Wireless Networking • Re: 5GHz channels disappeared on hAP ax2

I was working through the various channels, testing each one with my mobile and on 5680, it started working and then said "failed to select channel"



And a key entry in the log: private-5g: radar detected on 5680/ax/eCee. This isn't always occurring butt might start to give some hint as to what's going on. If there are radar events (unusual, never seen before here but who knows), shouldn't the router try and find a different frequency when the frequency is set to blank/auto?

This is the result of testing with my laptop and Android mobile:

5180/ax/Ceee OK
5200/ax/eCee OK
5220/ax/eeCe OK
5240/ax/eeeC OK

5660/ax/Ceee OK
5680/ax/eCee OK
5700/ax/eeCe OK
5720/ax/eeeC FAILED

The mobile is unable to connect on that very last configuration which happens to be the one that auto keeps favouring. Now I know I can set the frequency manually, I'm more intrigued here why the mobile (and it happens my Android tablet) struggles with that particular configuration. Because it's not the range 5650-5730 as such as 5660 works. It's when the control channel is on 5720. Probably not Wi-Fi 6 chipset in mobile either as Wi-Fi 5 tablet struggles too.

I dropped the channel width down to 20MHz and went through 5660, 5680, 5700 and 5720. It's the last one that's problematic for sure. Could connect (mobile & tablet) on the first three but not last. Once again, laptop fine on all of them.

I'm going to dig out an AC router which I think I've got in the box and have a play on that.
