I am facing a issue after install Ubuntu 12.04LTS on My laptop (hp Probook 4540s). My wireless LAN and Bluetooth is not working. I got a list after put this command in terminal:

$ lspci -nnk | grep -iEA3 "(wireless|network)"

Result:

Network controller [0280]: Ralink corp. Device [1814:3290]
    Subsystem: Hewlett-Packard Company Device [103c:18ec]
    Kernel driver in use: rt2860
    Kernel modules: rt3290sta

I am not a expert in Ubuntu.So kindly help me.

I have a partial solution! This is based on https://github.com/loimu/rtbth-dkms

This will install a compatible driver:

sudo add-apt-repository ppa:blaze/rtbth-dkms sudo apt-get update sudo apt-get install rtbth-dkms sudo modprobe rtbth sudo rfkill unblock bluetooth

With that, I'm able to scan for Bluetooth devices and connect to them. Sadly, I can't get it to transfer data!

I had the same problem. Fixed it by removing the Ralink wifi card and replacing it with an Atheros card from a scrap Laptop. Now all works great in Linux, Backtrack and Win7 BikerMike
