Wifi 5Ghz not working despite 2.4ghz working (MEDIATEK MT7921 802.11ax)

Post by Shoset »

Hello !

I have a bit of a problem, my wifi 5ghz is not working despite my 2.4ghz working. I tried multiple things to make it work and weird thing happend :

I reinstall Linux 3 time for now, everytime when I try the demo mode, just after installing, the 5ghz is working well, for like 10min testing youtube and speedtest etc... ! But everytime I reboot, it is not working anymore...
I switched between 4 kernel, 5.15.91 / 5.15.97 / 6.2 / 6.5. The first time I installed the 6.2, just after installing it (not activated yet), the 5ghz worked, for 1min then internet stopped working, I could still connect, but no internet. So I reboot, and I couldn't connect.
I did disable the automatically connect to 2.4ghz to not have this weird back and forth, the first time I did it, the 5ghz could connect, but same as the kernel, after 1 min, no internet, still connected.
Now, doesn't matter which kernel is active or if i disable the connect automatically, the result is the same, I cannot connect to 5ghz.
And something "Weird" is happening now, if I try to connect to 5ghz, and that it fail ( always ), and I click on the 2.4ghz, it will connect, instantly, I mean INSTANT, like not even half a second of waiting.
I disable the power management too, didn't change anything.

The 5ghz work on windows. So no problem of card I guess...

I am out of idea. Here is my info.
