So randomly today I get on my desktop (connected with ethernet cable to netgear r6400 router connected to my modem) and on numerous games I'd get random packet loss and ping issues causing me to even disconnect. I called my ISP and there are no issues on their end. I also did a factory reset on my modem after a firmware update failed to solve the problem. Internet speeds seem fine it's just random spikes. Any ideas? It's been fine for 4-5 years till today.
