First check your port forwarding settings, see if there's any conflicting ports or IP's in there. Also, try opening SADP (the software...if you don't have it you can download it from www.nellyssecurity.com). It should detect the cameras and you can change the IP there.Ok, I disabled UPnP on the router and now the cameras say 'Offline (user password error).' Is there a way to reset the cameras and re-activate them through the web interface and plugged into the POE ports?
But I know the password, as I changed all my cameras to the same password that I was required to change (any of the newer cameras).If you turn off uPnP do it from the camera (unless you want to turn it off at the router as well).
User password error aye.. hmmm.
