I've had the same issue. Marco's (Nellemar) direction resolved it for me. Thanks, Marco !
I have Ver 1.08 Firmware, but did not change that.
I had reset the camera in trying to solve the problem. I could not get past the "Set your Camera's Password" screen when trying to reconfigure with the Setup Wizrd program (CD).
I plugged camera into my router. I accessed it directly. Here's where it gets to be trial and error.
I originally set my camera up with an assigned IP and Port Number. After the reset, the camera used the IP (assigned by router), but defaulted to Port 80 rather than my assigned Port. So my effort to get to the setup was failing because I was using the Port number in the address (192.168.1.100:252). Port 80 as default only needs the IP address (192.168.1.100).
Note: you may need to try the camera's default IP address assignment of 192.168.0.20
Login ID: Admin
PW: (blank) <- the default is a blank field for the password.
(If you hve not reset the camera, try your old pw)
The reset defaulted defaulted the camera to 'wireless disabled.' Once in the setup program, that needed to be changed back to 'enabled.'
Then you must address any changes to access your router, such as security and password.
Good Luck!
