I have an HP Pavillion dv6000 that is a few years old that I did a data recovery on some time back and in return the guy gave me the laptop. I run a box with BackTrack and a Box with Fedora so I thought I would give Ubuntu 10.4LTS a try.
I had everything working beautifully for a few weeks and then yesterday, out of nowhere the wireless adapter just disappeared. What I mean is that all of a sudden I was no longer able to connect to my wireless network (iPad, Windows systems, and other Linux systems can still connect) and an ifconfig shows no wireless adapter in the output. I just see the loopback and two ethernet adapters....no wlan0 as before. I have deleted the network from network connections, tried forcing the adapter up with "sudo ifconfig wlan0" but nothing has worked. Yes the wireless switch is enabled.
I am not MAC filtering on the router so I don't know what else could be causing this. Any ideas anyone?
