Hello everyone,
as in the subject of the topic, after upgrading to 5.11 I've lost 5 GHz connectivity.
I had problems with it when using 5.9, and 5.10 solved the issue. After updating everything went back and I'm either only able to connect to a 2.4 AP, or 5 GHz up and down link speeds are very bad.
I tried messing around with the iwlwifi driver, who gets correctly loaded, in particular following what the wiki suggests here but without success.
What I've noticed is that by disabling 802.11n my 5 GHz AP disappears completely, and by enabling it my AP appears between the visible APs but when I try to connect to it, the connection hangs at "configuring interface" and then goes back to 2.4. With antenna aggregation on I'm able to connect but without internet access and by forcing bluetooth coexistence the connection is extremely unstable but at least I get slow up and down link speeds.
Is anyone else experiencing this problem? any idea how to solve it?

I had a similar problem. I was able to work around it by enabling WPA3 encryption in my router. I am not sure why that worked, but my connection is stable now, without changing any module settings. Bluetooth also works.
I had the idea to try this because I couldn't connect to any wifi network when I had enabled software encryption.

Sorry to necro this post, but I've been fighting this for months myself. I even replaced the AX200 chip inside today, same problem persisted. So I spent today going through everything.
If you do 11n_disable=1, it downgrades you to 20mbps wireless b, i think it is. But it's much more stable than nothing.
What finally solved it for me was:
switching to iwd
adding disable_11ac=1 to the module params.
I have a wifi 6 network, if that matters. Without disable_11ac, I was getting high ping times and unusable speeds.
I'm now pushing 200mbps each way, with ping times of 1-2ms to the router.
Hope this helps anyone else stuck with intel's awful drivers.
