I installed Kubuntu 13.10, with the 3.11.0-14 kernel, to a HP ENVY m6-1310sa laptop. My wireless connection was unreliable; it frequently disconnected and could reconnect only after reloading its driver in the kernel:

modprobe -r rt2800pci
modprobe rt2800pci

The wireless hardware was a Ralink RT3290:

lspci -nn | grep 0280
03:00.0 Network controller [0280]: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe [1814:3290]

Updating my kernel to 3.12, a known fix for this wireless card, introduced a different problem; the display driver failed. I saw a command line at boot.


resulted in a "no monitor" error.

My solution, and it may not be the best one, was to downgrade the kernel to 3.6.11-030611-generic, in the usual manner. i.e. wget the debian packages for v3.6.11-raring, install the kernel

  dpkg -i linux-*
  kate /etc/default/grub

Change the default kernel, by replacing




Updating grub,


and finally rebooting.
