Home Internet Services & AT&T Wi-Fi Gateway | AT&T Internet

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®.

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.
