Menu->Settings->Protection->Wifi Inspector.
I see the two Scan and Rescan options, 'Visited Networks,' and 'New Device Notification' but there is no 'Network Scan' button.
Also, the 'Local Area Connection' slider in Wifi Inspector has a red bar through it while it showed 'Public Network' yesterday-The 'Windows Firewall' setting (Win 7 Control Panel) shows a connection with a green check-mark.
