I currently have cisco 2203 modem and D-Link DIR-501 Wi-fi router. When I installed all this network devices the internet connection was ok. What ever I do on my laptop it wouldn't affect my PC. But after all problems my ISP had ( some1 was stealing their optic cables from the 2m below ground, probably some others jealous ISP in my country ) now whenever I play some youtube or stuff on laptop my ping goes up by 10 and comes down. That is irritating me because I play FPS games where is ping most important stuff, along with fps. I reseted my router to the factory settings but same stuff occurs, I have also restarted my main cisco modem and it didn't fix this issue. So is there any tweak or something where I can fix this. And also can I somehow fix the youtube bug, where when I play youtube videos it affects my ping ingame, like I put some playlist and whenever Youtube switches song my ping goes up from 40 to 150-220 for a couple of seconds (untill it loads small amount of video) and comes back down to 40. This is annoying when I play League of Legends. Like I noticed every LoL livestreamer plays youtube and streams, but whenever youtube switches song their ping is still same
