The light on the adapter turns red / green by itself. Sometimes while playing. We've only been able to go wireless for 10 minutes, however. When we unplug it sometimes its red, sometimes green. What's happening? It's Microsoft's Xbox live adapter. We use a N type wireless router.
Initially we didn't pay attention to the light and got various error messages... router not showing IP address, etc. Two pc's are successfully wireless with this router.
