Saw this over at Slashdot. Apparently, the FBI is making a habit of cracking WEP encrypted wireless networks (WEP is probably the most common form of network encryption for average home users). If I was them, I wouldn't exactly be announcing what I was doing. If you use WEP to encrypt your network move to WPA (assuming your router supports it). Check your documentation if need be. Go buy a new router that supports WPA if your current router does not.
