My Sidebar wireless gadget suddenly stopped working. It was fine last night but wasn't working this morning. It shows that I am not receiving a signal from my router (but I'm submitting this post which means I AM online). I rebooted, but no change. I thought to update the driver for my network adapter (Atheros AR5006EG) but I already have the latest driver. I uninstalled the updates that were automatically installed overnight, no change. I found a wireless hotfix (KB932063) online but when I downloaded it I got the message that it doesn't apply to my system (Vista Ultimate). Any suggestions on what I need to do? Thanks...
