Thanks for that Dale, it sounds a lot like the C.U.D.A. reset switch on the older Power Macs. I find the Knowledge base documents so superficial and Apple stupidly secretive to the extent of absurdity. I think the Base Station I bought 1 month before the announcement of Extreme also infuriating. It screws up Internet Connect in my Dual Gig when disconnecting. No problem with the Internal Modem. Also when a DMG has been half downloaded and then another is downloaded and installed the idiotic OS refuses to allow the DMG to be put in the trash to boot. Still those are problems that Apple won't talk about or fix. Minor gripes. Paul
