Losing Internet Connection Several Times An Hour

I am having my service drop out often.   I get a couple error messages when I run the troubleshooter one is "Windows could not automatically detect this network's proxy settings." but the most common one I get is "Windows can't communicate with the device or resource (primary DNS server)".  It does this on my phone, my laptop and my desktop computers. I have gone online and done everything suggested there, (DNS flush, changing the DNS server to Google, of course restarting modem and about 8 other 'solutions') and it still hasn't solved the problem.  I think it is some setting on my computers that is causing this because I had a different ISP before ATT and had the same problem.  The dropouts with ATT don't last as long as with the cable people but it still persists and has gotten worse as time goes along it seems. Is there anyone that can help me?

We're here to help @SugarBalls

 

Here are a couple things you can check:

 

  • Restarting your gateway or modem, and reconnecting to your network after rebooting.
  • Are all your devices up to date with there software?
  • Also, are there any third party equipment, as in a router behind your AT&T router, switches or hubs?
  • We would also suggest checking your proxy settings

 

Please us know so we can further assist you.

I'm having the same issue. I can reset the modem (press power button for approximately 4 seconds) and regain connection, only to lose it again a few minutes later. On bad days I reset it 7 or more (I lose count) times before getting usable service. On a good day I only have to reset it once. All devices are updated and no 3rd party hardware is in use. 

 

If I fully reset the modem, won't that erase my DVR recordings? That's the only reason I haven't tried that. But the wi-fi is pretty much unusable for hours on some days, and there's not much point in paying for a service I can't use.

Hello @akn19,

 

We understand how frustrating this must be, let’s get your connection stabilized.

 

To begin I would like to inform you that resetting your internet modem will not erase your DVR recordings. With that being said lets follow these steps to get this fixed.

 

To ensure you Wi-Fi is healthy and optimized we recommend the following

  • Keeping the modem free and clear of electronics
  • Moving the modem off the floor and placing it on a hard surface
  • Plugging the modem directly into a wall outlet
  • Having the modem out in the open for proper air circulation

If you have the same troubles after ensuring your modem is in a good location we recommend trying out our Smart Home Manager app. This app has lots of great features that will help maximize your Wi-Fi.

  • Personalize network name and passwords
  • Run network health checks
  • Check for Wi-Fi dead zones and find out if your home could benefit from AT&T Wi-Fi Extenders for total coverage
  • Technical support built in with Smart Assistant

After that if you notice the same connectivity issues we can try the following.

  • Restart modem
    • Unplug the power for 30 seconds
    • Plug back in and wait for the broadband light to turn green, this can take 2-5 minutes
  • Reset the Modem
    • Press and hold the reset button located on the rear of the modem for 30 seconds.
    • WARNING: This will return all gateway settings to a default state. Any custom Wi-Fi passwords, Wi-Fi names, SSID, Static IP, and Port Forwarding rules will be lost.

We hope this helps @akn19, please let us know if we can be of any further assistance.
