This is just a guess, but it may be the ExpressModem drivers are not installed. That's the problem that I had on mine, anyway... Go here: http://mirror.apple.com/Mirrors/Apple_Software_Updates/English-North_American/Macintosh/Networking-Communications/Apple_Telecom/ Download Telecom_3.1.3_1of8 and Telecom_3.1.3_2of8 . If you do a custom install of just the ExpressModem drivers, then those two images should be all you need. Then reboot, and you should be good to go. I could be wrong, though... Regards, Jim Thomas
