[Kernel-packages] [Bug 1861278] Re: RTL8821CE - 5GHZ networks not working
I have news: I can connect to my 5 GHZ network now. I am not sure why though. (1) I changed the 5GHZ channel (2) I changed the frequency band from 80mhz to 40mhz (3) Maybe the last driver update from March did something? Here are my current outputs (I don't think there's much change though): dmesg | grep 8821 [2.503406] rtl8821ce: loading out-of-tree module taints kernel.
