bättre beskrivning av problemet:
"I'm also having a similar problem - I keep losing my wireless connection. To get it back, I have to Turn Airport Off, then Turn Airport On again
At first I assumed it was my Netgear DG834PN router, but I've just put my Dell laptop next to my 2 days old Macbook Pro (2.4GHz) and found that my Dell laptop still had a connection when my Macbook Pro didn't!
I was also having a similar problem with my Macbook in the past few weeks. When I lose the connection, the bars on my Airport icon still show there's a connection, but I cannot connect to my router. Then I can wait a few minutes and it will load okay again."
