Re: Wireless Keeps Dropping Connection

Hi, @Tukebird.


We've put together some Wi-Fi troubleshooting tips to help with intermittent connections. Here is a quick tip, try restarting your gateway.

  1. Unplug your gateway for 15 seconds.
  2. Remove and reinsert the battery, if you have an internal battery backup.
  3. Plug the gateway back in and wait for the lights to stop flashing.
  4. Check your connection to see if the problem is fixed.

If this does not correct the service connection error please read through the article linked about for more tips. Let us know how this works for you.

Re: Wireless Keeps Dropping Connection

I've just had a U-Verse tech over to the house (knowledgeable) and had him trouble shoot our wireless that has become ineffective. He updated (2) extenders for us, added a new router, and a couple of boosters for the video signal...still....signal keeps dropping in the back master...and even in my office next to the router. While sitting here going through various steps with the AT&T home management portal....I had to "enable" the wifi 2.4g at least (6) times in the past hour as it keeps dropping out. I have read all of the threads, and realize that it's dual band between 5 and 2.4.....but I am more interested in coverage than speed. I thought our problems over the past couple of months were behind us with this.....guess not.

Re: Wireless Keeps Dropping Connection

Best coverage is 2.4Ghz at half the frequency of 5Ghz. However has fewer channels (1-11) and more prone to wireless interference from other devices, especially in close living quarters such as apartments, condos. 


Recommend using an android device, preferably dual band, and free app wifi analyzer (radar sweep icon). After scanning, change the channels on your gateway.


Next do you have hardwired connection to pc or laptop? When wifi drops, does hardwired device still have internet connection? 


My thought is crowded wifi environment, gateway keeps changing channels resulting in a drop to wireless devices. If hardwired device(s) also drop suggests signal issue to gateway.


Do you have Uverse IPTV service? If yes, are the receivers losing service as well?


Edit... Problem could also be caused by power issues such as bad ac power, noise on ac line, Foreign Voltage from improper or no grounding of power, etc. 


For most gateways with coax connector the gateway can be grounded using 442C and if ac outlet is actually grounded. Not an option on 210-700 gateway or 510 or 5031.

Re: Wireless Keeps Dropping Connection

I have the same problem - been ongoing for months.  Gateway's replaced, WAP replaced, wireless tv boxes replaced - no luck.  I had an in home consultant from ATT out to tell me that it could be the location of the WAP (been moved to 3 different places)  voltage surge as it is near a refrigerator, mice chewing on wires at night, etc.  Took no ownership and when I explained why each theory didn't hold water told me to call the service department and left.


I've called the service team and said since they can'f fix my wireless receiver issue to hard wire the two television boxes.  I'll let you know if that solves the issue.

Re: Wireless Keeps Dropping Connection

We have had ATT Uverse for 5 years now and really never had any problems. About 3 months ago we started having the WiFi Gateway just stop. All the lights go off and anywhere from 3-5 minutes, and at least once a day sometimes 4 or 5 times a day. It then reconnects and things start working. My computer is hardwired into the gateway, everything else is on WiFi. Nothing works for that time period. It is very annoying to be watching TV or be on the computer and for no reason it just cuts off. I am not a techy person so what I would like to know is could this be my Gateway/router getting old and needs to be replaced? It is 5 years old and used a lot. P.S. How do I know if I have an internal backup battery? I see some instructions say unplug and take out battery if you have an internal backup battery> I have a backup battery thing if the power goes off but I am not sure if that is what they talk about when saying to reboot.
