I've moved on from the bottleneck issue (other thread) -- which means I can't stop focusing on the wifi channel issue.

I have reset the radio provisioning and recreated the wifi interface for 5ghz.

Tried 5Ghz N, AC, and AX

Left the Channel Width empty.

And tried all frequencies from 5160 to 5885 in 20mhz increments. The only 2 that do not produce the error are 5180 and 5745 (even with the channel width left empty).

This is really crazy.

Anyone have any idea what could be going on?

Normal MT wifi experience.........Why I use another vendors product for wifi. I mean it will work well once you figure it out, but for me personally not worth the stress to get there.
I am also lazy and dont like dealing with capsman.

What error are you getting ? radar detected ?

But I must agree with @anav here, with other vendors you will get much more smoother Wi-Fi experience. With Mikrotik it's just frustrating sometimes to get Wi-Fi to work right...

"the error". everything clear for anyone here.

Sorry about not identifying the error.

I started a new thread because it was a new topic that the original thread morphed into, from here:

viewtopic.php?p=1065645#p1065645

The error is:

"NO SUPPORTED CHANNELS"

Upon further playing around, I discovered that if I change the county to RUSSIA, I can enter pretty much any frequency I desire.

For example, any frequency allowed in the United States can be entered (5500, for example).

So, at least we have a workaround.

well, your issue is all about "skip-dfs-channels=all".

No experience with Russia, but maybe they don't have DFS regulation and that's why it works for you.

Illegally setting up WIFI in your country is probably not the best solution.

In the heart of an incredibly RF and people dense city, in a huge apartment building, I don't have a choice but to use DFS channels.

Nothing illegal about using approved devices at 5500Mhz in USA.

I agree, however, a better solution would be for it to work as it is supposed to.

Well, then set this to skip-dfs-channels=disabled ... only then will your ax3 try to use DFS channels (note the wording of property, it includes "skip").

Wow! The double negative ("skip" and "disabled") confused me.

This might be an easy fix (and worth it).

Perhaps the field should read: DFS-CHANNELS

and the choices (options) should be:

USE-ALL-DFS-CHANNELS
USE-AND-SCAN-EVERY-10-MINUTEs
DO-NOT-USE-DFS-CHANNELS

Thank you for clarifying!
