I've got a B&W G3 400 w/10.2.8. I purchased a DLink Wireless G Network PCI card. It didn't work. It was cheap after rebates, so I didn't really expect it to work. After more research returned it and got a Belkin Wireless G PCI, hoping it was going to work. Well I didn't read far enough down the forum and letting me know that they changed the chipset. Well after more research, I was lead to believe that I could use the Ralink driver, since it has that chipset. I downloaded it and my sys. prefs. noticed the card but it wouldn't connect. The driver didn't have any information to go with it and I couldn't figure out how to operate the driver. So after more reading and searching - Several folks used a Motorola WPCI810G. Comments said it was plug and play with Airport 3.1. After installation still nothing and it doesn't even show that its in the computer under the Apple info. The light on the card comes on, so I know its seated correctly. I put it in several of the other pci slots. I figured maybe it's 10.2.8. I installed 10.3, still nothing. I pulled the protective shield off of the card and it has the Broadcom chipset. I even downloaded the trail version of Orangeware. I tried everything I can think off. Any suggestions would be greatly appreciated.
