Hi, I have a PowerBook Pismo G3, and I have a wireless PC card. When I plug it in the Airport adapter, it detects it in the Menu Bar by showing a card icon, but the Wi-Fi internet doesn't work! It wouldn't do anything else. When I click on the icon, it shows the following three: INTERSIL HFA384x/IEEE Power off card Power off card is the only useable choice in that list. The card is an eSmart 802.11b wireless card. HOW DO I GET IT TO WORK!?!?!?!?!?
