AT&T Troubleshooting Guide
Learn some quick fixes to help keep your AT&T Wi-Fi, internet, and TV service humming.
You’ve got 99 problems, and AT&T internet and TV outages account for two—we feel you. In the case of AT&T service, we can help, but you’re on your own with the other 97.
We’ve done the research and come up with some easy fixes for everyday AT&T internet and TV 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
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.)
Check your network connection
Loose connections happen, especially when a curious cat is looking for a new chew toy (we see you, Duchess).
Check your Ethernet cables and power cords to make sure all plugs are secured. If they’ve been in place for an extended period of time, it also can’t hurt to replace an old cord with a new one—it’s a cheap upgrade.
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.
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 equipment
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 gateway
- Press and hold the gateway reset button for 10 seconds. Less than 10 seconds will just reboot it.
- Wait for the gateway’s indicator lights to come back on.
- 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.
Troubleshooting your AT&T TV device
Your AT&T TV device is internet-connected, so many of the tips listed above will also apply here. Yes, even kitty-gnawed wires.
Check your cables and connections
Does your signal keep dropping? Are you unable to watch your favorite channels? Are you slowly having a mental breakdown because your TV ain’t working? (We kid.)
Check the HDMI cable between your TV and the AT&T TV device first for a solid fit. If you’re using an Ethernet cable to connect the device to the internet (which we recommend when possible, as it’s a more reliable connection than wireless), check that next.
Also check the power cable. It’ll be more obvious if that’s not connected properly, as nothing will turn on, but you might as well be thorough.
If you’re using AT&T TV as an app through a third-party device (Apple TV, Roku, Amazon Fire TV, etc.), apply these same steps to that streaming device.
Refresh the signal to your AT&T TV device
It really does work for everything because home electronics, like your TV device and gateway, all need a good cleaning now and then to get them running properly again.
You can restart your AT&T TV device by pushing the red button on the side of the box or unplugging the power cord and plugging it back in. You can also run network diagnostics through Settings.
You also might want to restart the internet modem/router or gateway at the same time, just to make sure all connections are simultaneously refreshed.
Troubleshooting your AT&T TV app
Watching AT&T TV on the mobile app? You’ll be better off with the latest updates installed (ABU can also stand for always be updating) to optimize your viewing experience.
Update your AT&T TV app
Your phone or tablet will probably update the AT&T TV app automatically, or at least tell you it’s time to download the new version. Hit the Android or iOS store and install away.
Uninstall and reinstall your AT&T TV app
If the app seems especially uncooperative, it might be best to uninstall it entirely and perform a new install. Don’t forget to restart your phone or tablet, as well (we know, so much rebooting).
Check your parental controls
Can’t view certain content on AT&T TV, either through the AT&T TV device or the app? You may have parental controls activated.
How to activate parental controls
- Go to Settings
- Click on Preferences
- Click on Parental Controls
- Set up a four-digit pin number
- Activate (or deactivate) the parental restrictions
And remember: Parental Controls don’t carry over between devices; each one has to be set up individually.
