I’ve been having some Internet latency issues that mainly affect me when I play online games.
To try and figure out when and what is causing it, I’ve created a small latency monitor which monitors the latency by pinging google.com. It does this over a wired connection.
Today, when my wife came home, I immediately saw an increase in latency. I asked her to turn airplane mode on on her phone and the latency went back to normal. So I’m pretty sure that it’s her phone causing it.
I’ve tried looking at the traffic stats in our router. It’s a TP-link Archer C3200. But I haven’t been able to see any excessive traffic from her phone.
It’s also not just the phone downloading a minor amount of data when it connects to the wifi. It goes on for hours.
How can I further troubleshoot this? And what can be causing it? As I’ve said, the latency goes up on a fully wired connection, so I don’t think it’s related to wifi as such.
