CM1000
When I plug the ethernet cord from the CM1000 to the wireless router, internet works fine. But sometimes we shut off the wifi (wireless router) in the house, so I just want to plug directly into the...
Its nothing nefarious.
The CM1000 is a modem only device.
And comcast only assigns 1 public ip address to a modem.
the router is what takes that public ip address and assigns private ip addresses to devices on your network.
When you disconnect the router from the cm1000, you'd need to power the modem off, give it 2 minutes, and then plug a pc/laptop into it and boot it up. That allows that public ip address to get reassigned from the router to the device you connect ot it. Only 1 device would be able to connect because you'll have 1 public ip address.
Most routers have the capability of just turning the wifi off versus disconnecting the router entirely.
What router do you have?
