I don't really know how to get into much more detail than the title has provided. I'm on a new HP Pavilion 15 and running Linux Mint 16 x64, but the wifi keeps dropping almost immedi ately (<1 min) after connecting and then doesn't allow me to reconnect. I'm dual booting windows 7 and it has no issues whatsoever with the wifi. Please request any additional information and I will provide it as soon as possible.

Can you post the output of lspci -nn | grep -i net? – MariusMatutiae Jan 9 '14 at 13:45
    
Updated, please take a look. – Brad Jan 9 '14 at 13:51
    
Also post the output of dmesg | tail -n 20 just after the wifi disconnects please. – terdon Jan 9 '14 at 13:56
    
MariusMatutiae's solution seems to have worked, thanks though. – Brad Jan 9 '14 at 14:27

The support for your wifi card, Ralink Rt3290, is still experimental, in Linux. You can see it here. Still we can try this as follows: go to an empty directory, and issue these commands:

    sudo apt-get install linux-headers-generic build-essential linux-firmware
  wget http://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.12.2/backports-3.12.2-1.tar.bz2
   tar xvf backports-3.12.2-1.tar.bz2
   cd backports-3.12.2-1/
   make defconfig-wifi
   make
   sudo make install

Shutdown and reboot, hopefully it will work.
