One device connects but others don't

 I am able to access the internet from one computer, but my router and another computer won’t connect to the internet.

Here’s the history:

  • I lost internet. My modem appeared to successfully reconnect, but my router did not re-establish a connection.
  • I rebooted both my modem (Motorola MB8600) and router (Google Nest Wifi) a number of times.
  • It appeared my modem connected, but when rebooting my router it said it could not access the internet. It appears like it has some level of connectivity, but no IP address.
  • I disconnected the router from the modem, and connected my home computer.
  • I was able to access the internet when my home computer was connected directly to the modem. Using the same cable.
  • I disconnected my home computer from the modem, and connected my laptop directly to the modem.
  • I was NOT able to access the internet when my laptop was connected directly to the modem. Using the same cable.
  • I bought a new modem (Arris S33). Contacted Xfinity to connect it to the Comcast network.   It appeared to be successful from their aspect.
  • I am having the same issues with the new modem – can’t access the internet from my router or laptop, but my home computer can access the internet.

Are you power cycling / re-booting the modem(s) each and every single time that you change the device that is being directly connected to it in order for that device to be able to get an internet connection ?
