I'm new to this forum so I hope I'm explaning this issue correctly.. I have a Powerbook G4. It doesn't have an internal wireless card so I bought a Linksys wireless adapter to plug into the side of my computer when I first got the computer. It worked fine for years. I recently reformatted the hard drive and now when I insert the wireless adapter it no longer will allow me to connect to the internet. I'm aware that Linksys doesn't have drivers for Mac users so I'm confused as to how I got it to work in the first place. I don't remember installing any third party software, but I may have, it was a few years ago. Does anyone have any suggestions what I should do to allow me to use my linksys card in my Mac? I've heard of Orangeware but I'm not sure if that's the solution. The adapter is a WPC54G. Thanks for your help! Oh one last thing, when I plug the card in, an icon appears in the top right corner that shows something is plugged into the port but doesn't allow me to click on it and search for wireless connections.
