Like Swae, I too am still having issues here - and this is one of the strangest networking issues I've run into. It's also very repeatable, so at least that makes things easier to test.

The wireless box is 100% reliable. But when I turn on the wired box, in about 30 seconds the wireless loses connection to the router. At first I thought maybe it was electrical noise from the wired box. So I unplugged the wired box from the network and turned it on. Problem went away. So there's some sort of network incompatability that's causing the wired box to bump the wireless box. I've never seen this before. The thing is, it's only that one wireless box that fails. All the other wireless machines work fine.

So I checked DHCP. I set the router to assign a static IP address to each machine now, based on MAC address, to see if maybe it was assigning the same number or something. No change in reliability. (though I do like the tidy aspect of having assigned LAN IP address for each machine now).

I can tell the wireless box to disconnect from my wireless router. And then reconnect. I get great connection again - for about 30 seconds. Then, out. It won't even connect to the wireless router (192.168.1.1), BUT it see's the wired box on Homegroup. That's weird. So I disconnected it from Homegroup. But that didn't help.

Any thoughts on this? It almost smells like a Win 7 bug of some kind.

Edit - took the wired box off of Homegroup, and now it's looking like the wireless is working again. Weird.
