Multi Question | 2gig + XB7 & 2gig XB7 Bypass (looking for the limitations) | Why must we use your gateway for standard ethernet equipment

I am seeking clarification regarding the authentication process for my ONU to my Gateway. Through PCAP, I can see you are implementing EAPOL (802.1x) in some form preventing simple direct connection to 3rd party gateways.

Up until now, I have been able to use your gateway in bypass mode and use it without any issues, as my 1 gig service functioned adequately. However, I recently upgraded to the 2gig service, which unfortunately does not include a gateway with dual 2.5gig Ethernet. While this is understandable for anyone using Xfinity Wifi directly, which I am not. I require more than one 2.5-gig network port for my setup.

My ultimate goal is to connect your 2gig service directly to my existing 2.5-gig wired Ethernet 3rd Party gateway without using any Xfinity gateway. This is because I already have appliances that provide the necessary services.

If possible, could you please explain the technical reasons behind these limitations? Understanding this will help me make an informed decision regarding how best to proceed with my internet setup.

I also would like to know the answer to this as I'm in a similar predicament. My xfinity gateway is not capable of providing my devices the 2gbps speed the service is supposed to provide. My own equipment is capable but I can't connect it directly to the ONT.

talvifox Thank you for reaching out via  our Xfinity Community Forums. and for your very detailed and well-informed question. I understand your frustration with the technical limitations you've encountered, especially after upgrading to our 2 Gbps service to get more speed for your advanced home network.

 

You've correctly identified that our network uses 802.1x authentication, which is a fundamental part of how we provision and secure our services. Our gateways are specifically designed to perform this authentication, ensuring that only certified equipment can connect and receive the correct speed tiers. This is why a third-party gateway cannot directly connect to the network in the same way. The bridge mode you're using is the official, supported method for customers who want to use their own third-party router. We understand that this is not ideal for your setup, as it limits you to a single 2.5 Gbps port, but it is a necessary part of our network's design.

 

At this time, we do not have a way to allow a direct connection with a customer-owned gateway for this service tier. We know this can be a significant limitation, and we're continually evaluating our equipment and policies to better meet the needs of our high-speed customers.

 

We truly appreciate your feedback. It helps us understand what advanced users like you need and helps guide our future product development.

Is there any plan to roll out better Xfinity hardware like the XB10 to these plans? Even if you aren't using your own Router with XB7/8 in bridge mode there is no way for the XB7 or XB8 to provide an Xfinity user the service they are paying for. The wifi does not go 2gbps FD and because there's no LAN ports on either device that go fast enough there is literally no way for the XB7/XB8 to provide service for that network tier. Not to mention both of our networks from Xfinity are being fed 10gbps from the Xfinity ONT so if Xfinity does plan to offer higher speeds they wont be able to due to the hardware limitation.

@user_szc2qr​ I'm fighting this same situation right now. I even had a XB10 in hand and the tech/backend phone techs could not/would not connect it to my network. Every person I speak to on the phone will only respond with the information provided on their screens saying the XB7 "supports 2gig speeds" and won't listen to why it will not work for fiber setups that want a 2.5g port available to use those said speeds. They all offer to upgrade to the XB8 but the port layout is the exact same. No one will send me the XER10 and the techs swear the XB10 will not work for fiber networks. It's insane to pay for speeds you fundamentally cannot use due to the hardware provided and REQUIRED despite the gateway doing zero modem work and is purely a router at this point. I have my own WiFi 7/full 2.5g ethernet router but it cannot receive the speeds I'm paying for through the XB7 ports

They will not provide any device that their system claims isn't "compatible" with your service area, which means they will only provide XB7 and XB8 for EPON services (even though the XER10 "uses the latest WiFi 7 (802.11be) standard and tri-band technology to deliver ultra-fast, multi-gigabit speeds for customers in Fiber-to-the-unit (EPON) residences." according to their own website) ON TOP OF THAT, in researching the XER10, bridge mode is not available so you will be stuck with double NAT or only AP mode for a 3rd party router.

Hello, @user_5ye2ag! Thanks for reaching out about your 2 Gig speed and capabilities of the equipment in your home. The technicians have final say on the equipment that is installed in your location but as of 8/14/25, the XB10 and XER10 are the recommended setup for EPON 2 Gig locations. The equipment has to be professionally installed. Have you had a technician come out in the last few weeks or was it before that?

This is false, I had an Xfinity Rep tell me last week that the EPON 2 Gig is not allowed to get the Xb10. You can look in this users support chat if you are curious. It was funny though because the people on the phone with numerous departments and the people in the store both said it was ok. Not sure whats going on with all of the confusion.

@XfinityRay​ If plugging in an RJ45 is a "professional install" y'all need to go back to the drawing board. 

It is not abnormal for users to have their own network equipment. Your statement is not acceptable behavior.

Moved to 1Gbit and wondered the exact same thing. They over provision at least 20%(which is great) so I'm missing out on 200-300mbit essentially and am also forced to power this extra device just to be a router with a 1gbit port limit. Speed should be limited at the PON and have nothing to do with the gateway... I understand the 9999 other reasons why they would want you to run it. If you connect to another port on the XB7 it will give you a 2nd WAN IP and speed testing between both provides full bandwidth -_- -- I don't care enough to use that as anything more than a test but it's interesting.

I have this same problem. Just got 1 gig service 2 days ago with a XB7.... No reason they should be giving this old modem/routers out for gig plans. We are being bottlenecked because of it.

Verizon installed conduit in my neighborhood not too long ago I think the only solution is just hope another ISP that cares about their customers comes along. Verizon's fiber network lets you use your own equipment, seems like the only answer at this point.

So, It seems far more likely we will be getting an XER10 https://www.xfinity.com/support/articles/broadband-gateways-userguides XB10s will likely be pushed to DOCSIS 4.0 customers only, as we have EPON Fiber.

The local technicians are having meetings about it, and word travels fast. But Xfinity Corporate is playing this very close to their chest.

I don't like this solution, as its being spread that it doesn't support Bridge mode. (feel free to confirm or deny)

Any comments Xfinity?


You can certainly bring this back to your boss'. If you don't allow me and frankly many of us to use our own routing equipment the way it was intended with external IP address access. Rest assured we will find other options. I will not be uprooting my Unifi Network just because your engineers think they are smarter than the average customer or worse, you marketing team is too dense to understand what we want.. Being the first other option doesn't make you the only option in the area.  :)

@talvifox​ they will absolutely not activate a XB10 on fiber/epon, I fought this for weeks. Eventually did get a XER10 installed and yes it absolutely does not support any sort of bridge mode. It's extremely locked down and everything is forced through the phone app (nearly everything on the admin page just says to open the app and have zero access to settings from the page)

@user_5ye2ag​ So no bridge through the 10.0.0.1? Hmm I've been trying to get a XER10 and now im not sure if it's worth the trouble. Though I'd imagine they will have to enable bridge at some point via an update.....

Hello @user_xsx3xt you have an appointment coming up shortly. The tech should be able to help you with your bridge mode needs.

@XfinityDuron Seems the XER10 doesn't support bridge mode from this forum and Reddit users. Seems like a massive oversight and needs to be implemented to allow users to use their own equipment
