Connectivity Problems

I am surprised that there is so little posted about connectivity problems on this forum. The Communities section of the Apple Support site as many threads dealing with this. I have a three-week old 17" MacBook Pro running OS 10.6.2 that frequently disconnects when inactive. I can sometimes get back on line with a Restart, but at other times it's more complicated. I've spent hours on the phone with Apple technical support and have had my Airport card replaced. Nevertheless, it continues to happen.

I'm really puzzled that this apparently doesn't afflict more MacBoook Pro users on this forum

 

That's one theory discussed on the Apple Support forum, but it's very unlikely. I use the latest version of Airport Extreme. My wife has an early version of the MacBook Pro running OS 10.5.8. Her computer uses the same router as mine and never goes off line.

I just can't help wondering why it doesn't seem to happen to posters frequenting MacRumors when it's such a prominent topic on the MacBook Pro section of the Apple Support forum
