Can Motorola MB8600 Modem be used with xfinity? Connect issue.

Hi,

I got a Motorola MB8600 cable modem to use on xfinity and it is unable to get fully connected to the network. I tried the self install and had a tech come out.  The tech said it could not get or complete the "handshake" with the network. It completed the initial setup, and had all the channels connected and working but would not allow an internet connection.

Anyone else have any issues with the MB8600 modem?

Is anyone else currently using a MB8600 modem?

The Motorola MB8600 modem should be compatible with Xfinity service. It is a DOCSIS 3.1 modem, which means it is capable of supporting internet speeds of up to 1 Gbps. It is important to note that in order to take full advantage of the Motorola MB8600's capabilities, you will need to have an Xfinity internet plan that offers speeds of at least 1 Gbps.

Actually, the MB8600 is only approved up to 949Mbps.

@HelpfulGuy.X 

What you've described *might* be a router DHCP issue.

Is your router complaining about something like 'your ISP's DHCP is not functioning'?

I just had the same issue. The tech couldn’t get the modem to sync and couldn’t send any commands. Did you ever solve this issue?
