I have an 8 port switch plugged into one of the router ports and it works fine on the Arris but none of the devices will get an IP address or work through the switch after I plugged in the RAX40.

 

Does stuff work if you plug into the RAX40 rather than the switch?

 

When you set this lot up, did you take it through the correct startup procedure.

 

You can't just unplug one router from a modem and replace it with another one.

 

Be sure to restart your network in this sequence:

  • Turn off and unplug modem.
  • Turn off router and computers.
  • Plug in and turn on modem. Wait 2 minutes for it to connect.
  • Turn on the router and wait 2 minutes for it connect.
  • Turn on computers and rest of network.

 

What is this dedicated DOCSIS 3.1 modem?
