And booting the previously kernel (5.8.15), your wifi works just fine?

no same issue. wifi connect and disconnect after a few minutes

Hello,
any solutions to this issue…

Same symptoms in fedora 32. Sometimes stopping and restarting Network Manager allows wifi connection for a few minutes sometimes it does not. nmcli shows available connections, but system fails to connect. The failure also occurs in Ubuntu 18.04 on the Lenovo 730. The 3rd partition is Windows 10 and failure does not appear to occur there.
Suspect driver
sudo dmesg | grep rtw_8822be
shows some failure mode:
1980.854677] rtw_8822be 0000:6c:00.0: firmware failed to restore hardware setting
[ 1990.902116] rtw_8822be 0000:6c:00.0: firmware failed to restore hardware setting
[ 2040.886241] rtw_8822be 0000:6c:00.0: firmware failed to restore hardware setting

wired connection and then disconnecting seems to fix the problem until the next hibernation of wifi or reboot.

any ideas?

Have you updated fedora32, because mine had same problem with rtw_8723de, but after I upgraded my system sudo dnf upgrade --refresh, everything is fine

I have a new twist on the issue, now only the 2.4 GHZ won’t connect. I verified that Windows 10 can connect at both 2.4 and 5 GHZ. I did update with sudo dnf upgrade – refresh yesterday and there were updates… I reran today and the result was “nothing to do.” Also the dmesg included on at least one occasion a reference to H2c.

Also the latest output looks like it shows multiple attempts to connect at 2.4 then the successful connection at 5 GHZ.
