Why is my AT&T Wi-Fi Not Working?
Many factors can contribute to AT&T Wi-Fi problems. From service outages and poor Wi-Fi signals to faulty hardware, it can easily affect the stability of your Wi-Fi network. Here are some of the reasons why your AT&T Wi-Fi is not working properly.
- Service Outages – Due to its wide reach of subscribers, AT&T will continue to improve its services and network facilities. Their scheduled maintenances will however lead to an unstable Wi-Fi connection. You can keep yourself updated on service outages near your area on their official social media pages.
- Weak Wi-Fi Signal – If you’re using your smartphone or device far away from your AT&T router, chances are it can cause abrupt disconnections. The typical indoor router has a range of about twenty meters but can reach up to 150 meters for more modern routers.
Your Wi-Fi frequency can also play a factor in signal strength. If it’s set on a 5 GHz frequency, your device typically needs to be nearer, compared to the default 2.4 GHz frequency, which is more stable.
- Poor Router Environment – If your router is surrounded by interferences, like microwaves, CCTVs, Bluetooth devices, and other Wi-Fi routers, your Wi-Fi router will have a hard time extending its signals to your device. These devices can compete with your AT&T router and limit its Wi-Fi signals.
Also, if you’re using your Wi-Fi router on the other side of the room, thick walls and other obstructions—such as mesh screens—can weaken the Wi-Fi signal and cause frequent disconnections.
- Damaged Wi-Fi Router – If your router has lasted for many years now without being replaced, chances are it may have hardware damage due to wear and tear. If you’re experiencing connectivity problems for a while, it’s best to call AT&T’s Customer Support to have it replaced. Outdated or damaged equipment can potentially be replaced by AT&T for free.
If your router lights are blinking or the AT&T Router is Blinking Red it could indicate a poor signal or power supply issue.
How to Fix AT&T Wi-Fi that Keeps Disconnecting
Now that you know some of the possible reasons why your AT&T Wi-Fi connection frequently disconnects, here are some common fixes that you can try. Remember to go through every fix and see which one works best for you.
Fix #1: Check All Connections on your Router
A great first step is to check all network cable connections on your router. See if each of them is connected properly and all cables are in good condition. It’s important to get old network cables replaced since they can greatly affect your network’s performance.
Also, check the power adapter for wear and tear damage. Disconnections can happen once your router doesn’t receive adequate power.
Fix #2: Power Cycle your AT&T Router
Restarting or power cycling your Wi-Fi router can help with most connectivity problems. This resets your router and all existing connections, therefore eliminating glitches that are causing this problem.
To power cycle your AT&T router, follow these steps:
- Turn off your router and unplug its power cord from the socket.
- Wait for twenty seconds for the router to drain some of its power. If it has an internal battery, remove it temporarily.
- After waiting, plug the router’s power cord back in and insert the internal battery if it has one.
- Turn on your router and try connecting to it using your smartphone.
- Browse the internet and see if your connection is stable.
Resetting your router should be enough to get the wifi connection back. We also have instructions on how to reset your AT&T TV Remote Control, too, if you need to.
Fix #3: Relocate your Wi-Fi Router
If your router is surrounded by various devices that cause interference, we recommend that you transfer it to a centralized, and unobstructed location in your house. This ensures that all Wi-Fi signals transmitted by your router will immediately reach your device.
Also, use your smartphone as close to the Wi-Fi router as possible, or keep your device at an optimal range. This way, your device will receive a stable Wi-Fi connection and eliminate any connectivity problems.
Fix #4: Set a New IP Address for your Computer
If you’re having trouble connecting to the Wi-Fi using your computer, you can try to release it and generate a new one via the Command Prompt. This will trigger your computer to access your Wi-Fi network with a new IP address.
To release your current IP address and renew it, follow the steps below:
- Right-click the Start Icon and select Command Prompt (Admin).
- Enable the User Access Control dialog box if it shows up.
- In the Command Prompt window, type the command ipconfig /release.
- Once the command is completed, type in ipconfig /renew to generate a new IP address.
- Close the window once completed and restart your computer.
- Connect to your Wi-Fi network and see if the connection is more stable.
