ANSWERED: How To Turn Bridge Mode on and off on Xfinity modem

Turn Bridge Mode On and Off on Your Wireless Gateway

Typically, two pieces of equipment are required to connect to the Internet and the WiFi network in your home:
  • modem connects your home to an Internet Service Provider's (e.g., Comcast's) network.
  • router connects your wired and wireless devices to your modem.
The Xfinity Wireless Gateway puts the technology of a modem and router into one piece of equipment, creating the fastest, most reliable in-home WiFi.

We understand, however, that there may be times when you may want to use your own router.

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.

Xfinity XB7 not requiring bridge mode?

Just received a new XB7 modem from Xfinity for my home Internet to replace an older Technicolor XB3.

On the XB3 I had to run it in bridge mode as I have a BOVPN between my home and work networks using the public IP of the T-20 as the BOVPN endpoint. Which worked perfectly fine.

I installed the new XB7, activated it, and much to my surprise the BOVPN tunnel came right up and worked perfectly using the DHCP address the XB7 assigned to my T-20. No need for bridge mode, pass through, port forwarding etc....... on the XB7, or public IP's on the back side of my firebox.

No only that it's much faster.

Out of curiosity I placed the XB7 into bridge mode and the T-20 wasn't able to obtain an IP address from Xfinity. Disabled bridge mode and everything worked fine again.

Is this expected behavior from the XB7 modem or did I finally get lucky for once?

A pleasantly surprised,

It's usually something simple.

Bridge mode does not do what is explained

I had an older arris modem and used it with my night hawk r7000 and it worked great.  I got about 100mbps over wifi.  The built in wifi did not work well for the size of my house so I used my night hawk.  The modem started having problems so xfinity gave me a new modem.  Again the modems wifi did not work well, so I used my night hawk and again it worked, but the speed was much slower (20mbps).  I spoke to xfinity and they said in order for my router to work to it potential I needed to enable the wifi bridge mode to turn off the modem wifi and enable the potential of my wifi.  It made sense so I went into the admin settings and enabled the bridge mode.  This actually stopped all my wifi routers from connecting.  I even tried using my google hub and same thing.  When I disabled the bridge I was able to use it again.  I think there is some confusion with xfinity.  Any idea what is going on and why bridge mode disables my wifi routers from connecting to the internet?


How to Use a Comcast Gateway with an Existing Router

Your Comcast Wireless Gateway has a built-in router, providing a way to connect both your wired, and Wi-Fi devices. Sometimes, you may wish to use your own router instead, and have your Comcast Gateway act simply as a modem.

This is known as as 'Bridging' the Gateway. This guide will walk you through turning on bridge mode for your Comcast Wireless Gateway.

xFi Wireless GatewayxFi Advanced Wireless Gateway
Comcast Wireless Gateway first version.Comcast Wireless Gateway second version.

Before continuing, it's important to understand what exactly bridge mode does.

By default, your Wireless Gateway offers all the functionality of a modem and router in one device. It turns the signal coming in from the cable line into something a computer can understand, provides a way to connect multiple wired devices, a way for Wi-Fi devices to connect, and offers basic firewall capabilities.

When Bridge mode is enabled, the only function that is still active is turning the signal from the cable line into something a computer can understand; the same function a modem does.

In Bridge mode, your Gateway:

  • Will not provide Wi-Fi, this must be taken care of by your own router
  • Will not provide multiple wired ports, only one will be active
  • Will not provide any routing services, only one device may be connected to your Gateway
  • Will not provide any form of security to your devices
  • In effect, it will act as a standard modem
In most cases, you will need to have your own, separate router available to provide services to your multiple Internet-capable devices.
In most cases, un-setting bridge mode will require factory resetting your Wireless Gateway, and possibly contacting your ISP to re-set this setting.

In order to make changes to the Wireless Gateway, you must be connected to it directly, and not to any other router you may have.

Computer connected to Gateway.

