View Full Version : [ubuntu] Wireless problem - HP DV5-1015EA, Intel 5100 AGN

I have a wireless problem with the latest Ubuntu. I had been using Hardy briefly, then some of the pre-release versions of Intrepid on a HP-DV5 1015EA laptop. My wireless card didn't work with Hardy (hence moving to early intrepid versions as soon as possible), and initially it worked with Intrepid but then one of the upgrades did something funny and I kept having to run


sudo modprobe iwl4965

to get the wireless to work.

Now, it has stopped working completely, although I can connect to wired ethernet network but it is extremely awkward.

I've tried everything I could find on any thread on the internet about intrepid wireless problems but nothing works. I have no network manager applet to even look at the status of networks etc.

I have an HP Pavilion dv7 running a 8.10 with this card in it. Everything WAS fine for a very long time. Then I rebooted, presumably after some updates, and now I get the same sort of thing. Everything looks like it is fine, except I don't see ANY access points in my list anymore.
