In the last few days, I've started got get very frequent ping spikes when gaming (mainly CS:GO and Tf2). Pingtest.net gives me around 40-50 with no packet loss, but when I start gaming it jumps all over the place, usually sitting around 150-200, which is pretty unplayable. Is there any reason why this would start acting up all of a sudden? It was fine until now, in fact the ping was usually 30 across the board. Maybe I could change some router settings, but I'm pretty clueless about that to be honest. Any suggestions would be much appreciated!
