Aspire One 722 Kills Wireless Network?

[rutilcaper]

I'm having an issue with my new Aspire One 722. I'll be using it fine for a while, sometimes an hour, sometimes a few hours, but eventually the wireless signal will go out. Whatever this netbook is doing, it's killing wireless for everything connected to my router (A D-Link 665). The router still thinks it's broadcasting, but nothing can connect until I either reboot it or reconfigure the wireless settings.

This is definitely a problem with the netbook, it's never happened when the netbook isn't on.

I've tried:
Setting WPA or WPA2 instead of autoassigning on the router
Turning off uPnP (we have two Xboxes in the house and use it to play online multiplayer)
Reinstalling older/newer wireless drivers on the netbook.

Nothing has helped! Googling it hasn't provided any answers, but maybe I'm not searching for the right strings.

Does anyone have any idea what this migh tbe?

What's the wireless card on the netbook?

Does your router have a log? See what it says when the disconnects occur.
