Hi, I recently upgraded from a G4 to a dual 2ghz G5. I am having trouble getting on the Internet with the airport card installed. My g4 connected fine at the same house and network. I opened the computer and double checked the card and antenna we're firmly inserted. However, I disconnected it and was about to reconnect and try again when I noticed the internal antenna connection seems to be damaged. The computer recognizes the card and says it is on, but it cannot find any networks. My question is if I connect an external antenna on the back of the computer.. Will it override the faulty internal antenna? Or do the two have to be fully functional to work? I am 99% sure the pin and connection of the internal antenna is shot. I would like to know if the external antenna is connected and the internal is not, will I be able to connect to the Internet. My router supports b/g/n formats so compatibility isn't the issue. Any help would be great.
