Well, this article will help you with the step by step guide to on how to use your own router with AT&T fiber without spending any extra penny on a new router.

Can we use your router with AT&T fiber?

Yes, you can use your own or a third-party router with AT&T fiber. They provide a residential gateway as you buy their subscription for AT&T U-verse or AT&T fiber. Setting up a third-party router is quite convenient. But, compared to the high-end routers provided by AT&T, which consists of a lot of features, your router might lack some.

Why should you get a third-party router? 

Before we explore further details about setting up your router, let us first understand why you would want a third-party router anyway? Although, there are no arguments, AT&T does have some setbacks when it comes to configuring other routers except their own. AT&T's residential gateway might be troublesome in some respects.

Sometimes, you might face problems while setting up your DNS servers. This is a significant setback as it means either to choose a lower performance and weak security or to learn all the nooks and crooks of hard coding to set it up. Coming to another practical viewpoint, the budget is also a concern while shopping for an internet connection.

Though AT&T provides benefit plans at an affordable range, their routers can be a bit expensive. Moreover, their pricing on routers are not flexible and only offer generic features. On the other hand, you can shop for a third-party router, where you will have a sea of variety to choose from.

Besides, AT&T does not offer any parental control features. This is a setback but also an advantage if you use it wisely. Many third-party routers come with remarkable parental control features and give you absolute control to turn the internet on and off.

If you want to use the third-party router and the AT&T router together, you can use it via Bridge Mode configuration. This mode helps you connect both the routers on a single network without deteriorating the bandwidth's performance. This mode works by disabling the Network Address Translation or NAT feature present on the modem and avoids conflicts between IP addresses by authorizing the router to act as a DHCP server. 

Although there are some constraints to using the bridge mode, it is not possible to use it up to its full potential with an AT&T gateway. Using this passthrough mode also means that your firewall remains disabled, thus making your desktop or laptop susceptible to breaches.


Technically, buying your router seems quite reasonable as you can control the budget and have your own desired features. Although the set-up can seem a bit tiring and there might be some backlash if you decide to use both the routers.

Moreover, using a third-party router also means that AT&T will not provide you with any customer assistance. You can seek help from the router company as well. This was all about how to use your own router with AT&T fiber. I hope that you find this article useful and interesting.
