You could be correct.  Not sure what cards they put in the mac so I 
don't know if it is a sensitivity issue, it could also be a driver issue 
on the mac and the possible new router.  There use to be a problem with 
senao cards and D-Link routers.  For what ever reason they would always 
associate with the D-Link regardless of SSID.

Probably an easy check would be to borrow someone else's router, 
preferably not a linksys, and see if you can get it to work at your place.
