We currently have 1 GIG internet with Frontier (Modem model NVG468MQ), recently I will begin to lag whenever my dad starts using his PC. I have check task manager and confirmed that it's not CPU, GPU, or lack of storage. In the task manager ethernet setting I will see my send & receive constantly hit 0 than not go over 100 KBPs. I have watched tutorials on how to set up your routers Qos, but my router settings do not look like others. Where others have more options, it seems my Qos would be for phone lines? I feel like 1 GIG of internet should be enough, we have 2 PC's hard lined to the one router and a different router for all wireless. Any ideas of how to fix, or a different way to set up a fix.
