How to Put Your ISP Gateway Into Bridge Mode (Step-by-Step for Every Major ISP)
Key Takeaways:
  • Bridge mode disables the router function inside your ISP gateway so you can use your own router without double NAT problems, which cause slow speeds, failed port forwarding, and device connectivity issues.
  • Most major ISPs — including Xfinity, AT&T, Spectrum, Verizon Fios, CenturyLink, and Cox — allow you to enable bridge mode through the gateway's admin panel or your online account, though the exact steps vary by provider.
  • Before enabling bridge mode, write down your current Wi-Fi name, password, and any custom settings, because bridge mode will turn off the gateway's Wi-Fi and routing features entirely.

What Is Bridge Mode and Why Would You Use It?

If your internet service provider gave you a combination modem/router (often called a gateway), it handles two jobs at once: it connects to your ISP's network and it routes traffic to your devices. That is fine if you do not have your own router. But if you want to use a separate router — for better Wi-Fi range, more features, or stronger performance — you run into a problem called double NAT.

Double NAT means two devices on your network are both trying to assign IP addresses and manage traffic. This causes issues like slower speeds, problems with online gaming, video calls that drop, VPN connections that fail, and port forwarding that does not work.

Bridge mode solves this by turning off the routing functions inside your ISP gateway. The gateway still connects to the internet (it still works as a modem), but it passes the connection directly to your own router and lets your router handle everything else.

Before You Start: What You Need

Gather the following before you begin:

  • Your own router, connected and ready to take over
  • An Ethernet cable to connect the gateway to your router
  • Your gateway's admin login credentials (usually printed on a sticker on the device)
  • Your ISP account login (for providers that require online account changes)
  • A written record of your current Wi-Fi network name, password, and any custom DNS or port forwarding settings

Important: Once you enable bridge mode, the gateway's built-in Wi-Fi will turn off. Any devices connected directly to the gateway's Wi-Fi will lose their connection. Make sure your own router is set up and broadcasting a Wi-Fi network before you switch.

How to Enable Bridge Mode on Xfinity (Comcast) Gateways

Xfinity is one of the most common ISPs that provides combination gateways. Here is how to put an Xfinity gateway into bridge mode:

  1. Open a web browser on a computer connected to the gateway and go to 10.0.0.1.
  2. Log in with the default credentials. The username is usually admin and the password is usually password (unless you changed them).
  3. Navigate to Gateway then At a Glance.
  4. Find the Bridge Mode option and set it to Enable.
  5. Confirm the change when prompted. The gateway will restart.
  6. After the restart, connect an Ethernet cable from the gateway's LAN port to your router's WAN port.

If you cannot find the bridge mode option in the admin panel, you may need to log into your Xfinity account at xfinity.com, go to Devices, select your gateway, and enable bridge mode from there.

How to Enable Bridge Mode on AT&T Gateways (BGW210, BGW320)

AT&T fiber gateways do not offer a traditional bridge mode. Instead, AT&T uses a feature called IP Passthrough, which accomplishes the same thing. Here is how to set it up:

  1. Connect a computer to the AT&T gateway with an Ethernet cable or Wi-Fi.
  2. Open a web browser and go to 192.168.1.254.
  3. Log in using the access code printed on the side or bottom of your gateway.
  4. Go to Firewall then IP Passthrough.
  5. Set the Allocation Mode to Passthrough.
  6. Set the Passthrough Mode to DHCPS-fixed.
  7. In the Passthrough Fixed MAC Address field, select your router's MAC address from the dropdown list. Your router must already be connected to the gateway for it to appear.
  8. Click Save.

After saving, the AT&T gateway will pass its public IP address directly to your router. Note that the AT&T gateway's Wi-Fi may still remain active. You can disable it separately under the Home Network then Wi-Fi section to avoid interference.

How to Enable Bridge Mode on Spectrum Gateways

Spectrum has been rolling out combination gateways to some customers. If you have one, follow these steps:

  1. Open a browser and go to 192.168.1.1 (or the address listed on your gateway).
  2. Log in with the admin credentials on the device label.
  3. Look for a Bridge Mode or Router Mode toggle in the advanced settings.
  4. Switch it to Bridge Mode and save.
  5. The gateway will restart. Connect your router to the gateway's Ethernet port after it comes back online.

If your Spectrum gateway does not have a bridge mode option in the admin panel, call Spectrum support at 1-833-267-6094 and ask them to put the device into bridge mode on their end. Some Spectrum gateways can only be switched remotely.

Alternatively, if Spectrum allows it in your area, you can return the gateway entirely and use your own modem and router. This also eliminates the monthly equipment rental fee.

How to Enable Bridge Mode on Verizon Fios Gateways

Verizon Fios gateways (such as the G3100 or CR1000A) do not have a standard bridge mode toggle. However, you can effectively bypass the gateway's router by setting up your own router behind it and disabling the gateway's Wi-Fi. Here is how:

  1. Connect a computer to the Fios gateway and open a browser to 192.168.1.1 (or use the My Fios app).
  2. Log in with the admin password printed on the gateway.
  3. Go to Wi-Fi Settings and turn off all Wi-Fi radios (2.4 GHz, 5 GHz, and 6 GHz if applicable).
  4. Connect an Ethernet cable from a LAN port on the Fios gateway to the WAN port on your router.
  5. On your own router, set the WAN connection type to DHCP (automatic).

This setup means the Fios gateway still handles routing, but your own router takes over Wi-Fi and local network management. If you have Fios internet delivered via Ethernet (not coax), you may be able to connect your own router directly to the ONT and skip the Fios gateway entirely. Check with Verizon to confirm your setup supports this.

