Why is the router and modem active on my gateway?
Will this not interfere with my cable modem bandwidth?
Can this be disabled if I call in?
Stuff like the Guide downloads, channel authorizations, SOD items, basically all communications the Gateway needs
No, it won't interfere.
No, it can not be disabled.
So why then is the Wan function enabled on the gateway?
It is being assigned 2 Ip address's. I don't see how this won't interfere with my internet.
The gateway and my modem run off the same cable via splitter.
If you are looking for a more technical explanation, I'll tag our Gateway expert mark_vse here.
There should be a MoCA filter on your splitter preventing the Gateway MoCA network from interfering with your internet or other set top boxes.
The modem that is enabled is not for internet access, but for something that is called DSG "Docsis Set-Top Gateway", this technology allows set-top boxes in your home to communicate with our servers in a much faster, more efficient way. Benefits include faster loading of Guide information, and VOD libraries.
Here is a more technical link on DSG: http://www.cisco.com/application/pdf/en/us/guest/products/ps2211/c1167/ccmigration_09186a00802097cb.pdf
Rest assured, this was all designed to co-exist with your existing devices and not cause interference.

I've got two DPC3825 modems, a phone modem, and my Gateway (connected to another splitter) off of a 4-way coming in, there is no interference with each other
in this this case there is no interference. If you are talking about bandwidth, the contracts on the modems are provisioned for different speeds, and are separate flows. Your inet speeds would not be affected by the gateway. Also, MoCa runs over 1 ghz for the internal network in your home, where as internet runs in frequencies below 1 ghz. They don't cross in this case so again there is no interference.
