Found possible bug:

When you add subnet into "available from" field for SSH service, under IP Services...SSH becomes inaccessible, even if PC is in that subnet.

Code: Select all

ssh_exchange_identification: Connection closed by remote host

It seems only to affect SSH though, for limiting access to http, https it work just fine.

Basically happens only: on Hap Ac2 at AP mode (full L2 bridge), still limiting SSH should work, IMHO...

bug.
I choose in settings "IP.IPsec.Peers " certificates for the server and remote server. But after some time, the certificates disappear and become "none". I use the method: rsa-signature-hybrid.
why does the certificate disappear? Sometimes it happens that the server and the remote server - certificates themselves become the same.

Bug 2
if you use https to connect (together with the certificate), sometimes there are delays of 3..5 seconds when opening various settings. all open quickly but then go to what that tab to view the settings and there is a delay for 3..5 seconds. nothing shows for 3..5 seconds. another problem with https is that it shows different settings compared to winbox.

this is possible due to access to jsproxy, it is not.

There's something really strange going on with DFS. I just got a new INTL RB4011 and set it to "united states" regulatory domain with "manual txpower" and 80Mhz channel. The AP is getting stuck in radar detection half of the time (even though I'm 100% sure there're no weather or military radars around, since I live practically in the forest). For example now (see screenshot) it was in "detecting radar" mode for 10 minutes.
It's simply not acceptable for me and AFAIK there's no way to disable DFS while still keeping the scanlist of the regulatory domain (or is it?).

Use manually non DSF channel (5200, 5220 or 5240). Problem solved.

@kiler129 I had this problem. After change change:
-Frequency Mode: superchannel
-Country: no_country_set
-Channel Width: 20/40/80MHz eeeC
my problem is solved. Lets try

You can't use anymore country settings and frequency mode different from regulatory domain.

hello support!
Could you give us more information about this changelog entry?

*) wireless - improved stability for 802.11ac;

What have been changed? Any improvement in NV2?

Thanks!

Would like to know as well. My RB4011 keeps disabling 5ghz WiFi after a few days (see graph). Only a reboot can bring the WiFi up again. Wondering if this has been fixed

I am having the same problem.

mikelaurense - Does interface actually gets disabled? Or it becomes inacessible? If it disabled, then someone has done that manually. Please provide supout.rif file tp support@mikrotik.com. Make sure that file is generated while interface is "disabled".
...

I'm facing the same issue as mikelaurense. When this happens for me, I can see that the wifi interface is shown as "S" instead of "RS". When going in the settings, I can see "Enabled" is still checked but the interface is not shown as "Running". The wifi network in itself becomes inaccessible, as in, it doesn't appear anymore when scanning from another device. There is nothing in the logs about the interface being disabled. Disabling and Enabling again the interface does not fix the problem. Rebooting does.

This happens every few days seemingly at random hours, always during the day when nobody is home (virtually no traffic on wifi) or at night one I sleep (virtually no traffic on wifi).

Me too

I launch the terminal, I create the rule.
In the parameters an intentional error, the rule applies.
I look through the winbox, I see a new error parameter perouting.
This is normal ?

This is normal ?

It is. Absolutely. You have simply added a rule to a custom (user-defined) chain named 'perouting' that you can now jump to using 'action=jump' rules.

And, by the say, this is in no way version-specific, so in the future please refrain from posting such questions to version-specific threads.

After contact with Mikrotik support I changed channel width to ‘20/40/80 MHz XXXX’. This does seem to improve stability, although it did happen once or twice again since changing it

LTE bell on any phone - kicks wifi on RB4011, any channel from 36-161!

Please see how shows "Bytes" in IP-mangle. There are non sense data.
Please fix it in next release.
This problem persists over many versions

Thank you

abrandecky please generate and send supout file to support.

Which one is next stable release? v6.44?

My 750Gr3s seem to show a memory leak in the proxy. With proxy disabled the memory usage is around 42mb. If you enable the proxy but don't send any traffic the memory consumption stays at 42mb. As soon as you open the web proxy interface in winbox the memory consumption jumps to 64mb (still no traffic via proxy). As soon as any traffic flows via the proxy the memory consumption jumps to 102mb. At the same time, if you go and look at the proxy it says Total RAM Used: 996KiB. So something somewhere is leaking close to 60mb. This did not happen before on 6.42.7 which is the version I upgraded from.
Does anyone know how to rectify?
I'm afraid of upgrading my 941 and 952 devices as they don't have the 60mb for the leak and most of them are remote (like 20 hour plane ride away)

"20 hour plane ride away", my god Please don't. Stay on bugfix or Long-term how it's called now.

New version 6.43.11 has been released in stable RouterOS channel:
