHz stability, neither on channel 50.. We flipping paid every pretty penny for all those features..

And what do you offer? Just send them devices? Or something specific?

I know that there is an error on L2 during data processing from wlan1 to the CPU.

I'll try today to agree to take a test from a new batch of the device. If there are no problems there, we need with you and the community to decide what to do with Mikrotik. How to act.

@TimurA

If it's a hardware revision issue, then the obvious would be to demand an RMA/replacement.

The only thing that I disagree with is us sending our devices over first. For good or for bad, the two RB4011 units are the core of my network.. and I will not be accepting ending up without a network on my home (on top of suffering from that WiFi issue for almost a year), because MikroTik is unable to send a device replacement in advance (upon receiving proof of purchase of course).

TL;DR: They send the replacement first, then I send them the faulty one back. Not the other way around. And I will not be accepting to be charged even one penny for their f-up.

You can calm down, there is no difference in the revision of RB4011. Everything is just as bad on the new device.

the one that was tested is released in March 2019, my old one was released at the Sep of 2018.

All symptoms are the same.

I honestly doubt this is a new hardware/mainboard revision. It's more likely that the new unit you got, only got assembled at a different date and factory.

I sincerely hope that the issue lies within the software and not on the hardware. Time will tell.. Just how much more time it will take, that I do not know..

colleagues, disconnect Discovery on RB4011 and on neighboring Discovery devices. And check out the work of 5ghz. There is a suspicion that because of this the storm is on L2, and 5ghz has problems. The feeling is that all the problems are due to Realtek RTL8367.

Colleagues, I completely blocked the CDP / LLDP in the bridge with filters. 5ghz does not fall.

add action = drop chain = forward dst-mac-address = 01: 00: 0C: CC: CC: CC / FF: FF: FF: FF: FF: FF
add action = drop chain = forward dst-mac-address = 01: 80: C2: 00: 00: 0E / FF: FF: FF: FF: FF: FF
add action = drop chain = input dst-mac-address = 01: 00: 0C: CC: CC: CC / FF: FF: FF: FF: FF: FF
add action = drop chain = input dst-mac-address = 01: 80: C2: 00: 00: 0E / FF: FF: FF: FF: FF: FF

most likely there is a leak in RB4011. I continue the study.

yes, my tests failed too. :(

already tired of RB4011. Let Mikrotik live on his own with this problem. I'll wait for 802.11ax. I'll see who first buys, what problems will experience. And then I will only order.

The new Mikrotik Audience uses same QCA radio for 2nd 5GHz WIFI (for inet distribution). Will be interesting to see if it also have problems.
If it works on Audience but not on RB4011, it's clearly hardware issue of RB4011 design. Could be as small thing as missing capacitor somewhere or having too long traces on PCB that sometimes produce glitch... but we will see after a few months when Audience will be more common.
But it's really annoying this issue is STILL not fixed! Seems like Mikrotik doesn't even know why it's happening...

FORTUNATELY... I only have one in the field and it has not exhibited this particular problem. Could the fact that I am in the US have something to do with it?

The reports of the wifi disabling itself... I never had that.

I have had other issues... but never that one. Could the fact that my routers are configured to UNITED STATES 2 or 3 or what ever help explain this?

For the problem to manifest you have to have no device connected to 5GHz wifi for a few hours. Then it "crashes".

The title is a bit misleading. The interface doesn't get disabled, in that you don't see it disabled (greyed out) in winbox.
It shows up/enabled fine in winbox/cli, but it doesn't transmit any SSID when the problem occurs. If you try to change any setting while that happens, then it gets stuck at "initializing" state and doesn't change until you reboot the device.

In my board that the issue occurs, I indeed use the SFP port.

The SFP port doesn't seem to play a role - I tested a single one with SFP and couple with standard default config setup with Ethernet-1 WAN and they were crashing equally bad ;)

I also have this issue, however it seems to occur randomly. Yesterday upgraded to 6.45.6 and had 5Ghz go out in less than 1 hour. After restart its ok again. Currently 5Ghz is working but the led under the device is on, so it should not be related?

Infact what is the led under the device for as in what does it indicate?

I have the same problem with 5Ghz WiFi too. I decided to completely disable the 5Ghz interface because every time it was working only for a few minutes and than the SSID disappeared and all devices lost connection. I had to restart interface. Really annoying. I do not use SPF port at all, so in my opinion the problem is not connected with it.
I am really disappointed with attitude of Mikrotik. I am waiting for the fix a lot of months ...

Thanks everyone for the input, thanks to those who contacted support@mikrotik.com and provided detailed information, and a special thanks to @TimurA for helping us with the debugging.

We've just released public beta with the potential fix (6.46beta59). The included fix not only improves 5GHz stability for RB4011, but also for cAP-AC, hAP-AC^2, Audience and other devices with IPQ4019, QCA9984, QCA9888 chips.

If you still encounter SSID disappearance for 5GHz interface, reboot the device and do the following:
1. Use WiFi analyzer software and take a screenshot of all nearby SSID's within 5GHz range showing each SSID channel number.
2. Generate supout.rif after 5GHz SSID disappeared
3. Enable/Disable or Provision the 5GHz interface
4. Use WiFi analyzer software and take a screenshot of all nearby SSID's within 5GHz range showing each SSID channel number.
5. Generate second supout.rif
6. Write an e-mail to support@mikrotik.com providing both supout.rif files, two screenshots, details about all the clients that were connected to the given AP (any interface) while the 5GHz SSID disappeared.

That’s great news! I updated my cAP-AC yesterday without problems, and after the 5ghz interface on my RB4011 died today I updated that as well. Both updates went fine.

Hello team. Thank you for update. 10h 5Gh work without falling, speed for local resources increase from 25-40Mb\s to 45-55Mb\s and it's more stable. But one question still remains: my "old" hAP AC get 50-55Mb/s on 5Ghz too, by LAN show the same results, so what is the reason to update on RB4011 from hAP AC and call RB4011 it the "best"?

I think I can get 70-90Mb/s on 5Gh after update hardware....

Those devices differ more than they match (like the company who makes them), especially in performance. This sounds like an issue with your host device (does not support multiple spatial streams or higher channel width), the configuration you're using, interference or many, many other factors. Please provide more solid data on your tests

Don't be so sure, test it for a month or so before claiming that.

The issue was with a buffer that was not clearing fully and caused the interface to "freeze". It also required very specific conditions and chain of events in order to happen, that's why only some people experienced the issue.

Sorry for the inconvenience caused

Colleagues, a question: maybe an attack is being made on your router (wifi)? Does someone raise a point with the same mac address and what else does it do?

After fixing in beta59, I only have micro friezes when roaming to another point and, on the advice of Reinis, I played around with the client disconnect timeout parameters. So far so good.

ps.
The only thing I don’t like right now is the performance of 5ghz, it has become lower. In the region of 250-320mbit/s, before it was more ~ 400-500mbit/s
