What is a Wi-Fi extender? 

Your home wireless internet works by broadcasting a Wi-Fi signal from the gateway to your connected devices. Wi-Fi signal strength degrades over a large area or when the signal attempts to pass through different mediums. For example, a brick wall will reduce your Wi-Fi coverage more than drywall. Longer distance from the gateway will also reduce Wi-Fi connectivity and can cause speed issues.

Wi-Fi extenders are devices that may help solve this problem. They take the signal from your Wi-Fi gateway and reduce signal weak spots and dead zones while seamlessly creating a single network that covers the entire home. Some Wi-Fi extenders can extend the signal up to 1,000 sq. ft. This means you can take a device and move throughout your home while staying connected the whole time. 

If you are an AT&T Internet customer, you may be eligible to get AT&T Extended Wi-Fi coverage service for an additional fee, which includes a new smart Wi-Fi extender (or more than one if you qualify1), a free extender replacement if it’s defective (as long as you have the service) and tools via the Smart Home Manager app to help you get the most out of your extended Wi-Fi coverage.

How do I know if I need a Wi-Fi extender?

A Wi-Fi extender may benefit you if you find your home has poor Wi-Fi coverage, including low speeds or dead zones. Dead zones are areas where the Wi-Fi connection is bad or even non-existent. 

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®.
