Can You Use Your Router With AT&T? ( A Detailed Guide On How To)

AT&T helps you to use the Internet comfortably without any problems in your home. While this company provides everything you need to get online, most of you are probably considering switching from a different internet provider to AT&T. But, what if you want to repurpose the old router, can you use your old router with AT&T?

It is possible to use your own router with AT&T Internet service. You can also use a third-party router with ATT. When you buy ATT fibre or AT U-verse, the company offers a residential gateway. Therefore, you can easily set it up with your router. However, if your router is not a high-end router that is provided by AT&T, you may not have all your features.

There are a lot of reasons that can influence why you want to use your own router with AT&T. Everyone wants a router that is able to meet all their network demands. You may be looking for a router that is able to give you high speed, tri-bands as well as other features such as parental controls. The AT&Ts router is not able to offer you some of these things that your router has. AT&T only has features that are generic and therefore, might not really meet most of your requirements. 

Configuring Your Own Router With AT&T Fiber

The following a well detailed guide on how you can set up your router with AT&T.

Step 1: Choose a router

The first thing that you need to do before anything else is to choose a router that you will use with AT&T. Here, you also need to look into the kind of features that you want for your router. Most importantly, this router that you choose should be compatible with AT&T for this to work. 

Step 2:  Locate the gateway login information

When you have completely unpacked the router, you can now start setting it up. First, you need to have the login information for your gateway. You need to have a username and a password for the gateway. Once you sign up for the AT&T connection, you are assigned the credentials. This is very important because it is how you can use the gateway settings or even set up a router. 

Step 3: Log in

It is now time to enter your credentials in order to log in. Use a browser on your PC or desktop. In the search bar, type the IP address This will take you to your AT&T settings. 

Step 4: Changing the Settings

Once the IP address is entered and you have been direct to your AT&T settings. You should then find the settings tab. On the settings tab clock LAN>HDCP. You should change the range to Save the new settings. 

Step 5: Plugging In your device

After completing that step, your Internet turns off automatically. This is the time you can connect your router to the AT&T device as well as to the power source. Start by unplugging the cable from your PC, then plug it in again. 

Step 6: Go Back To The Gateway Settings

You need to go back to your gateway settings. Then go on the firewall section. In this section, you should select pinholes, DMZ, and applications. Once completed, you will see all information about your router as well as the device on your computer’s screen. Then select the router you are currently working with.

Select on the option that says allow all applications (DMZ modes). 

Step 7: Configuring your router

You can easily log into the router configuration page. The router will have a new IP address as this will depend on the kind of router that you are using. Make sure to check that there were no errors in the configuration process. The configuration page also shows you the router’s public IP address. If you find your IP address to be 172.16, you should know that the configuration process did not go well. Therefore, you will have to restart the process. 

Step 8: Disabling AT&T’s Router

The final step is to ensure that the AT&T router is disabled. When getting a subscription, AT&T gives you its own router, but having two routers can easily mess up your settings. 

To disable this router, you use the gateway settings. Once in the settings pages click the option that says “settings”. The clock LAN>Wifi. Make sure that the status is disabled. If it is not then disable it. If you are using a dual-band router, you will have to disable the bands. 

Why Should You Get A Third-Party Router? 

Getting a third-party router can be a very convenient way to set up AT&T. This is because the residential gateway can give you problems sometimes. 

When setting up the DNS servers, you may sometimes face a lot of problems. Therefore, you may end up choosing weak security as well as low performance when setting it up. 

Using a third-party router can be cheap. This is because AT&T provides routers that are a little more expensive. The routers also offer few features, when using a third party router, you have a choice to get a router that provides you with so many features that you need. 

AT&T does not have parental control features. However, so many other third party routers come with such a feature and you can easily turn it on and off allowing you to control your Internet. 

Can I use my own router and the AT&T router?

Your own router can also be used together with the AT&T router. This can be done through a Beige mode configuration. With this mode, you can easily connect these two routers on a single network without worrying about the bandwidth performance. 

The Bridge mode configuration will disable the Network address translation (Nat). This is a feature that is on your modem and ensures that there are no conflicts between the IP addresses. It will do this by allowing the router to act as a DHCP server. 

Using bridge mode also comes with its own limitations, for instance, you can only use the routers to their full potential with the AT&T gateway feature. Using bridge mode will also disable your firewall putting your computer at a risk. 

There are so many ways in which you can configure the setup. This will be determined by the kind of AT&T fibre router that you are using. There is a Motorola NVG 510, Motorola NVG 589 and a 2 wire/pace router. You can determine your device by connecting the router to your PC via an Ethernet cable and following all the instructions that come after that. 

The Motorola NVG 510 and 589 supports three kinds of configuration. There is a DHCPS dynamic, DHCPS fixed and manual configuration.


  1. Enter the IP address in your browser
  2. Once in the settings, clock the firewall option. Then select the IP passthrough option that is found under the firewall tab. 
  3. Enter the device’s access code if prompted
  4. Go to allocation mode and choose the passthrough option
  5. On that option choose HDCPs then save the settings. 
  6. Restart the device


This is suitable if you want to connect to more than one router. The option will assign a specified MAC address and make it operate like a DHCP server. 

Follow all the steps outlined when setting it to HDCPs dynamic. However, in step number 5, you should now choose the HDCPs fixed option instead. 


This involves configuring the router manually. You will need to have the subnet mask, WAN IP address and the default gateway. You can ask for assistance from AT&T. Follow the same steps. However, when on step number 5 choose the manual option. Then save the settings and restart the gateway, after that you can manually configure your router. You will use the subnet mask, WAN IP address, subnet mask and default gateway. 

For 2Wire/Pace Gateways 

For a 2wire/pace gateway, you use the following instructions. DMZplus mode is the name given to the passthrough mode in these routers. 

You need to make sure that your device has been connected to your AT&T fibre gateway. It should also be configured so that it can be assigned an IP address through HDCP. 

  • Start by entering the same IP address in your browsers search bar:
  • Once you are on the page click settings, then go to the firewall.
  • Select the applications, pinhole and DMZ options. 
  • Choose the other device or the IP address. Then click allow all applications (DMZ plus mode) button. Save the settings.
