Wireless problem

[atomichybrid]

Alright I have this whacky problem with my ubuntu 10.10 wireless. At times it connects like normal and its good, but there are times when it doesnt connect even when I can see it on the wireless list. It fails to connect and then sometime during the day it works again. What is the problem? its like it has a mind of its own. I'd rather use the wireless since the cable is useless and the router is in the middle of no where so its kinda of bad if I use the cable. If there are any fixes I would appreciate it.

Cheers,
P.S. Ive upgraded to ubuntu 11.04 but didnt like the Unity interface and using the gnome version has so many bugs in it I just couldnt be bothered to go through all that and reverted to 10.10.
