[RTW8822CE] failed to connect 5ghz wifi #242

Closed vtolstov closed 2 days ago

vtolstov commented 2 days ago

i have latest stable fedora, and rtl8822ce network card. Why i cant see any wifi 5ghz ap? if i'm create manually connection to my 5ghz hotspot it fails to connect. my macbook air succeseful connect to the same 5ghz hotspot without any issues (hotspot on mikrotik cap ax)

also i'm try to build module from this repo, but nothing changed - no wifi 5ghz

dubhater commented 2 days ago

Maybe your 5 GHz channels are all disabled. What is the output of iw reg get and iw phy?

vtolstov commented 2 days ago

this is from linux with realtek that cant connect to 5ghz

I'm not sure why it says "phy#0 (self-managed)". I don't get that with RTL8822CE.

What is the output of iw phy?

I'm not sure why it says "phy#0 (self-managed)". I don't get that with RTL8822CE.

What is the output of iw phy?

* 5500.0 MHz [100] (disabled) <- This is why you don't see your AP. It should work if you move the network to one of the channels which aren't disabled.

According to Wikipedia, channels 96-128 are not allowed in Russia: https://en.wikipedia.org/wiki/List_of_WLAN_channels#5_GHz_(802.11a/h/n/ac/ax/be)

hmm thanks, so i need to change country in ap and on linux ?

dubhater commented 2 days ago

You can change the channel or the country, but changing the country is probably not legal.

Big thanks
