Is there a chance you have 2 routers in your network?
If you don't know you whole network, click "See full map" in "Control Panel"/"Network and Sharing Center".

Are all your devices using DHCP? or have the allocation refreshed recently? Sounds like you have some stale setup info (especially if you have factory reset the firmware).
