I bought a MacBook for my wife last October 2007. At the same time we bought an Airport Extreme. My hope was that it would enable an ethernet connection to my G4 and a wireless connection to the MacBook. From day one we've experienced dropped connections.
Plugged directly into our D-Link DSL-320T modem both computers connect without a hitch. But that's not practical because we can only use one at a time. As a result the MacBook is barely used; and my name is mud.
My first post regarding our internet connection problems can be found at
http://discussions.apple.com/thread.jspa?threadID=1365188&tstart=0. Nobody came up with an answer.
I've spent days trawling the internet seeking enlightenment - but have found none.
In February I purchased an iMac. With this dropped connections persisted. But it did enable me to make use of Apple Care (in all the years since I'd bought and maintained IIci's and subsequent machines for work I'd not needed it). Apple Care UK listened and passed me up the support ladder to European HQ in Belgium. We worked together over two days, changing settings, doing tests, checking for interference, etc., etc., and got nowhere. Eventually they agreed to exchange Airport Extreme. The new one arrived last week. All software is up to date. We still have dropped connections.
Today I've checked my (Apple Care tuned) settings again, and again, have tried variations, have disabled all my Widgets, have rebooted, and have written pages more notes. When I started up today connection lasted just 2 minutes before being dropped. It gradually improved until it was hanging on for 9 minutes. Now it's down to 30 seconds.
I'm sure you're following this thread at 1 Infinite Loop in Cupertino. Do please indicate that you're on the case. There must be more to iLife than this.
+My network preferences are open and the colours are changing faster than traffic lights. As soon as Airport changes to green I'll post this.+