Before continuing, make sure your computer has an Ethernet connection to your Wireless Gateway, or you are connected to the Wi-Fi connection provided by your Wireless Gateway.
  1. On your computer, open your preferred web browser.
    Main Desktop Browsers.
  2. In the address bar at the top, type in, and press return or enter.
    Address bar with address entered.
  3. Enter your Wireless Gateway Administration Username and Password, then select Logon.
    If you have not logged in before, or never changed it, the default information is:
    This username and password is case sensitive; in this case, it must be all lower-case letters.
    Admin tool login with Username, Password, and Logon button highlighted.
  4. On the left, select Gateway > At a Glance.

  5. In the center, for Bridge Mode, select Enable.
    Bridge Mode settings highlighted.
  6. A warning message will open, informing you again that the wireless and routing capabilities of your Wireless Gateway are about to be turned off. Select OK.
    Warning about bridge mode with OK highlighted.
  7. Your Wireless Gateway will reboot, to complete Bridge Mode setup.

When your Wireless Gateway is in bridge mode, there are some special considerations you must take into consideration.


All wireless functionality is disabled. You will need to use your own router to connect anything wirelessly.


No routing is performed on traffic coming in. Because of how the Internet works, this means only one device, usually your own router, can be connected to your Wireless Gateway.


No protection in the form of firewall or even simple network separation is performed. Again, this is fine if the device you intend to connect is your own router, it can provide those services for you.

Only One Wired Connection

Only one Ethernet port on the back of your Wireless Gateway is active, Port One. This is where you will need to plug in your own router.

XB1, XB2, and XB3 Comcast Wireless Gateways

Port one is the only active port for Internet service when Gateway is in bridge mode.
Back of XB1 Gateway with Ethernet Port one highlighted.

XB6 Comcast Wireless Gateways

Port one is the only active port for Internet service when Gateway is in bridge mode.
XB6 Gateway with Ethernet port one highlighted.

In some cases, some older Wireless Gateways with outdated firmware installed on them can have problems showing the bridge mode setting.

You will need to reach out to Comcast to set bridge mode for you, or replace your Wireless Gateway with a newer model.

What Is Bridge Mode Xfinity


The modern world is surrounded by countless science inventions and new technological advancements are continuously being made in each and every field, especially in the vast field of telecommunication. One such highly advanced service providers are Comcast Corporation, leading the telecommunication and media world to new peaks of success.

A subsidiary of Comcast Corporations, Comcast Cable Communications (LLC), is responsible for providing television cable, internet facilities, telephone communication, and wireless services to the people of America. In 2010, the firm introduced a business name for Comcast Cable Communications (LLC) and now the corporation is known to its customers under the brand name of “Xfinity”.

Xfinity has become a well-known brand among the telecommunication and network sphere. It has achieved many high positions and has been serving a majority of the customers with its various services. Xfinity is the largest television cable and Internet service providing company in the United States. It is also the biggest pay-tv company of the United States and the third biggest landline service provider of the nation.  Moreover, Xfinity is the second-largest cable television and broadcasting company in the world.

Introduction to Bridging

As the name indicates, bridging means bringing the two different parts together to form an interconnecting intersection point by forming a ‘Bridge’ between them. Network bridging is the phenomenon of creating a bridge between two separate networking segments to form a single aggregated communication network.

A device that serves as a network bridge is usually a computer network modem that can also be wireless depending upon the connecting communication networks. There are three different types in which a network bridge can be formed i.e. Simple Bridging, Multiport Bridging, and Transparent Bridging.

What Is Bridge Mode Xfinity?

What is a Bridge Mode?

A Bridge mode is a system that connects two separate router connections without disturbing the performances of each. It is a set of configurations that invalidate the featured Network Address Translation on the modem and enables the router to work as a DHCP server with no conflict of an IP Address.

To expand the coverage area of your wireless internet services can be done by connecting multiple routers of your home or office facility together. But if you have got two different routers where each of the routers is provided with its own private Wi-Fi network, it is not a piece of cake to connect them. Personal devices may resist mutual connection and have a hard time communicating with one another.

For example, you have a wireless scanner that is provided with a Wi-Fi service of a network other than that of the network which is connected to your computer. Now, if you wish to scan some work documents into your computer in a hurry, your scanner will not be able to scan the required documents to your computer screen until you connect them.

This is because both the computer and the scanner are connected to their separate Wi-Fi networks. By using a bridge mode, this issue can be fixed because bridge mode helps multiple routers connect by sharing one single Wi-Fi network.

