Hello,
My new Mikrotik Hap ax2 router stopped working on the 5Ghz band after two weeks of continuous use.
I suspect interfereence from local radar or other 5ghz systems.
Using Winbox, I have been unable to change the frequency so as not to interfere with radar in the area.
I live in the USA and have set the router for “United States”.
Can someone please tell me how to fix this?
Sincerely,
dbjames
Could it be hardware failure? I know MT devices are known to be reliable, but since you say it worked for two weeks and then suddenly stopped, it sounds a bit suspicious. I suspect others on the forum would like to see your configuration to be able to properly help you.
Please share your config, so we can rule things out:

Leave channel.band unselected. It will figure it out on its own.
And manually specify the frequency to be used to avoid you get something subject to DFS.
FT settings are useless when you use different ssid.
AX devices support (and sometimes prefer) the U-NNI-4 frequencies … not every client supports those. If AP selects frequency not supported by client it’s ad good as not transmitting.
You can check which actual frequency uses AP by running
/interface/wifi/monitor wifi1
or in GUI by clicking wifi1 in list of interfaces and unfolding “Status”.
This works:
/interface/wifi
set [find default-name-wifi1 ] disable=yes
:delay 10000ms;
set [find default-name-wifi1 ] disable=no
It turns off the 5ghz, waits ten seconds and turns it on. Forces the dfs to search for a new frequency.

I thought it was working:
/interface/wifi
set [find default-name-wifi1 ] disable=yes
:delay 10000ms;
set [find default-name-wifi1 ] disable=no
[code/]
The above solution worked for about a week and then quit working.
No 5ghz for about a month.
I live in a rural area in Texas.
What do I do now?
Try lower channel width if it’s actually caused by a radar
Like 20/40 mhz
