HELP: WIFI poor signal after 10.3.5 update(i think)

[juanp]

I have a lyksys wifi-G installed 7 meters away from my room(desk). but there is a concrete wall blocking it so normally i get 1-2 bars of signal from my room. but early this morning i updated to 10.3.5 and after i restarted my comp i couldn't get any signal unless i stay right beside the lyksys ( i don't even get full bars even if i'm beside it). So i checked my dads tablet w bulit in B wifi card and was able to get 2 bars and more w my sisters G laptop in my desk. i'm not sure if it's because of the update or i have a hardware problem w my airport extreme. PLEASE help!! coz if no choice i have to place a long LAN cord all the way to my room.

Oh and i tested my broadband at www.2wires.com and only got 90kbps siting beside the lyksys while my dads tablet got 190-200kbps 5 meters away from the lyksys. Then when i used the lan cord i was able to get 150kbps. Is it the browser or there is something wrong w my computer?

thanks a lot for the help guys!

have you tried shutting down the Mac? Sometimes this works wonders. Also, try to check if your airport card is seated properly.

what is the firmware version of your linksys?
there is a newer version.try to check it out.
