You’ve got 99 problems, and AT&T internet outages accounts for one—we feel you. In the case of AT&T service, we can help, but you’re on your own with the other 98.

We’ve done the research and come up with some easy fixes for everyday AT&T internet problems and service issues. For more complex problems, we’d suggest calling AT&T customer support (or maybe even Jay-Z).

Troubleshooting your AT&T Wi-Fi

Is your AT&T Wi-Fi not working? Wi-Fi problems are the most common source of internet frustration, second only to incessant rating requests. Here are some quick Wi-Fi fixes that deal with your network connection, minor modem and router bugs, and that ole chestnut: your password. (If you like what you read, please leave us five stars.)

Reboot your AT&T modem and Wi-Fi router

“Have you tried turning it off and on?” is more than just a meme—it’s one of the best tips to reset a sluggish modem/router (or gateway, as AT&T calls it) to working order.

Basically, by rebooting your gateway, you encourage it to fix any minor bugs that might be slowing down its performance.

Unplug your modem/router from its power source, wait 60 seconds, then reconnect the power. Like rebooting a computer, restarting a modem/router is routine maintenance that should happen more often than you think (like every month or so).

Find your AT&T Wi-Fi network name and password

Logged out of your Wi-Fi and can’t recall the password? Or worse, you don’t remember which Wi-Fi network is yours amongst the neighbors’?

If you changed none of the credentials that came with the modem/router when installed, the login and password could be labeled on the device. If you did rename your Wi-Fi network and/or came up with a new password, log in to your AT&T account for a refresher (hopefully, you remember your account credentials).

Troubleshooting your AT&T internet service

Slowed speeds and dropped connections are signs of AT&T internet service problems outside of your Wi-Fi network. It’s not you, it’s them.

Take an internet speed test

Ever wondered if you’re getting the internet speed AT&T advertised? Take an internet speed test. Depending on the type of connection (DSL or fiber-optic), speeds can vary during heavy neighborhood traffic hours, so run tests at different times of day.

Pro tip: Keep in mind, Wi-Fi will usually deliver lower speed numbers than a direct Ethernet connection to your device. The age of your device can also slow your speed, as older gear operates with lower-quality Wi-Fi receivers. Unfortunately, tech is a never-ending game of ABU (always be upgrading).

Factor those, do the math—is your download speed dramatically less than what you were sold on? It might be time to find a new internet provider.

Reset your AT&T internet gateway

If you’ve already tried the power off/on trick with your AT&T modem/router or gateway, you can perform a full reset. This will wipe any custom settings, like your Wi-Fi network name and static IPs, but they can be restored after.

A full reset will clean up performance issues like rebooting your modem/router does and give you added security protection by disrupting malware and switching up hacked passwords.

How to reset your AT&T router

  1. Press and hold the gateway reset button for 10 seconds. Less than 10 seconds will just reboot it.
  2. Wait for the gateway’s indicator lights to come back on.
  3. When all lights are green, the reset is complete.

Restart your internet-connected devices

Like turning your modem/router or gateway off and back on, rebooting your internet-connected devices can also clear up connection issues.

Restart (and update, if necessary) your computers, laptops, tablets, phones, TV streaming devices, and whatever else you may have connected to the internet. This will refresh systems and clear caches, freeing up more computing power.

Confirm an AT&T internet outage

You can check to see if AT&T service is down in your area through the myAT&T app (Android and iOS) on your phone (because, of course, no internet). If you don’t want another app, you can also look up outages through AT&T’s outage page.
