5.8.0-63 Breaks Wifi on RTL8822BE

[ndst]

After upgrading to 5.8.0-63 the wifi card RTL8822BE can still be seen, but wifi networks cannot be found. If the nvidia driver 470.57 is installed the wifi card is no longer found.

lspci | grep -i realtek:
07:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8822BE 802.11a/b/g/n/ac WiFi adapter (rev ff)

Thank you.

Hello ndst,

Groovy 20.10 has reached EOL, and so has the HWE kernel in Focal 20.04 based on the 5.8 kernel. Could you please update the HWE kernel to the latest 5.11-based version (5.11.0-25.27~20.04.1) and check whether the problem persists? The easiest way is to update the hwe meta package (likely linux-generic-hwe-20.04).

Hello,

I updated to a 5.11 version and it was working ok for a while. I recently updated to 5.11.0-38-generic #42~20.04.1 and wifi is no longer showing up. What can I do to fix this? Thank you.
