5G network is not visible on 6.2.5 kernels

[KES777]

I tried to search 5G network, but only 2G available.

Linux work 6.2.5-060205-generic #202303110831 SMP PREEMPT_DYNAMIC Sat Mar 11 13:57:40 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

Which and how I can provide more debug information to resolve this issue? Thank you.

@KES777 I had this issue just a bit ago on 6.1.0; I resolved it by installing libelf-dev, recompiling, and reloading the 88XXau module.

@2l47 I have installed libelf-dev. I tried recompiling and installing once more without success. I can see TP-Link-5G network, I can connect to it and work. I do not see 5G network only from DIR-822.

I'm also having the same issue, and the weird part is that it seems that I can see them, but I can't get their SSID correctly, so I can't connect to them. When I run nmcli dev wifi list, this is the output (changed the BSSID just a bit):

This is the sudo lshw -C network
