Hello!

Not so long ago I started having horrendous lag spikes. All day, every game. Basically, WoT became unplayable and today it started pissing me off. Right now I'm connected via wifi to router with 9db antenna (router is in bedroom and i'm in the next room, about 2 meters from it). I've played CS:GO (without problems) and The Crew (few disconnects, once a day). Browsers work on full speed. I've added speedtest, pingtest, ping plotter log and the replay of one of the battles with this problem.

Here is the picture of the log:


Please help me interpret the graph: what is the main problem? My network or something else?
