My wireless connection cuts itself occasionally

[Percula]

Two things come to mind...

1) You have a 2.4Ghz cordless phone near by that is stepping on the WiFi signal and it is not close enough to the others to be a problem.

2) You are too close to the AP and are getting overloaded. Try moving the AP 5-10 feet from the PC.

Of the two, #2 is more likely.
