My wife has an iBook G3 500mhz with 320mb of ram. She is having trouble with the airport card that is installed in it. I have a 2.4ghz wireless access point in the upstairs of my house (next to my main machine) which is sending the signal to a 2.4ghz bridge in the downstairs. House is wood frame. She is having problems connecting to the wireless network. When she can actually connect, she has to be right next to a wireless router and even then it doesn't work sometimes to connect. Is the airport card going bad in this? Is it possible that the antenna has gone bad or has a kink in it or something?
