Wan bonding to achieve speeds higher than 940 mbps
So i currently have the gig plan. Received email saying its been increased to 1200mbps. I have a Motorola MB8600 modem that supports wan bonding to achieve higher than gig speeds. There are a few consumer routers from netgear and asus that also support wan bonding. Question is does Comcast support this? If i go ahead and bond the other wan port on my modem and purchase a wan bonding router...will i see the 1200 mbps? Does Comcast have to provision my modem for this to work or is this just not supported at all?

That function is done locally on the hardware / devices. It has nothing to do with the ISP.

The page at https://www.xfinity.com/support/devices/ lists 5 retail devices approved for 1.2 Gbps, but the MB8600 is not among them. The approved devices all appear to have 2.5 Gbps Ethernet ports, the MB8600 does not seem to have one.
It might be possible to get a bit more than 1 Gbps through the modem using a router compatible with its link aggregation, but if Comcast doesn't deliver 1.2 Gbps to the 8600, I don't think it can provide the full benefit of the 1.0 to 1.2 speed upgrade.

So i finally got this working. I was able to bond the ports on the Mb8600. Ran two cables to a netgear rax120 router. Used the wan port and number 1 lan port and bonded those. The rax120 has a multigig port than can be used for lan or wan. ran a cable from the multigig port to my pc that has a 2.5gb nic on the motherboard. Getting roughly 1400 mbps now.

I don’t know if this is applicable, but i have a asus rt ax86u router, it has dual wan support, so I just run 2 1 gig Ethernet cables from my modem to my router, so my router I can select the wan or lan to support 2.5 gig, so I select lan, I can achieve 1350 - 1400 Mbps

Oddly enough I have a mb 8611 but prefer the xfinity supplied Xb7, so I do what I posted about and achieve the fast speeds, the interesting thing is I get those speeds without even using the red 2.5 gig port on the Xb7, anyway I believe if I read right, your modem has hidden Ethernet ports under a removable panel, so anyway the dual wan is done on the asus router, not on my modem/gateway, all I need from the modem is for it to supply me two 1 gig sources, yes I have a usb 2.5 gig Ethernet adapter