What is the need for a Bridge mode?

Usually, whenever two NAT devices are attached in a series combination, it is likely that the device can misbehave. Configuring your modem into the bridge is mode is preferable to avoid any future conflictions. The bridge modem must be formed before connecting to the router. This way the third-party applications will not require a public IP Address for a successful connection.

What does the Xfinity Wireless Gateway do?

The wireless gateway from Comcast Xfinity gives you a device equipped with the technology of a modem as well as a router, creating the most reliable and fastest Wi-Fi network connectivity available in your home for all of the rooms of the house.

By enabling the Bridge Mode, it is not necessary to disable the Wi-Fi Home Hotspot feature. However, at any moment if you wish to use your own router, firstly you will need to validate the Bridge Mode feature of your wireless gateway to switch off its routing feature and only switch ON the modem capabilities

The Xfinity Wireless Gateway creates a secure wireless communication network and helps you to connect all your electronic devices together with a single safe network such as your computer, cell phone, gaming systems, printer, tablets, etc. without causing any issues or conflicts.

Turning Bridge Mode On and Off on your Cable Modem

With a cable internet provider (e.g., Comcast), two pieces of equipment are required to connect to the internet and the WiFi network in your home:

  • A modem connects your home to the Internet Service Provider's (e.g., Comcast's) network
  • A router connects your wired and wireless devices to your modem

The wireless gateway (like Comcast's XFINITY) is a common way cable Internet Service Providers (ISPs) combine a modem and router into one piece of equipment. 

To use your own router (e.g., a Router Limits enabled router) you will have to enable the Bridge Mode feature on the wireless gateway, which turns off its routing capabilities while leaving the modem capabilities on. Then you can connect the Router Limits enabled router to Port 1 on the back of the gateway modem.

Follow this link for instructions on how to enable Bridge Mode on a Comcast modem gateway:

If you are using a cable modem other than Comcast, you should be able to find instructions for it on the internet.

If you are unable to enable Bridge Mode on your modem, or find instructions on how to do it, please contact your ISP and have them assist you.

Xfinity bridge mode no internet issue can give serious troubles! You’ll find many different guides on resolving the issue about the Xfinity Bridge Mode having no internet. But, most of these are generic guides that are done across all routers.

In this guide, we will give you the most detailed steps in resolving the Xfinity Router Bridge Mode no internet problem.

We’ll be talking about what is bridge mode on Xfinity, how it’s different and advantageous – to how you can solve its most common problem, which is showing “no internet.”

Before we dive straight into the topic, how well do you know what Bridge Mode is?

What is Bridge Mode on Xfinity Router?

what is bridge mode xfinity

In technical terms, this functionality is a configuration or a function that allows a router to work as a Dynamic Host Configuration Protocol (DHCP, while disallowing Network Address Translation or NAT on the modem.

For you to understand it better, it’s a feature that would let you link two (2) routers, while guaranteeing zero risks of internet speed loss.

In Xfinity gateways, it’s a feature that would help you divide and slice up a Local Area Network (LAN) into different parts safely.

What are the Advantages of Bridge Mode?

advantages of bridge mode

Many establishments, especially those that are big and humongous, need it to send internet connections to different routers scattered all around.

It is responsible for the spreading of bandwidth without the risk of packet data loss. Here are some of the advantages and benefits of enabling this functionality:

Decrease in Bandwidth Loss

Since a bridge mode is something you use to directly connect to a network, an effective bridge mode can cut unnecessary data between segments; all the while managing the flow of traffic in a given network.

Thus, reducing bandwidth loss, which ultimately makes the sending and receiving of data within your network faster.

Enabling Line Topology

Line Topology sometimes referred to as “Bus Topology,” is a network where the nodes are linked only to a specific cable.

With a bridge mode, bus topology is used; allowing a single device to send pieces of data to all PCs within the same network by sending it to one unit or PC.

This is efficient in sending out bulk data or information without the hassle of sending it one-by-one.

Reduction of Traffic

Since not all devices are going to be connected to a single network, the traffic that a router will get is greatly reduced.

