AT&T Fiber Frequent Disconnects

@wydeng you should note that browndk26 uses his third-party wireless router in Access Point mode, and thus IP Passthrough is inappropriate for his configuration.  If you're using your Wireless Router as a router, then IP Passthrough is appropriate.

If you were using your Router as a router without IP Passthrough, then that would have caused some issues, though DHCP handling on the Gateway would not have been a reason for that.

@JefferMC My old setup was using my own router as AP, BGW210 as router. New setup is using my own router as router, BGW210 as passthrough. In the old setup, wireless device (cellphone) sometimes couldn’t connect to internet. If I tried to go to 192.168.1.254 (gateway IP) in the browser on my phone, it would hang. However, once you are connected and keep using internet ( watch YouTube, etc.), the internet never drops. That’s why I suspect it’s routers DHCP function (or router side function) problem. Basically the first connection can be difficult.

I will stay put with correct setup until problem arises:-)

 Thanks for your input.

@cmagrp , it is possible for interference generated by an inferior power strip/surge suppressor to cause line noise, and because of that it is in AT&T Support's script book to plug directly into the wall.  TBH, that should not affect fiber reliability because of the difference between the way signals are processed between the fiber and the copper.  But if you want to try it so you can eliminate it, go for it.

My Gateway has nearly always been plugged into a UPS, and I'm on copper.

Update... after two years of calling out techs, the person I spoke to today told me that At&t provides the service and equipment but it is up to me to make it work. So, at this moment, I have a DVR that isn't connected to a TV because in order to make the internet work with a consistent signal throughout the house without devices falling off the wi-fi, I had to move the gateway to a central point in the house along with the mesh router and TV access point. So, the wireless set top boxes get a good signal and my internet and wi-fi is stable. But at the cost of having a room with a TV and no cable and DVR hooked to the gateway but no TV. So, I will now have to run tacky cables around the house or pay someone to 'network' my house. Let me not forget that I also had to purchase a mesh system to create a second network. While connecting the mesh as access points to the gateway gave me a strong signal, my devices kept falling off of the At&t gateway. And, as far as i have been able to find, you can't use fiber without the At&t gateway/modem. I was told I had too much on the wi-fi. So all my smart devices run off of the gateway's wi-fi and the mesh network runs everything else. It is stupid to me that I am having such difficulty making internet and cable work in a 1600sq/ft home, not a mansion. Had this been something I had known when I had the service installed that At&t's help stopped at giving me a line to my house and giving me equipment, I would have thought differently about how to deploy it. Maybe this is all something that is buried at the bottom off the commercial that flashes up for two seconds. It certainly wasn't part of the selling points when they so eagerly locked me into a contract. My larger complaint is that they wasted two years of my time just to say, we gave you service & equipment and we're done.

I get the same issue, I have random devices disconnect from the wifi. Having to restart the TV or the device connected is absolutely absurd when paying for Gig speed. Even if there was a bandwidth issue or too many devices, it should not even affect streaming or regular internet usage that much. We are talking 1000 MEGABYTES. You could have 10 devices and still push 80-90 on each and "SHOULD" have enough bandwidth. Now I called the techs, was lucky enough to have the issue while they were there. They tried a few different things and when he came out the 3rd time his answer was; "AT&T is only responsible for getting the service to your house. How it works once it's there is not our responsability". I cannot understand how in this world you can advertise no gaming lag, high speed streaming and download which is completely false if you don't manage the service within the home. Providing the proper wiring to the box, to the equipment etc. That all should be under the accountability of what you call an INTERNET SERVICE PROVIDER. I have had this terribly unstable internet for 2 years because apparently the special I had locked me in a 2 year contract, unlike what I was told when I signed it. Had to cancel my TV subscription and pay an "early termination fee" since I was also locked in to that. As we speak I am shopping around for another company that can live up to at least half of the promise of stable high speed internet. Reading through the whole thread, I can't believe it's been 3 or more years since this has been a norm, clearly customers have given up on trying to find the solution which is a disgrace to a company with such high capacity. $70/mo for JUST INTERNET should be worth a lot more than just "sorry, can you try to reset your gate way".
