I have two I-macs with Airport cards in each of them. I recently installed ADSL which I connect to the Internet with one of the Macs. I tried to connect the other Mac to the net via the card with no success. So then I paid a Mac dealer to succesfully configir the machines for me. A few weeks later an ex-employee played with the settings on the I-mac connected to the modem and now Airport will not work on the the client machine. Will things work better if I buy a base station, or will I have the same problems as tring to get each card to talk to eachother? Where can I find Airport card-card setup information for 10.3.3?
