No one appreciates a dead slow internet connection. Living in a dead Wi-Fi zone in today’s time is nothing less than a nightmare. Wi-Fi technology is not too complicated for the tech-savvy layman. But, many of us fail to understand how Wi-Fi networks function. Rather than identifying the cause of a weak Wi-Fi signal and the slow internet speed, we look for quick solutions. However, more often than not the resolution to such issues is very much possible without seeking a “better internet connection” or for that matter a “better wireless router”.

So, before you rush to quit on your ISP or hurry to buy a new router, it’s important to understand two things: No matter how good your internet service is, it cannot guarantee a strong in-home Wi-Fi network. And, irrespective of how high end your wireless router is, it may not be able to push the Wi-Fi signal to the dead zones in your house. Meaning, neither of the short-cuts, which you are likely to consider taking in frustration, can solve the underlying problem.

It is understandable that once you’ve settled with a reliable internet service provider like AT&T, you’d want to make sure you can enjoy a seamless online experience in all corners of the house. But, while the internet connection and the high-end gateway device provided by AT&T may offer the desired speed and signal strength for all your devices to connect, it is possible Wi-Fi coverage is not evenly spread out around your house. And, there may be nooks and crannies where you are not able to load even a 1.2MB web page.

Why? Because the signal is dead-weak in these parts of your house—we call them “dead zones” for the same reason. And, more often than not it is the size and the layout of a living space that is the culprit behind this.

Using compatible Wi-Fi signal boosters with your AT&T wireless gateway device is the first thing you must therefore consider.

What is a Wi-Fi Range Extender?

From physical obstructions like concrete and brick walls to electronic gadgets, other wireless networks, and Wi-Fi-based devices as well as the distance you are at from the wireless gateway or router—all these factors impact the strength of your in-home Wi-Fi network. That is why it is so often that you run into dead zones in your own house.

A Wi-Fi range extender is a smart and powerful device that picks up the Wi-Fi signal from your AT&T (or any other) wireless gateway device/router, amplifies it, and rebroadcasts the boosted signal. While it's challenging to have consistent Wi-Fi signal strength in a big-ish house, Wi-Fi signal boosters simplify the process and get the job done for you.

Whether it is a Wi-Fi range extender, signal booster, or repeater—all these devices are designed to enhance the wireless signal strength, eliminate dead zones, and ensure you get to enjoy the quality online experience that you’re paying for.

So, if you’re someone who is constantly moving around the house, a Wi-Fi range extender is bound to become your best friend. Whether it’s streaming your favorite Netflix show or smacking down a win in an online game, with Wi-Fi extenders, you don’t have to worry about losing the signal.

How Do You Choose the Best Wi-Fi Range Extender?

For your Wi-Fi extender to work effectively, some important factors must be considered.

Wi-Fi Standard Compatibility

Wi-Fi Standard compatibility is the foremost thing to take into account. The 802.11 Wi-Fi standards coordinate the distribution of data and determine the speed of data transfer between the AT&T Gateway and your wirelessly connected devices. These Wi-Fi standards started getting rolled out in 1999 and the last one was introduced in 2019. During the in-between 2 decades, 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, and 802.11ax have been rolled out.

So, when you pick Wi-Fi range extenders, you must make sure they are compatible with the Wi-Fi standard your AT&T gateway runs on. Check the specifications of your AT&T gateway device before you set off to make a purchase, or else pick a universal extender that works with 802.11b/g/n/ac gateways. Buying an extender without knowing if it's compatible with your AT&T gateway can turn into a total waste of your money and time.

Radio Frequency Bands

It is also necessary to decide whether you would want to use a single or dual-band extender. Most Wi-Fi range extenders work on a single band—2.4GHz. But, you can also get dual-band ones, at a slightly higher price. It is up to you whether you would like to take advantage of both the 2.4 and 5GHz bands that the AT&T gateway device has to offer.

