I just bought and correctly installed a working airport card to my iBook G3 (M6497) I checked and the card is being recognized and says it's on. However, it can not find any wireless networks automatically. I tried entering the name of my network manually, but it says "There was an error joining the AirPort network "NameofNetwork"." "Try again" "OK" The router doesn't have any security on it and it is compatible with 802.11b. I bought this iBook from a friend who says he could never get an airport card he bought a while back to work either. Any ideas on how I can get this to work? Thanks so much!
