Att Router Not Working


I switched to a new internet service provider a few months after hearing about the fantastic customer service and fast internet AT&T offers. I was extremely pleased with the services for the first couple of weeks. But after that, I began to experience some speed problems. I wasn’t certain what the issue was. I attempted to restart the modem, but it did not succeed. I concluded that the peak rush hour was to blame after exploring online for potential causes of why my internet was giving me such a hard time.

My internet connection was smooth during the day but slowed down in the evening. So everything made sense. There are, however, several additional causes for your sluggish or intermittent connection. I’ve mentioned some tried-and-true solutions in this article to assist you in comprehending the problem and troubleshooting the connection.

Restart the modem to troubleshoot your AT&T internet connection. Try WiFi gateway or hard resetting the router if this doesn’t work. This will take care of any issues or errors.

In addition to this, I have also discussed various troubleshooting techniques, such as looking for any loose connections.

Reasons Your Internet Connection Is Not Working Properly

A variety of things may cause a slow internet connection. Among them are:

A service interruption or downtime

  1. Since AT&T serves millions of customers, they must perform routine maintenance to maintain the promised internet speed.
  2. There’s a potential that your internet won’t function normally at this period.
  3. Getting in touch with AT&T customer service is the easiest way to determine whether there is a service interruption.

Restart your WiFi router and AT&T modem.

More than simply a joke, “Have you tried turning it off and on?” is one of the finest tricks for getting a slow modem/router (or gateway, as AT&T calls it) back in working order.

Rebooting your gateway tells it to address any small bugs that might be hindering its performance.

Remove the power cord from your modem or router, wait 60 seconds, and then plug it back in. Restarting a modem or router is routine maintenance that should occur more frequently than you might imagine, just like rebooting a computer (like every month or so).

Find the name and password for your AT&T WiFi network.

Can’t remember your WiFi password after being logged out? Or even worse, do you forget which of your neighbors’ WiFi networks is yours?

The login information and password might be printed on the modem/router if you didn’t alter the default credentials during the first setup. Log in to your AT&T account for a review if you rename your WiFi network and create a new password (hopefully, you remember your account credentials).

Repairing your AT&T internet connection

Indicators of AT&T internet service issues outside of your WiFi network include slowed speeds and dropped connections. It’s them and not you.

Test your internet speed

Ever questioned whether you were receiving the promised internet speed from AT&T? Test your internet speed. Run tests at various times of the day because speeds can change during peak neighborhood traffic hours depending on the connection type (DSL or fiber-optic).

Reset your internet gateway from AT&T.

You can execute a full reset on your AT&T modem/router or gateway if you’ve already attempted the power off/on the trick. Any customized settings, like your WiFi network name and static IPs, will be erased by this, but they can be recovered later.

Like restarting your modem or router, a complete reset will fix performance issues and improve security protection by removing malware and changing compromised passwords.

Steps for resetting your AT&T router

  1. For 10 seconds, press and hold the reset button on the gateway. In less than ten seconds, it will simply reboot.
  2. Watch for the indicator lights on the gateway to turn back on.
  3. The reset is finished when all the lights are green.
  4. Your internet-connected devices should restart.
  5. Restarting your internet-connected devices can help resolve connection issues like turning off your modem, router, or gateway.

Restart your internet-connected devices, including your PCs, laptops, tablets, phones, TV streaming equipment, and other mobile devices (and update them if necessary). This will release more computer power by refreshing systems and clearing caches.

Verify an internet outage on AT&T.

The my AT&T app (available for iOS and Android) on your phone allows you to check if AT&T service is unavailable in your location (because, of course, no internet). You can also use AT&T’s outage page to search for outages if you don’t want to use another app.

Know What the Modem’s Lights Mean

The lights on your modem can be useful if you are having trouble diagnosing the root of a poor internet connection.

Every light denotes something distinct.

For instance, a solid green light indicates that the internet is operating normally, whereas a flickering green light indicates that the router hasn’t been powered.

You can get comprehensive explanations of what each LED on your modem means on AT&T’s help page.

Analyze Any Lost Connections

  1. Loose connections and damaged wires can also impact the speed of the internet.
  2. Therefore, check for any loose connections or damaged cables before concluding that the ISP is to blame for the slow internet.
  3. These can be risky and affect the internet’s performance and speed.
  4. Examine the ports and jacks where the cables are plugged in and the power plug to ensure it is supplying enough power.

Has your internet bill been paid?

Internet bills that haven’t been paid are frequently to blame for poor internet connectivity.

It’s possible that your subscription was terminated because you failed to pay your internet bill.

Check whether your internet bill has been paid to ensure this is not the case. You can do this by logging into your AT&T account or by calling customer service.

Start the router again.

  1. Restarting a device is the first thing you should do if it isn’t working properly.
  2. Restarting the computer will fix any faults or malfunctions by refreshing the system.
  3. The same is true for your modem or router. Many problems can be resolved with a reboot.

The procedures below to restart your router:

  1. Plug the router out of the power supply.
  2. Allow 120 seconds to pass.
  3. Connect the device once more.
  4. Hold off until it restarts. This could take some time.

Speak with customer service

If you can still not identify the cause of your sluggish internet connection and restarting the router did not help, keep reading.

Time to get in touch with AT&T customer service. You can call them at their toll-free number or use their live chat function to communicate with them.


If you can identify the reason for any internet connection problems, they are all rather simple to fix.

Network adapters that are out of date can also be problematic. Your PC can communicate with other internet-connected devices thanks to a network adapter.

You will have a shaky internet connection if your network adaptor is out of sync with the gateway device.
