For about the last week I've been getting pretty bad lag spikes and I have no idea what is causing it so I'm wondering if anyone might have some ideas to try and fix the problem.
Basically what happens is at random times (generally 2-3 times a minute) I will seemingly just lag out. If I'm playing WoW all my abilities will start queuing up, if I'm watching a steam it will pause and start buffering or if I'm playing Counter Strike I will rubber band every now and then.
Speedtest shows no problems. I'm directly connected to the router, no WiFi. I have tried turning WiFi off thinking someone else might be downloading and today I tried turning off and unplugging my router + computer for about an hour and cleaned all the dust out thinking it could be a hardware issue but still nothing helps.
Probably something to call your ISP about, if it's only been happening for the past week. See if they've made any changes to anything recently, and if they can get someone out there if needed.
