hello....
i recently installed arch linux in my laptop.for installation purpose i used usb tetherin from android. after installing my wifi card needed a firmware, and i set it up as said and it was working for atmost one day.Now wifi is connecting, but network is extremly slow. when using ping on 8.8.8.8 it sometimes show " host not reachable.". when using ethernet it is working fine. last thing i remember before the problem was creating an account for kde wallet.
someone please help me with this problem....
