AT&T Wi-Fi Connected But Not Working (Troubleshooting AT&T Wi-Fi)

Even after buying the fancy gateways from AT&T, you are not getting access to the internet. That sucks! Why does this kind of thing happen even after spending so much money on big brands and their supposedly ‘quality’ products?

Well, don’t lose your mind over this one. Even after so much scientific advancement, humanity still has to figure out what to do with entangled cables and power outages. So, expect that these interruptions in your internet connections will keep happening.

And there is not one big reason why you can’t access the internet even after your AT&T Wi-Fi is connected. Let’s sort out all of the possibilities one by one and see which step gets you out of your issue.

AT&T Wi-Fi Connected But Not Working

The More You Know 

AT&T is the largest telecommunication services provider in the world right now with over 77 million people accessing its post-paid services while around 18 million folks using the pre-paid ones (this data is of 2019).


Let us first rule out the most common situations why you can’t access the internet even after an AT&T Wi-Fi connection.


  • Power On or Off?

Ok, this might seem pretty basic to the point of you feeling like we are insulting your intelligence, but trust us, many need to hear this one. Make sure that your building has power running. That’s it.

Also, please save this page for ‘offline read’ in the future if you are an AT&T user and you lose your shit easily.

  • Balance?

Have you run out of your plan? Have you, by any chance, consumed all your quota or something? Make that sure and refill.

  • Maintenance Issue?

AT&T could be working on something in your area and that is why the internet is disabled. Make sure that your neighbor or anyone else who also uses AT&T is facing the same issue as you are.

  • Weird Outage

Sometimes, for some very ‘final destination’ like reason, your God has made it so that you alone in all of the world must not get your sweet-sweet internet. Also called an outage. Check with another AT&T user to see if this is the case and if it is, wait it out or call your ISP.

  • Load?

Look, if your in-house network, your AT&T gateway is doing overtime, like providing internet to five of your fam who all are playing Fortnite with ultra HD specs on, then my dude you are going to face internet problems.


All right those would be the most obvious and simple reasons, and if they do not work then let’s pull out some bigger punches.


  • Bad Placement

Weird as it may sound where you place your router/modem decides heavily how well your connection is going to be!

So, make sure that:

  • Your wireless router/gateway is at a central location of your house
  • Keep it at least 3 feet away from other machines that can also send wireless signals (oven, baby monitors, cordless phones, etc.)
  • Your gateway isn’t too near to the floor
  • Avoid physical obstructions, nothing should ‘cover’ your router.

Ok, now, we move on to the actual steps that you can nudge with and hope to your god you don’t have to call ISP support.


  • Power Cycle

Ok so unplug your AT&T gateway from the socket, wait 2 whole minutes now, and plug it back in. Turn the thing on, this should work.

  • Hard Reset

The factory reset or hard reset is a really helpful option whenever you get internet disruptions. Just press and hold the reset button on your router till all lights go off. Wait a minute, and then hard press it again. This should do it.

  • Power Cycle Again

This time, try this method on your PC. Turn it off, wait for a whole minute, and then turn it back on. Worked?

  • Check Cables 

Ok, so simply speaking make sure even after everything seems ok that all the cables, and I mean ALL of them that are supposed to be going into your gateway are well connected. Pull them out and stick them back in, just to be sure.

  • Damaged Cables 

If you have spare cables, then check by replacing the old ones with new ones and see whether things are working now. Damaged cables could also be why you are not getting internet, and figuring this issue out is a bitch.

  • Third-Party Routers

Try disconnecting your third-party router (D-Link or Linksys etc.). If this works, then you should probably call the equipment manufacturer to help you set up your home network with a TPR.

  • Thy Filters

Make sure that filters are installed on every phone jack with a telephone device connected to them like fax machines, answering machines, etc. 

Also, the phone line that is connected with your AT&T gateway must be directly plugged into the phone jack or the DSL/HPNA side of the filter.

  • Wireless Settings

If you are using a wireless connection, make sure your wireless settings are set up properly. In doubt, reset your network settings in your phone or PC and then restart them. Check our various articles on this issue here.

  • Cookies and Caches

Try cleaning up your browser’s cache and the browser cookies. This should help a little. Do this nonetheless, internet issue or not, frequently.

  • Virus and Anti-Virus 

If your device has contracted viruses, malware, spyware, or something like that, then run a powerful and effective antivirus scan to troubleshoot this issue.

Sometimes the antivirus installed in your device could also interfere with your internet access. Try disabling that if you think your device is safe to do so.

  • Disruptions in Network

If you have used the wrong username and password to make a Wi-Fi connection, that could be the issue. Forget your Wi-Fi settings. Then reconnect using the right username/password.

  • Inferior Gateway

Buy a newer model of AT&T gateway. If yours is old, then you could have internet access issues.

  • Parental Control

Go to the access page of your gateway using its IP address. In the Settings, turn off your Parental Control.

  • The USB Port

If your network adaptor is using a USB then make sure that the adaptor is cool with handling gigabit speeds. For example – if you have a plan of 250 to 300 Mbps, then USB 2.0 is ok. But if you have like 900Mbps or higher, then switch to USB 3.0.

  • Corrupted Files

An excess of corrupted files could also drain your Wi-Fi speed. So, keep an eye out for those things from time to time.

  • Old OS/CPU

If you have an ancient set-up, then for the love of Harry Houdini pimp that shit up. Because the old setting won’t handle the fiber-optic high-speed internet.
