I have the same camera and the exact same firmware. I can confirm your issue is real. The camera does not show any wireless networks when you press the SCAN button.
The only "fix" that worked for me was to manually enter my wireless network info, rather than pick it from the (none existent) list. Put this information in, save the settings and then shutdown the camera and remove the network cable. Once you plug the power back in, the camera should automajically join your wifi (provided you gave it the correct info).
It will have a NEW ip address, as the wireless transmitter has a different MAC address. So either get on our routers configuration page and look for the new device, or try the SearchIPCam.exe app again. I've had mixed results with the SearchIPCam.exe app... but you might be ok.
Once you discover it's new IP, you should be able to configure it, just like before.
