hp

I have a HP dv2745se laptop. I always had Ubuntu with the Native Windows Vista and Wifi worked fine. Suddenly my Ubuntu wouldn't load anymore, I tried fixing it for a week and eventually I formatted its partition and just installed Ubuntu 12.10

This laptop has a Wifi switch that works fine in Vista disabling / enabling the wireless connection. HP Wireless Assistant in Windows say Wireless is on. However, whenever I log in Ubuntu the Wifi button is always orange (disabled) and Wireless never works.

I had this problem once when I had Ubuntu 12.04 and I fixed it by verifying in Windows that the Wireless Assistant showed the Wireless LAN in "On" mode. However, the same does not work now.

I've seen some possible solutions that involve updating the firmware with apt-get. There comes my 2nd problem, my network adapter card is not working and thus I have no internet at all.

Any suggestions? Thanks!

I know that Ubuntu +1 questions are frowned upon, but this I believe is a fair exception.
