I recently purchased a G36 with the intention of eliminating Comcast’s rental XB8 modem at $15 per month. Comcast recommended the G36 as a DOCSIS 3.1 cable compatible modem with download speeds up to 4 Gbps. I have 2 Gbps service from Comcast. I did the install of the G36 and I’m only getting 1.2 Gbps maximum wired out of this modem despite Comcast showing 2 Gbps coming out of their coax cable.
I spoke to Arris Tech Support who have been very helpful and they told me my modem was not commissioned correctly by Comcast.
Comcast field tech is trying to tell me that my Surfboard G36 is correctly commissioned for 2 Gbps.
How can I prove to Comcast that the G36 hasn’t been commissioned correctly?
