Att Fiber having multiple disconnects every 15 mins involving multiple homes on my street.
Hello bit of a long post but please bear with me. and thanks in advance here goes.
I've had att fiber to the house since 2017. Originally the way it was installed - Direct Fiber Line straight from a pfp up the street, to the house that was connected via an outdoor ONT that converted the fiber to copper then to an indoor pace gateway, up until three weeks ago this was great and no issues. I work from home and noticed a problem one day while working, the internet would just drop out for a split second and pick right back up. No lights change on gateway, Just long enough to drop me out of whatever call or meeting that I am in and I'd have to rejoin. After ruling out all equipment/wiring I started calling Att.
Fast forward multiple phone calls to tech support, constant restarts of gateway due to what they refer to as "policy mismatches", replacing the gateway to a newer bgw310 then to actually have my first tech come out and reterminating the fiber at each end. still no dice problem still occurs. The last tech actually did away completely with the outdoor ont and now I have fiber ran inside the house directly to the BGW320 ONT/GATEWAY in one.
Issue still the same no changes. From the first few calls to now, In that time I came across a program that I used to ping 3 websites constantly for 24 hours straight an it created logs each fail and I noticed it was disconnecting then reconnecting from the isp for anywhere between 2-5 seconds at a time, every 15 minutes on the hour. ex. 8:00 8:15 8:30 etc this happens around the clock. This happens on wired connections also wifi and I've also verified that this occurs at least two different neighbors homes. So it is definitely a Att issue that the techs cannot seem to see on their end to address.
I've had a total of 4 techs out at this point and they see the issue when I show them but don't see anything wrong when they test the line. Its been passed onto two different departments already. I've searched forums online for hours and found quite a bit but still no other with this exact issue. I suggested to the tech on one forum post that I read about a similar issue possibly stemming from a bad "card" or splitter that feeds the pfp on my street and they agree that it maybe that but can only put tickets in for service on those if the service is "Dark" or completely out from what I understand.
Has anyone here had this happen and can give any advice? I'm not expecting a miracle and I know it's a long shot. I just thought that maybe sharing this may find someone that can point me in the right direction or even eventually provide help to someone in the future to have something when "Googling" a similar issue. If it does get fixed before I jump ship I promise to update here. I hate to have to go back to the old slow coax cable company.
