My wireless internet on my laptop is working fine. The wireless for the desktop was working the other say but today it isn't. I'm using PCLinuxOS '07. The wireless card is picking up on the networks in the surrounding area, including mine, however it won't connect now. it stops at "requesting a network address on interface ra0" (DHCP Protocol). All settings are same on both computers, however one is working and the other isnt.please help.
