Ubuntu 20.04 No wifi adapter found Lenovo G5
By Jessica Wood •
I bought a new laptop (Lenovo legion G5) I installed windows & ubuntu in dual boot. On windows side my wireless adapter work as well, but on Ubuntu I got this message : No wifi adapter found.
I tried many solutions, I found this one wich is very similar to my laptop specs, but unfortunately when I execute this command :
cd rtw89 && make && sudo make installI got an error message :
cp: cannot stat 'rtl8852au*.bin': No such file or directorysudo lshw -C network
