ATT Fiber Unstable Ping

Starting a month or so ago, my ping became very unstable when it comes to gaming. It would go from around 12ms to 300ms and cause very annoying lag spikes. I have contacted customer service twice. The first time, I was told there was an interference which they fixed. After a day, the issue came back. I contacted customer service again and the kind lady walked me through a process of restarting my router and switching the ends of my ethernet cable. She even said something about putting me on a new internet line. The ping issue was fixed for about a day or two, and today the ping spike issue came back. I have ATT Fiber 300 and I use a router the AT&T Smart Wi-Fi extender to connect the ethernet cable to because my cable is not long enough to reach the main router. I haven't had ping issues for a year. I was told it could be an issue with the router being old and I would have to get a new one. The router is ATT provided.

How is it you're measuring ping spikes when you're not gaming? 

Wi-Fi can have issues for a lot of reasons.  Nothing beats a solid Ethernet cable to the router, and you do not have that.

I don't measure ping spikes when I'm not gaming. I just noticed how when I'm browsing or watching movies/shows I never run into any issue. The internet is never noticeably slow and the streaming services never buffer. I can run an ethernet cable to the router, but it's just inconvenient and may be a tripping hazard since my PC and the router are not in close proximity.

So the better statement is that you do not notice ping spikes while doing anything other than gaming, and most of these other activities are not latency sensitive so you would not expect to notice ping spikes.

I understand why you don't want to run an Ethernet cable, but the fact remains that twitch games are latency sensitive and you'll notice issues over Wi-Fi that you'd never notice otherwise.  (I will say that maybe your latency issues don't have to do with the Wi-Fi, but we have no evidence in that direction at this point).  It could be that some new device is in your home and is causing intermittent interference.  It could be some old device in your home has started generating intermittent interference.  It could be that the radios in either your Gateway or Extenders are getting old and are starting to lose the ability to cleanly communicate with each other.   It could be that someone painted a wall in between the two and the extra 2-4 coats of paint are just enough to cause some issues.  Or you have a neighbor who just tweaked his Wi-Fi Router to boost power over FCC regs.  Or...

Same exact issue as original post. This isn't an isolated incident. I've managed to find others reporting the same thing around the same recent timeframe over the last month or so. Slowly ramping latency starting around 8EST, peaking to unplayable levels around 10EST, and gradually going back to normal around 11EST. The first time I noticed this, I did a speed test. Less than 1 down when I'm paying for 1000 down, slightly higher latency. The second time it happened I did another speed test. This time the speedtest was normal (but I was still having the same latency spikes in games). It's amazing to me that the root cause hasn't really been pinpointed yet. It's obviously happening to multiple people and implies a problem with the service itself, yet you have everyone running around trying to diagnose an isolated problem like a surge protector or something.

Welcome to the Forum. Please consider starting your own thread by posting a new Question and provide a few details. Just click this button near the first post in any thread.

Not much help bottom posting to 2 month old posts.

Sorry but there is no 1 root cause to pinpoint but welcome to the discussion. What AT&T Gateway do you have? How is your gaming device connected? And what DNS service(s) are you using?
Examples: Game console on Wi-Fi or Ethernet, BGW320 or BGW210 Gateway. DNS is the provided by DHCP?
Since this is a Customer to Customer support forum and not a formal AT&T Support path any thread may wander around due to random posts or just die out...

This post was one of 3 top results on Google while trying to research my issue, so I assume others having the same issue now will also find this 2-month old post and take some solace in knowing they aren't alone.

I am using the gateway that was provided to me by AT&T upon move-in. My gaming pc is connected to it directly via ethernet. Not sure about DNS service. I haven't messed with DNS settings at all.

Just to recap, absolutely flawless speeds/connection, until about a month ago. Speed is mostly ok, but latency always starts spiking during prime time hours (roughly 8-10 PM EST).

but latency always starts spiking

Latency, even more that bandwidth, is not a single-ended metric.  You must answer Latency to where?  If the answer is "whatever the game says," then where is the game server, and what is your route to that game server?
