I recently bought a new HP DV6-3118SA laptop, but I am having a very discouraging problem with wireless LAN. It simply doesn't work!

Could you please help me with this?

This is pretty much the defacto set of instructions on getting the 3090 to work properly. I had some trouble with them with 64 bit, but these instructions now seem to work in all cases. You may need to remove and re-install the package on kernel updates on occasion, so make sure you do them where you have a wired connection.

Thanks very much! –  Rafid Mar 12 '11 at 11:29

Try adding this PPA for the Ralink 3090 driver to your system.

sudo add-apt-repository ppa:markus-tisoft/rt3090

Then; sudo apt-get update

Followed by; sudo apt-get install rt3090

Thanks very much, but there seems to be more instructions in @Nerdfest's answer. –  Rafid Mar 12 '11 at 11:30
    
@Promather - agreed, hope it helps to fix your problem. –  Mark Rooney Mar 12 '11 at 11:40
