Activate on Xfinity Internet with CM1150V
I’m tired of paying $14 per month for rental of my cable modem and router. I have the AX12 in access point mode and is connected via Ethernet to the XFi gateway. I tried installing the CM1150V, activa...
The XFi gateway has too much depth to fit into my electrical panel in the basement, the saving grace of the CM1150V. XFi gateway is D3.1, the cable modem/router I had from Comcast before was 4 port and all 4 ports worked,-----Thats because it was a combo device. Meaning it had a modem and a router integrated. The CM1150V doesn't have an integrated router. but was only D3.0. My internet speed is 600Mbs download so I need a D3.1 modem.
If only 1 port of the CM1150V works, what's the point of having 4 ports? ---Whole purpose is for business lines that are allowed multiple public IP address, the rare ISP that allows consumer lines to have more than 1 public ip address (rare), or for port aggregation on ports 1-2. i wouldn't recommend port aggregation currently as its been a bit flaky. Most consumer's aren't going to need the CM1150v unless they have gigabit and need voice. Same as most consumer don't need the 4x ports on the CM1200. We run into this a lot
So again, unless you're using port aggregation, only port 1 is useful for most people.
so go:
CM1150V--------> AX12 (port 1)------->Devices and switch
don't use the other 3 ports on the CM1150V unless you plan on using wan port aggregation.
plemans - that worked, I changed to router mode and worked with the XFi Gateway.
Step 2 - I had to call Comcast to get the CM1150V activated so they could see it.
However, only devices that can connect to the internet are the devices are connected to the CM1150V. Wireless devices can't connect to the internet, they did with the XFi gateway. Nor can my latop that is connected to an ethernet port on Nighthawk AX12 connect to the internet.
The ethernet cable connected to port 1 on the CM1150V is connected to Internet port on Nighthawk.
What am I missing to get this to work? Frustrating....

Are you using both the Xfi gateway and the AX12?
How exactly do you have it setup? I'll lay out an example for clarity that *should* have everything working
CM1150v------>Xfi gateway (in router mode)------->AX12 (in AP mode)
CM1150v------>AX12 (in router mode)------->Xfi gateway (in AP mode).
Or if you're only using 1 device
CM1150v------>AX12 (router mode)
CM1150v------>Xfi device
any time you switch whats connected to the CM1150v, make sure to reboot it and the device connecting to it. It needs to reboot to reassign the public ip address.
I've never used the xfi gateway so I'm unsure of its modes/functions.
I do know the CM1150v has multiple ports but with xfinity, basically only port 1 works. Make sure you don't use the other ports unless you're using link aggregation. And that still only works for 1 device.
Here's the setup I had before and everything was working.
XFi gateway -----> port 1 - AX12 (router mode), port 2 - 8-port gigabit ethernet witch that connected devices to the rest of house
Wireless devices would connect to the SSID on the AX12.
After activating CM1150V with Comcast
CM1150V -----> port 1 - AX12 (router mode), port 2 - office computer, port 3 - apple TV, port 4 - 8-port gigabit ethernet witch that connected devices to the rest of house
AX12 shows not connected to the internet; Apple TV not connected to the internet, computer isn't working. May have mis-labeled the ethernet cables in the basement.
The XFi gateway has too much depth to fit into my electrical panel in the basement, the saving grace of the CM1150V. XFi gateway is D3.1, the cable modem/router I had from Comcast before was 4 port and all 4 ports worked, but was only D3.0. My internet speed is 600Mbs download so I need a D3.1 modem.
If only 1 port of the CM1150V works, what's the point of having 4 ports?

Thanks, sounds like the CM1150V won't meet my needs. Problem is all my ethernet cables are home-runned to the basement and where I have the CM1150V. The AX`12 is located on the office of the 1st floor of the house.
