Can Xfinity Home Security work with internet wireless gateway in bridge mode?

[justsomeguy3]

I attempted this with tec. He was unable to get it to work. Are any requirements to doing this.? Does it matter which port is used in on the XB6?  Or where the side car is placed in the network ( xb6 to personal router then side car )

Did you call XHome to schedule your tech visit?

Try calling XHome Services 1-877-298-0874

Yes, A scheduled tec came out. Can this be done in bride mode?

My XB6 is in Bridge Mode and my XHome Security works fine.

I like the XB6 because it removed the need for the XHome sidecar modem.

I would also like to do this. I have an ASUS RT-68U that I would like to use because it has a lot of features the xFi modem does not. Guest wifi for starters.

To use bridge mode, is it just a matter of associating Ethernet port 2 to Xfinity Home network and plug the touchscreen into it with an Ethernet cable? I know the touchscreen has to have its own wireless network, but if Ethernet port 2 is associated to the Home network this should do the same thing, right? Or do I need to have a tech come out? I'd really rather not have to do that.

I believe I have the XB6.

Vendor is Technicolor, model is CGM4140COM.

Sorry, I didnt word my question very well. I know how to put the modem in bridge mode; what I'm needing to know is having put it in bridge mode and associating ethernet port 2 to the Xfinity Home network as previously mentioned, will I be able to connect the touchscreen to the modems ethernet port 2 and have it work, or do I need to call out a tech to do some further setup? Or will it work at all? I know the tech needs to put in a code to initially set up the touchscreen on wifi, does this also need to be done if it's connected via ethernet cable?

If you have the XHome Sidecar, depending on which Xfinity Gateway you have will have an issue.

I don't have the XHome sidecar modem because my XB6 has it built-in.  Putting my XB6 in Bridge Mode turns off Eth-2 port.

I have an ethernet cable run from my XB6 to my Den, where I have an 8-port switch for all my streaming devices and my DVD player and my TV.

I have another 8-port switch in my computer room where I have two computers and my Orbi for wifi.

Have you got this resolved? I tried to use Google Nest Rounter/ Points to increase the WiFi coverage.  As soon as I enabled the bridge mode on the gateway, the Home security touch screen  lost connection. Xfinity tech came and couldn't get it to work too. He tried to re-connect the touch pod to gateway but no lock.

mbraces -

That is strange indeed. I can tell you that RobertWy is correct.  If the Touchscreen is properly associated to the Xfinity Wireless Gateway (XB3, XB6, or XB7) and you place it into Bridge Mode, doing this will not impact the private WiFi connectivity to the Touchscreen.

Are there other variables at play here, such as the use of an Xfinity Home Side Car Router (Netgear WNR1000), or are you possibly positioning the Gateway differently at the same time as putting it in to bridge mode (i.e. inside a cabinet that could be introuducting WiFi connectivity issues)?

Here is the official documentation on Bridge Mode and how it affects Xfinity Home, if that's helpful:

Impact on Xfinity Home: Once in full Bridge Mode, customers may connect their personal router to any of the Ethernet ports on the Wireless Gateway; however, if Ethernet port 4 is used for the Xfinity Home (XH) network, it will only work for Xfinity Home service. If the Gateway is not providing Xfinity Home service and no Xfinity Home router is connected, customers will need to connect the Xfinity Home router to any available port on their personal router. If the Gateway is providing Xfinity Home service, then there is no change required in the Xfinity Home configuration. Please note that configuring Ethernet port 4 for Xfinity Home can be done through the Admin Tool (Gateway > Hardware > LAN); by default, port 4 is mapped to a private network, and a customer or technician can map port 4 to the Xfinity Home network.
