Hi - I appreciate all the AT&T techs telling us to go through all these steps, but it is obvious from the reading and other sites that the problem is an incompatibility between 2WIRE and Macs. My son has a Mac. Our DSL works fine with all our PCs and with any guests who come with PCs. But when he comes home with his Mac, the trouble begins. The 2WIRE Internet light turns red for a bit, then it reconnects. All other computers have to shut down browsers and reopen. Even the computer which is hard wired to one of the ethernet ports shuts down as well, so it does not just affect the wireless connections on the modem. Reading elsewhere says that the 2WIRE doesn't even support Macs. If that is the case, what was AT&T thinking when recommending it for their DSL installations? If something just needs to be tweaked on the Mac or on the 2WIRE, someone needs to be able to post what the tweak is. I hope AT&T can come up with a better answer than clearing cache or reinstalling something!
