Hello PPC users, I have ran into a little problem on my PowerMac G5 2,5 GHz, late 2005. You see, the Airport card appears to... disappear. When i start the computer: Airport is found and connects to my network. However, a pair of seconds later, it simply turns off. I go into the settings/network and try to reenable it; but to no avail. It does not want to switch it on. And if you restart or try to make a new Airport connection it simply states that there are no Airport cards installed. This is proving to be quite a problem as on one boot the Airport functions for about a minute (max), and on the next boot it doesn't. I checked the inards of it, but the card is sitting firmly, and no traces of any faulty wires or loose connections. I've tried everything and now im stuck, any ideas?
