Is your home router set to be backwards (802.11b) compatible? if it is stuck at 802.11g (54Mbps) it might not be able to see it as it won't talk to it due to the slower speed.
Also, is the SSID Hidden and you don't know? Did you have to program your other machines to look for that SSID?
Another thing I got to thinking is that you might have broken the internal solder/trace on the antenna and therefore may not be able to receive anything due to the antenna being broken.
Check a few things, you may try entering the network manually and see if it works. if it connects, you may simply be hitting a bug in the software. It's rare, but as we all know, bugs happen and developers are expected to count for anything and everything (which is extremely hard)
