why not plug the IP camera into the same modem the PC is connected to?
that's the setup now. the IP cam is plugged into the router with ethernet.
the computer is plugged into the router with ethernet.
the computer has a local ip in the 192.x.x.x range
the camera is supposed to have a factory default ip in the 192.x.x.x range
the router itself has a local ip in the 10.x.x.x range
so the computer should see the camera.
and the router should know there's an ethernet device attached.
but it's not working like that.
there's no reset button on the camera.
