networking - WIFI blocked - Blacklisting blocks WIFI for dual boot - Ask Ubuntu


i dual boot linux , windows on computer. have gone linux mint ubuntu. wifi isn't instantly compatible linux. used work linux mint (which knowledge builds on ubuntu) write "blacklist acer_wmi" /etc/modprobe.d/blacklist config.

however, run command in ubuntu locks wifi os:es. is, ubuntu finds no wireless networks, rfkill list lists bluetooth, and, in windows, wifi "option" greyed out. correcting file mentioned above doesn't help. actually, have format hard drive , boot in legacy mode have computer find wifi again.

i have no idea how begin troubleshooting problem.

any appreciated!

you can fix running

sudo tee /etc/modprobe.d/blacklist-acer-wmi.conf <<< "blacklist acer_wmi"

reboot after it.

that create file config. alternatively can add line blacklist.conf file.

you may need reset bios defaults.
