I have had this computer running on the same wireless network continuosly for almost 3 weeks, until yesterday. i had taken it to a friend's house to do some recording and when i got back home and hooked it back up, my wireless networks were not detected. i reset my D-Link router a half dozen times, but i don't think it is the culprit of my problems (the other powerbook in the house picked it up no problem still). I tried manually setting up the connection in Internet Connect utility but all i get is an error. i took my laptop to work with me where i know there are two more networks, one of which is unencrypted, and still no dice. anybody got any cool tricks i can try?
