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 : 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.
