Oh my laptop I didnt install anything and it shows me all sorts of
networks by default. Dont know about Wifi radar.

Where does it show you?................

Top right, there is a network icon. If you click on it you can see a
wireless menu and it will show you the networks in the area.

it only shows mine, is this a driver issue perhaps? Maybe a better driver shows
more from the Netgear Usb device?

If it was a driver issue then you would not have any wireless. It is most
likely a setting. You may need to set it for roaming.

The dropdown on Network Manager may not show all networks. You can go to
Show Hidden Wireless Networks at the bottom. I am familiar with Wifi Radar,
but find that network manager meets my needs. You may also want to look into
SW Scanner. It has wardriving features and may be what you are looking for.

Check the KISMET site to see if your wireless adapter is compatible. If so,
download and install kismet and see more than you would ever want to see. You
would have to manually input the network name to connect, but you should be able
to see networks with kismet.
