I just got a new Linksys wireless g notebook adapter. I installe the drivers and set it up with my linksys wireless g router. i can never get a signal over 7%. I tried changing the channels but it didnt work. The connection is very skippy, but I can still manage to play a first person shooter! Anyone know how to fix this problem?

Router model - WRT54GS
Notebook adapter - WPC54GS

Thanks
