I installed ubuntu Os 22.04 LST on my notebook. I have no wifi drivers. I see an error:
No Wi-Fi adapter found
I was reading similar questions and tried command
lspci -knn | grep -iA3 net
Network Controller [0280] Device [0b48:7922]
...
Unassigned class [ff00]: Realtek Semiconducter Co., LTD RTS525A PCI Express Card Reader ...
What driver should I install?
My laptop model RedmiBook Pro 15 Ryzen Edition Laptop: AMD Ryzen 7 7840HS
UPDATE
Tried command (moved binary file to my PC with help of usb)
wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && chmod +x wireless-info && ./wireless-info
Result
