For many people, outages and interruptions in the internet connection can be a total nightmare. This is because everyone relies on the internet in one way or the other to get things done. It could be to browse the web, shop online, check emails, or do some freelance work. With that said, some common problems can affect the internet connections in your home. For instance, what does the red light flashing on your AT&T router mean? What do you do when you see a red light flickering on your router?

The truth is a red flashing light or red globe on the AT&T router is a common issue internet users tend to experience nowadays. It means that there is really no internet connection. Therefore, you will find that none of your internet devices are connected any time you see this. On that note, there are various causes of the AT&T broadband red light flashing.

The first thing to keep in mind before troubleshooting a flashing red globe on your AT&T router is what the problem actually means. The flashing red globe is an indication that a broadband signal has been detected, but there is no connection established.

What do the lights on my AT&T router mean?

Before we can discuss more about the red flashing light and how to fix it, we must understand what the various lights on the AT&T router actually mean.

  • Flashing red light-a broadband signal has been detected, but there is no connection established.
  • Solid red- there is absolutely no signal on a line.
  • Flashing green- the device is in the process of powering up or attempting to get a broadband connection.
  • Solid green- good and strong broadband signal.
  • Flashing yellow- the LTE device is in place, but it’s not operating properly.

Things to do before troubleshooting the red flashing light on the AT&T router

A flashing red globe is bound to cause your internet connection to go down. People find themselves panicking because they have no idea of what to do in this situation. Well, there are actually a few things that you can do to try and get rid of the problem sooner. It might turn out that it’s only something small that is behind all this. So take a deep breath and try out the following;

Upgrade the router firmware

It might be that your router’s firmware is outdated and hence the red flashing globe. Simply input your router IP address into the web browser. You will be required to enter your signing in credentials. After that, there will be an update section available to you. Click on it to download up-to-date firmware on the manufacturer website. Upload it to complete the action. Check whether the flashing red globe has disappeared and turned into a solid bright white light.

Move your router

Oftentimes, the red flashing globe is due to an extremely loose connection that can’t sustain a stable internet connection. The cause of this may be an improperly positioned router. By this, I mean the router is in a location that receives extremely weak signals to the point it shows the red flashing light. If that’s the case, try repositioning your AT&T broadband router in another location away from it’s previous.

Avoid any interference

The flickering red light might also be as a result of many interferences with the signals. If your AT&T router is kept close to a bunch of interfering objects, it might be extremely difficult for the signals to generate and hence the red flashing globe. Remove any obstacles out of the way or put them away from the router. Microwaves, cordless phones, and washing machines can also be a major interference of signals.

Check for overheating

Just like any other device, routers are also prone to overheating. You can simply touch the router to feel if it’s too hot. It might be that it’s overheated and therefore, can’t function the right way and generate signals as needed. That might be why there is a red flashing globe showing on the router.

How to fix the AT&T broadband red light flashing

Supposing you have already relocated the router, upgraded the firmware, and moved it away from the common obstacles; what is the next step to take? You will need some troubleshooting solutions and tips to get rid of the red flashing light finally. For starters, when the broadband light on your AT&T router flashes red, it might be a strong indication of an issue with the cables connected with your modem.

Other than that, the problem might lie within your physical network. It’s now up to you to find effective ways of resolving the flashing red light and eventually get back online. Luckily, we are certainly here to help you through every notable step. Here are some helpful tricks worth trying;

Restart gateway

The first thing that you should do is to unplug the power connection to the gateway for at least 15 seconds. This should give it enough time to rest and cool in the case of overheating. Afterward, plug it back in and check if the broadband light has gone from red to green. This can take about five minutes. That said, ensure the connection is well established and back to the way it’s supposed to be. This solution works most of the time, but there is also a small chance it won’t get rid of the red globe.

Reset your AT&T modem

Resetting the modem has been a lifesaver in many situations that involve the internet. It almost certainly works regardless of the problem at hand. Thus resetting your AT&T modem might be the most viable solution in getting rid of the red flash light. You have to gently press and hold on to the reset button located on the modem’s rear end for about 30 seconds. Release the hold once the light turns from red to green or a solid white.

You can also decide to log into the modem and reset it. Though keep in mind resetting the modem will return the gateway settings to default. This means that any passwords, wifi usernames, static IP, and SSID will be lost.

Check for loose connections

Check all cables and connections to see whether there are some which are loose. The connection might loosen if someone bumped into it and forgot to check. It could be that some cables were unplugged by mistake. Plug them back in tightly and to the right broadband port.

To ensure a smooth connection, remove the surge protectors, battery units, and any other equipment to give way to a direct connection. In addition, examine the cables for any signs of wear and tear. If the cables are old and worn out, replace them with some new ones. A bent cable or one that is pressed tightly against a sharp object can also be the reason why there is a red flash globe on your router. Rectifying all these restores the green or white light.

Change the connector

Unless you are a technician, it isn’t easy to know things such as the connector. At the end of the broadband cable, there is a plastic connector. This works as a connection between the broadband cable and the router or modem. What you need to do in this case is closely examine the broadband cables and see if there are damages or it is not functioning properly. If you suspect the connector causing the problem, change it, and connect a new one at the end of the cable. It might help eventually solve the problem.

Reset it back to factory settings

Any of the above solutions can work to restore the solid green light on your AT&T router. However, in case everything else fails, there is still a viable solution for you. You might have unknowingly messed up the settings on your router or modem. If it’s not you, there is a likelihood an application you installed on your PC or laptop is the culprit.

If you can still connect the modem to the internet, check its settings and rule out anything blocking the communication to your broadband cable. Are there any settings that might be causing the router to show a red flashing globe? If yes, then it might be worthwhile to reset your AT&T router or modem to factory settings. Afterward, it will start functioning well.

Check for outages

A sudden power or internet outage can affect your router’s functioning and ultimately cause the red flash globe. If you are not sure there is an AT&T internet outage, you can check their outage site for updates on the same. On the other hand, storm or heavy rains might also affect the internet and cause problems. This is especially if the service drop occurred at around the same time as after a power loss or storm.

Contact your service provider

This is usually the last resort after trying everything else in vain. Simply contact your ISP customer support for further guidance and assistance. There is a possibility the servers on their end are down, and the modem is unable to connect. It might also be issues with the wires on the other end that are making the AT&T router show a red flash globe. Well, it won’t take long before your ISP customer support diagnoses the issue and provide the best solution to the problem. The flickering red light will go away in no time and get you connected to the internet.

What does AT&T do when there is a red flash globe on my router?

First and foremost, you are advised not to skip any of the steps or solutions provided when trying to get rid of the flickering red light on the AT&T router. Furthermore, there is an AT&T troubleshooting tool to help arrive at a solution. Aside from that, when the company checks and finds out there is an issue on their side, they will do all they can to rectify it as soon as possible.

In case you can’t solve the issue on your own, you can set up an appointment with a technician from AT&T. Depending on the issue, the problem will be solved sooner than later.
