So, every so often my wireless connection seems to get messed up on my laptop. It is fine for a while recognized as a private network and allows all of my sharing to persist. Then, periodically it'll switch from the name of the connection to say "identifying." When that happens, network discovery and all the sharing options are disabled until it recognizes the network again. I found this on the internet and haven't tested it yet since I'm hesitant to start whacking away at the registry just yet: http://support.microsoft.com/kb/928233 Does anyone else have any ideas? By the way, I noticed the problem while streaming video from my laptop to my XBox360. Every so often the connection will drop. I opened the Network and Sharing Center in the control panel and I saw the icon for the network connection change right before the connection dropped.
