Sorry for not following the forum rules thoroughly, but I am in a very urgent situation. Someone I know: asked me to install linux to a brand new HP notebook; is leaving the city in 24 hours; is going to need the computer during a trip for work. So I did (Mint was my choice), and as usual, everything is working well, except for wifi.
The only thing I did to solve the problem was installing https://github.com/lwfinger/rtlwifi_new/ driver (just installing) (from this post: http://askubuntu.com/questions/590414/w ... untu-14-04), which didn't help.
Right now I am sitting next to a wifi router with ethernet cable plugged in. When I hit "disconnect wired connection" in the tray, but leave the ethernet plugged in, the wifi seems to work, but antenna (in the tray) is low (though the distance between the notebook and the router is less then a metre), the speed is low, and when I ping google.com it loses packets.
Some code.
