I was just curious if this had happened to anyone else. I have about a 1 month old Powerbook 12 inch and I have had great WiFi reception. I have an Airport Express at home and it has been great. Until about three days ago. I troubleshooted everything with the Express until I decided to take a look at the Airport Extreme card in the Powerbook. It was factory installed so I didn't think it was the culprit but it was. The antenna cord was nicked through the sheilding down to the bare wire. I taped it up and everything was fine. It was right at the turn and I guess the corner of the card was rubbing on it or something. Anyone else with this problem?
