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.