How to Enable Bridge Mode on CenturyLink (Quantum Gateway)

CenturyLink (now Brightspeed or Lumen in some areas) provides DSL and fiber gateways that typically support a transparent bridging option:

  1. Open a browser and navigate to 192.168.0.1.
  2. Log in with your admin credentials (check the gateway label if you have not changed them).
  3. Go to Advanced Setup then WAN Settings.
  4. Find the option for Transparent Bridging and enable it.
  5. Save and reboot the gateway.
  6. Connect your router to the gateway via Ethernet.

For CenturyLink fiber customers with newer equipment, the process may differ. If you do not see a bridging option, contact CenturyLink support and ask them to switch your gateway to bridge mode.

How to Enable Bridge Mode on Cox Gateways (Panoramic Wi-Fi)

Cox's Panoramic Wi-Fi gateways can be switched to bridge mode, but the process usually requires contacting Cox directly:

  1. Log into your Cox account at cox.com or open the Cox app.
  2. Go to My Services then Internet then Manage My Equipment.
  3. Look for an option to enable bridge mode. If available, toggle it on and save.
  4. If the option is not available online, call Cox support at 1-800-234-3993 and ask them to put your Panoramic gateway into bridge mode.
  5. After the change takes effect, connect your own router to the gateway's Ethernet port.

Be aware that enabling bridge mode on a Cox gateway will disable the Cox Panoramic Wi-Fi app features. You will manage your network entirely through your own router going forward.

How to Verify Bridge Mode Is Working

After you enable bridge mode and connect your router, check the following to make sure everything is working correctly:

  1. Check your router's WAN IP address. Log into your router's admin panel and look at the WAN or internet status page. You should see a public IP address (not a private address like 192.168.x.x or 10.0.x.x). If you see a public IP, bridge mode is working.
  2. Test your internet connection. Open a browser on any device connected to your router and visit a website. If pages load normally, you are all set.
  3. Run a double NAT test. Go to a site like whatismyip.com and note the IP address shown. Then log into your router and compare the WAN IP to the one shown on the website. If they match, there is no double NAT.

Troubleshooting Common Bridge Mode Problems

No Internet After Enabling Bridge Mode

Power cycle everything in order. Turn off the gateway and your router. Turn the gateway on first and wait two full minutes for it to reconnect to your ISP. Then turn on your router. This gives the gateway time to establish a connection before your router tries to pull an IP address.

Gateway Keeps Reverting Out of Bridge Mode

Some ISP gateways reset to default settings after a firmware update pushed by your ISP. If this happens repeatedly, contact your ISP and ask them to lock the setting on their end. With some providers, bridge mode can only be permanently set through their system.

Devices Cannot Connect or Get IP Addresses

Make sure your router's DHCP server is enabled. When bridge mode is on, the gateway stops assigning IP addresses. Your router needs to take over that job. Check your router's LAN settings and confirm DHCP is turned on.

Wi-Fi Still Broadcasting From the Gateway

On some gateways (especially AT&T), enabling bridge mode or IP Passthrough does not automatically turn off Wi-Fi. Log back into the gateway's admin panel and manually disable all Wi-Fi radios to prevent interference with your own router's signal.

FAQ

What does bridge mode do on a modem router combo?

Bridge mode disables the routing, firewall, and Wi-Fi functions inside your ISP's modem/router combo (gateway). It turns the device into a simple modem that only handles the connection to your ISP. This lets your own separate router manage your home network without creating a double NAT conflict.

Will I lose internet if I enable bridge mode?

You will temporarily lose internet during the switch, usually for one to three minutes while the gateway restarts. If you already have your own router connected and ready, your internet should come back quickly once the gateway finishes rebooting. Devices connected to the gateway's built-in Wi-Fi will lose their connection permanently until they are moved to your router's network.

Does bridge mode improve internet speed?

Bridge mode does not increase the speed of your internet plan. However, it can improve real-world performance by eliminating double NAT, which causes latency, connection drops, and problems with gaming, video calls, and VPNs. If you are using a higher-quality router than the one built into your gateway, you may also see better Wi-Fi coverage and faster local network speeds.

Can I use bridge mode with any router?

Yes. Any standalone router will work once the gateway is in bridge mode. You simply connect an Ethernet cable from the gateway to the WAN (internet) port on your router. The router should be set to obtain its IP address automatically via DHCP, which is the default setting on most routers.

How do I take my gateway out of bridge mode?

Log back into the gateway's admin panel (usually at 192.168.0.1 or 10.0.0.1) and switch bridge mode off, or set the router mode back to its default. You may need to connect your computer directly to the gateway with an Ethernet cable to access the admin page, since bridge mode disables the gateway's Wi-Fi. If you cannot access the admin panel, a factory reset (usually a small button on the back held for 10 to 15 seconds) will restore the gateway to its original settings.

Is bridge mode the same as access point mode?

No. Bridge mode is used on a modem/router combo to disable the router functions so a separate router can take over. Access point mode is used on a standalone router to disable its routing functions so it can extend an existing network's Wi-Fi. They serve opposite purposes: bridge mode goes on the device closest to the ISP, while access point mode goes on additional routers used to expand coverage.

Does bridge mode disable the firewall on my ISP gateway?

Yes. When you enable bridge mode, the gateway's built-in firewall is turned off because the routing functions are disabled. Your own router's firewall takes over. Make sure your router has its firewall enabled (most do by default) so your network remains protected.
