Archbang can't connect to wireless

Last week I tried Crunchbang 11, it couldn't connect to wireless. Yesterday I removed it and installed Archbang from CD (final 2012 version). Everything was working perfectly, when I did pacman -Syu and rebooted, Archbang stopped detecting my wireless card so I bet that the new Linux drivers aren't compatible with my HP Pavillion G. It's not the first time that I've seen drivers incompatible with my laptop, I've seen it last week with Crunchbang, and I've had graphics issues with every Linux that i've used on this laptop. What I would like to do is simple. I want to downgrade the Archbang wireless drivers, I want my original drivers back, the ones installed in the final 2012 version (I have the CD, can I use it?), and then I don't want to allow pacman to upgrade my wireless drivers, so next time I run pacman -Syu, I want everything to be upgraded except my wireless drivers, and if possible my graphic card drivers. You see Ubuntu 12.04 works great, 12.10 doesn't work at all, I don't even see the login screen, even with nomodeset. I don't want that to happen, and Archbang is a rolling release so I don't know if the next time I upgrade my packages I'll face some issues, I want to allow pacman to upgrade everything, just don't mess with my graphics and my wireless, that's it.
