FYI : Odroid N2(+) no wifi security on rolling build 5.15

[Walter Zambotti]

Using a Realtek 8821CU Bluetooth + Wifi USB adapter.

 

Working fine on stable build jammy with kernel 5.10.123. (current)

 

Using the Armbian->Config->System->Other and selecting the latest 5.15 kernel.  System reboots and confirm kernel has been updated and chosen.

 

Wifi hotspots are all seen but fails to connect and repeatedly asks for password.   Security is WAP2 personal.

 

Setting the kernel back to 5.10.current reverts to Wifi working as expected.

 

I will try the 5.17 kernel and report back.

 

I have seen this before on other Deb distros.  From memory this is caused by a missing/outdated kernel encryption module or wpa_supplicant.  However don't quote me.  It was quite some time ago.
