So, I upgraded my RB2011UAS-2HnD from 6.28 → 6.37rc11, wifi don`r work, interface wlan1 not in Running state.
downgrade to 6.36, same result.
downgrade back to 6.28, wlan1 now in Running state but no wifi available.

Always read the releasenotes first!

You probably need to install some wireless package and enable the wlan manually.

4

did it. When you upgrading 6.28 → 6.36 ROS ask you to manually disable and uninstall wireless-fp.

Now that`s how my package list looks:

[admin@MikroTik] > /system package print
Flags: X - disabled

0 lte 6.36
1 system 6.28
2 advanced-tools 6.28

6 hotspot 6.28

And you don’t see any wireless interface? Have you updated the firmware too?

I have seen that on 6.37, on first time upgrade, the wireless package is disabled and the configuration is lost.
If you have a configuration backup file on the device?
If yes, enable the wireless package, restore the backup it and reboot. This should fix it.

didn`t touch firmware, it was ok with 6.28 and now I downgraded ROS back to 6.28.

I can see wireless interface, and it shows as Running(see code in first post) but my mobile devices can`t see mikrotik SSID anymore.

In my case looks like configuration wasnt erased, and yes I disabled wireless-fp, uninstalled it, installed 6.37 with package wireless. Now I downgraded back to 6.28 and configuration looks ok. I'm not pro mikrotik guy` so I guess I just missed something trivial.

As of diagnostics, scan works well:

Does it run in Ap bridge mode? Maybe you should reset wireless settings and set up wlan again…

What do u want to achieve Station or AP? I can see ur device mode = station.

thx all, yes station mode ruined my morning today ^^ I reset device and reconfigured it, everything looks ok now.

I also lost wireless interface on upgrade from RouterOS 6.37 rc 5 to rc 12 and 15 is also missing. Try with downgrading fw 3.33 to 3.24. same result. This is on RB 2011UiAS-2HnD. On 2011UAS-2HnD wireless working normal with RouterOS 37 rc 12 and 15. Same firmware on both.

Never use release candidate versions on productive devices. They are for testing purposes only and are not expected to work reliably.
