After a fresh install of Windows on my laptop, I started having ICS problems when I would try to connect my Xbox through my laptop's Ethernet cable.
In my previous installation everything worked fine, but in the recent installs I've done something seems to be wrong. I fresh installed with a different ISO twice to double check, and I can confirm both my wireless card adapter and my Atheros LAN adapter work independently, BUT as soon as I change the ICS properties of either one, the network becomes unidentified. I can't access the internet and it doesn't say the connection is shared. As soon as I turn it off, it goes back to normal.
