[Ti] signal strength discrepancy

[Erik Gaderlund]

Now that were talking about airport/WiFi, I wonder if anyone has any 
ideas of what's been happeing with my parent's iMac.  They have a 
Proxim wireless/router hooked up to their RCA cable modem, and within 
the last couple of months the iMac can't get a constant signal (the 
router is not more than 1-2 feet from the iMac.  Watching the signal 
strength in the Airport app in 9.2.2--it jumps from high to nothing, 
assigning and re-assigning IP addresses.  We now have it hooked up by 
ethernet to the router so things are working fine.  I pulled and 
reseated/reattached the airport card and antenna, but, the signal 
still bounces.  When an iBook or TiBook is brought in they have no 
problems getting a signal and connecting to the network.  I did some 
searches on many sites and couldn't find anything.