For example, if a router is designed to hold and accommodate 25 PCs, and the PCs connected to that router exceeds 25, there would be problems sprouting out.

However, if there’s bridging, then you can directly link PCs to the original router, and other PCs to another.

These are just among the many general advantages and benefits of WiFi bridging.

Understanding Xfinity Bridge Mode No Internet

xfinity router bridge mode no internet

Akin to other routers in the market, Xfinity routers also possess bridging capabilities. Meaning, you’ll be able to use two (2) or more routers at the same time for linking and connecting.

But, there are instances where users experience a “No Internet” error via the Xfinity bridging function.

No Bridging Facility

A lot of people don’t know that bridging from Xfinity routers, in fact, all other types of routers wouldn’t be possible if the secondary router does not support bridging.

So, what you need to do is to check your secondary router and see if it supports WiFi bridging. You can ask the salespeople from where you bought it from; but more often than not, newer routers would be the only ones capable of having it.

Configuration Issues

Configuring this setting on a Xfinity router, in all honesty, is not an easy thing, especially for beginners.

There are a lot of settings involved that you need to toggle to. There might be a problem with how it’s connected to the secondary router, there might be some provider-related internet problems as of the moment, etc.

If you’re not sure how you can configure your router, contact the manufacturer or the store from where you purchased it.

Additionally, you can also read a couple of guides about configuring and setting the router up.

How Can I Fix the Xfinity Router Bridge Mode No Internet Issue?

how to fix xfinity bridge mode no internet

Getting a no internet error is just one of the most common problems you experience while you have the bridging enabled.

It’s so common that people come up with a lot of different scenarios and situations regarding it. When, in reality, the only solution is to toggle the bridge mode functionality ON and OFF.

You can consider it as power cycling the bridge mode functionality, and here’s the best and the easiest way to do it:

Step 1. Access the Xfinity Router Admin Tool

For you to start with the procedure, the first thing you have to do is to access your Xfinity router’s admin tool.

To access it, open up a web browser and type in to access the admin tool.

NOTE: Your Xfinity router must be connected to your modem directly. You can do so via an Ethernet cable.

Step 2. Enter Your Credentials

You’ll see a login prompt where you’d have to input your Username and your Password. If you haven’t changed it yet, the username would be admin, and the password would be password.

NOTE: The password is case sensitive, so you need to make sure that you’re inputting the correct password.

However, if you’ve modified or changed the password, log-in using the new password you’ve set.

Step 3. Locate “Gateway” From the Side Tab

After you’ve successfully logged in, you will see many options on the left-hand side of the page.

In this regard, since we’re looking to toggle bridge mode, you need to hit on the option that says Gateway.

Under Gateway, click on At a Glance. This is somewhat an overview of your modem or your gateway, it’s where you’ll see the configuration of your gateway.

Enable Bridge Mode

Under the configuration option, you will see the option that says Bridge Mode with buttons beside it saying Enable and Disable.

Step 4. Toggle it and Reinsert Cables

If it’s currently turned on, turn it off for 1 to 2 minutes. While waiting, remove and reinsert the cables that run on your gateway, as well as the secondary router you have.

On the other hand, if it’s turned off, turn it on and repeat the steps above.

It Still Doesn’t Work – Is My Xfinity Router Broken?

Coming up with a conclusion that quickly wouldn’t help. If you were able to toggle this option via the admin tool, and you’re still not getting anything, the next best thing to do is to contact Xfinity’s technical support department and ask for assistance.

Before you say that your Xfinity router is bricked or broken, try asking for assistance first. Tell them that you were able to do the steps we’ve discussed and it’s still not properly functioning.

There might just be some problems with how you’ve set your router up. Alternatively, it could be a problem with the cables connecting your router to your gateway.

Secondary Router Problems

Another possible cause would be problems with your other router, not from Xfinity.

Should this be the case, contact the manufacturer of the other router you have and ask for their help. They should have the answer to the connection problems you’re currently experiencing.

Fixing the Xfinity bridge mode no internet issue is actually a moderate thing to do.

You neither have to be an expert nor to be a network specialist to resolve it. You can simply toggle the WiFi bridging functionality via Xfinity’s admin tool and you’ll be good to go!
