Anyone here having problem with the AirPort?

Any MBP owners here having problem with the AirPort? It disconnects itself quite frequently, especially when idle.
At first I thought maybe it shuts down itself to save battery, I thought it's an energy saver feature, but there is no
such option there to turn it off, and I left my computer on all night last night, it didn't disconnect itself.

So, it happens randomly. I never had this problem with my iBook. Any MBP owners here also have this problem?

I had that problem for the first 3 days with my MBP and a Linksys router. Has not happend since then. I am using hide ssid, WPA, and mac filtering.

Wait a little longer and see. It actually happens quite randomly.

Nothing happens to me. I have a linksys and it works awesome.
