So just this day I started to timeout for about 5 seconds periodically every 10 seconds
Occurs in both TF2 as well as CS:S and prolly every other game. Same goes for mumble and things like Skype.
My down/up speeds as well as ping are totally fine on speedtest.net and browsing the web doesn't seem to be affected either.
This is definetly not the place to ask since it's not related to TF2 or any programm for that matter, but I figured I might as well give it a shot here.
Edit: Upon loading twitch I noticed that streams time out at the exact same time as well, so browsing might actually be affected as well I just didn't notice it before
