I will explain the whole situation, but will have a TL;DR at the bottom I guess. I play this game called League of Legends on a regular basis. About 2 days ago, I started noticing that my ping was rising upwards of 500-1200 at peak, (usually stable 90 ping) and this was odd because I haven't had an issue with lag in months. Right as I notice the lag, I try to close any programs that might be taking bandwidth or anything else, nothing worked. I went into processes, ended any and every process that I could without crashing the system. Nothing helped. After that, I decided to test it with another game, Counter Strike: Source. Same issue, high ping. I did a speedtest and it was normal, my average ~20-30 ping, 25mb down, ~1 up, so I did a Malwarebytes full scan overnight. A bunch of things came up, mostly PUP's, but I removed them all, and it did nothing, and then today I go to look and my download speed is down all the way to 2mb, ping around 30 and upload around .8. I made sure that nobody else in the house was downloading anything every day, and nobody was. I used various programs to monitor if certain programs were using bandwidth or anyone else in the house was, and nothing. I have no idea where the source of this extreme lag is, and I am frustrated at the fact that after all of the searching I can't find any solution. Please, any suggestions as to what the issue is? I may have tried other things that I forgot to type here, just ask me and I will let you know, or do the suggested method that you state.
TL;DR Random extreme lag occurs, tried many things to fix, nothing works
Edit: an hour later, I speedtest again and I get 18mb down but 261 ping and .8 mb upload. So confused.
Editedit: minute after previous edit, I get 50 ping, 17mb down, and .8 upload, hmmm.
I don't understand how I can stream 1080p twitch.tv channels but multiple games get 200-1200 ping...
