hey all

i have been trying to find a wireless nic for my laptop, that is very well supported in ubuntu/linux. i currently have a 3945 intel wireless card but none of the fixes out there have done anything for the severe lack of bandwidth just in my local network, transferring files makes me want to tear my hair out. I am really happy with ubuntu and have been an on and off linux user for about 6 years now. i would like to stay but this is really frustrating.

specs
dell e1705
2 gig ddr2
60GB
intel D/C 1.6
nvidia 7800 Go

thanks
