XB7 in Bridge Mode?

Hi @user_6d2493! Thanks for joining us here in the forums. We recently upgraded several of our speed tiers across our national footprint. The XB unfortunately only had a Maximum Data Throughput up to 1 Gbps while the XB7 can accommodate a Maximum Data Throughput up to 2.5 Gbps, which was the reason for the updated equipment. 

You can still enable bridge modem, I've included information below.

When Bridge Mode is enabled, you will not be able to use Xfinity xFi and xFi Pods (Learn the advantages of xFi). If you are a customer with xFi Advanced Security, you will not be able to access this feature if you choose to enable Bridge Mode on your Gateway. (Learn more about xFi Advanced Security.)

In addition, if you have already activated xFi Pods, you will not be able to enable Bridge Mode. Learn more about network settings required with xFi Pods.

Enabling Bridge Mode does not disable the Xfinity WiFi Home Hotspot feature (available on some Gateways). Learn more about turning your Xfinity WiFi Home Hotspot on or off.

Toggle Bridge Mode On/Off

1. Using a device connected to your home network, open a web browser and go to the Admin Tool at https://comca.st/3p5X2LB. If you are disabling bridge mode, this device must be connected to your Gateway with an Ethernet cable.
2. Enter the default username and password:
   • Username: admin
   • Password: password (case sensitive)
   • Note: If you previously changed your Admin Tool password, use the new password to log in.
     
     
     
3. From the left-hand column, select Gateway > At a Glance.
4. Next to Bridge Mode, click Enable.
   
   
   
5. A message appears stating "WARNING: Enabling Bridge Mode will disable Router functionality of Gateway and turn off the private Wi-Fi network. Are you sure you want to continue?" Click OK to confirm.
   
   Note: Your Wireless Gateway may restart.
   
   
   
6. You can now use your own router in place of the Wireless Gateway's router capabilities. Click Logout at the top right. Connect your personal router to any of the Ethernet ports on the Xfinity Wireless Gateway.
7. If you would like to use your Gateway's router capabilities in the future, log into the Admin Tool and navigate to Gateway > At a Glance. Set the Bridge Mode field to Disable.

I also did the same foolish thing of upgrading from xb6 to xb7. Xb6 was working fine in bridge mode with my tp link archer ax6000 router, but speed dropped drastically when using bridge mode in xb7, sometimes even unusable as the connection the internet was dropped from time to time. Even connecting to xb7 via Ethernet at port 1 did not work or was super slow when it’s in bridge mode. I spent hours on the phone with tech support still no luck. A technician is coming out tomorrow to look at it. 

I am a home integration professional and I have bricked 2 of the XB7 gateways in the last 2 week.  Both gateways were put into Bridge mode and would not connect to the router either time.  The first one was a Apple Airport Extreme and other was Araknis AN-310 router.  After replacing both XB7s I was able to set a static IP address for the router inside the gateway and then enable DMZ mode for the IP address of the router.  It seems to be a good work around. 

Unfortunately It is a huge pain to figure this out on the fly and to have to leave the job for a replacement gateway.

We use Bridge mode for all of our clients.  So if the XB7 no longer supports Bridge mode please remove the option,  

because It is literally the very first option on the home page and apparently no long works.