Desktop or Plug-in

Make sure you are clear about what you want from the physical outlook of your Wi-Fi range extender—do you want one to place on the desktop or you’d rather get the plug-in one. Wall-mounted plug-in Wi-Fi range extenders take the least amount of space because all they need is a free power socket on the wall. Here it is worth mentioning most advanced Wi-Fi extenders are designed for the desktop.

Moreover, see whether or not you want the gadget to come with external antennas or built-in, and if you would rather go with a dual-antenna Wi-Fi range extender.

When deciding on this aspect, remember the ideal location for a Wi-Fi range extender is between your wireless AT&T gateway and the dead zone you are trying to eliminate. It is also necessary the extender is placed within good range of the wireless gateway. So, do take a look at probable locations in your home, and pick the Wi-Fi extender that fits into the scheme of things as you have it.


These days almost all Wi-Fi range extenders support WPA2-PSK security protocol which defines the highest security level available to home users. But it is better to be safe than sorry so do check to confirm if the extender you are picking will keep your in-home Wi-Fi network secure.

The AT&T Smart Wi-Fi Extender(s)

AT&T provides subscribers a gateway device depending on the kind of connection they have, and the speed plan they need to support. This way AT&T is able to ensure the internet equipment is fully compatible with its connection, and you are able to reap the full benefit of your AT&T internet service. There is quite a variety of modem-router combo devices—gateways—that AT&T furnishes. These devices use advanced mesh technology to give you wall-to-wall coverage via the best and the fastest connection available. But, for whole-home coverage it is recommended you pair the AT&T gateway with AT&T Smart Wi-Fi Extender(s)—do make note of the fact the Smart Extender(s) can be paired with these AT&T wireless gateways only: NVG599, 5268AC, BGW320, and BGW210.

AT&T offers two versions of the AirTies Smart Wi-Fi Extenders: AirTies 4920 Smart Wi-Fi Extender & AirTies 4921 Smart Wi-Fi Extender. And, the provider recommends if you wish to take full advantage of all the features of the AT&T Smart Home network and the Smart Home Manager app, you use AT&T-branded AirTies extenders only. Here it is worth mentioning these AT&T Smart Wi-Fi range extenders may not work with non-AT&T-branded Wi-Fi gateways or another ISP’s service.

Now, if you have used your Smart Home Manager to determine AT&T Smart Wi-Fi Extender(s) can help eliminate Wi-Fi dead zones in your house, we’d recommend you take a look at some key features of these amazing gadgets.

Is My AT&T Wi-Fi Booster Working?

Since by adding the new AT&T Smart Wi-Fi Extender your in-home network info does not change, the network does not appear with a new name on your device(s). But when the light on the Extender turns solid green, it tells you the pairing is done and the gadget is working. You can also use the Smart Home Manager app to check if it is working. The AT&T Smart Wi-Fi Extender shows up in the Devices section when connected.

For the Extender to work effectively make sure both radio bands—2.4GHz & 5GHz—are enabled.

Troubleshooting your AT&T Smart Wi-Fi Extender

If you see a solid red light on the Extender it means there is a pairing error. Try to pair with WPS again. Or else use the Ethernet cable to connect the Extender to the AT&T Gateway and pair the two devices manually. In case the issue persists, you may have to troubleshoot the AT&T Gateway device.

  • Check all cables and connections to determine if they are well in place.
  • If yes, begin with the manual reboot of your AT&T Gateway and Extender.
  • Unplug the power cord of your Wi-Fi Gateway and leave it unplugged for about 15 seconds before plugging it back in. Then do the same with the Extender.
  • You may have to wait for up to 10 minutes for the Gateway and the Extender to completely reboot.
  • If the issue is not resolved, check the status of the service with AT&T.

When you see a flashing red light, it means the Extender is out of the range of the Gateway. Move it closer to the gateway device or another connected Extender. That should resolve the problem.

Other High Performing AT&T Wi-Fi Extenders
