Wireless Networks tab missing

[Doug Robar]

I've installed a USB wireless network card, hardware is
running ok per device manager. (Works ok on another
computer).

When I open Network Connections, Wireless network
connection, all I see is the general and advanced tabs.

The 'Wireless Networks' tab is missing.

How do I get it back? I need to input the various
parameters for my access point (SSID, channel) etc.

Thanks,

Doug
