Powerful Wi-Fi you can rely on

The AT&T Wi-Fi Gateway is more than just a router that provides internet connectivity.  It combines the functions of both a modem and a router to handle your home internet needs. It is designed to seamlessly support a home full of smart devices and your most demanding Wi-Fi connections.

A router is a device that broadcasts a Wi-Fi signal out to your home. It typically connects to a device called a modem in order to connect to your internet service provider. A Wi-Fi gateway provides the functions of both a modem and a router in a single device.

A Wi-Fi extender may benefit you if you find your home has poor Wi-Fi coverage, including low speeds or dead zones.

If you are an AT&T Internet customer, you can download the AT&T Smart Home Manager app from the Apple App Store or Google Play Store to help you identify weak Wi-Fi spots in your home and determine if extenders could improve your Wi-Fi coverage.

When shopping for Internet equipment, you may find Wi-Fi extenders offered by vendors other than AT&T. If you decide to purchase an extender from a vendor other than AT&T, keep in mind that it will not integrate with the Smart Home Manager app, and AT&T does not guarantee it will be compatible with AT&T equipment. Additionally, AT&T does not support AT&T extenders purchased on the secondary market via sites like eBay or Amazon®.

1. Press and hold the Reset button on the gateway for at least 10 seconds. If you let go before 10 seconds, the gateway will reboot, but it won’t reset.
2. Wait until the gateway restarts and all the status lights are lit.
3. See if the Broadband or Service status lights are solid green. If so, the reset succeeded.

The best way to find your Wi-Fi network name and password will vary somewhat based on which Wi-Fi gateway or modem you are using in your home. You can go to this page to get detailed instructions on how this works on a variety of popular devices.

Your Wi-Fi connection may be affected by other devices that compete for the same wireless frequencies of 2.4 GHz and 5 GHz. Since 2.4 GHz frequency travels further, devices on the 2.4 GHz band are more susceptible to Wi-Fi interference than devices operating on the 5 GHz band.

Wi-Fi extenders can help extend your 5 GHz network so your devices can avoid using the 2.4 GHz network. Read more about Wi-Fi extenders.

Having to go through physical objects can weaken Wi-Fi signals, which means walls can affect Wi-Fi. A common cause of reduced Wi-Fi performance is dense walls and furniture in between routers and wireless devices. In addition to dense walls and objects, conductive materials can block Wi-Fi signals the most, causing Wi-Fi not to work in some buildings.

Some electronic devices may cause Wi-Fi interference even though they aren’t designed to broadcast wirelessly. If you’re using an excessive number of electronic devices, you may experience diminished Wi-Fi performance. In that case, check to see if your other devices are causing the interference.
