I've been having a problem recently where I get very high packet loss in some servers/applications but not others at peak times (7pm onward) everyday.
In mumble and teamspeak, I get around 40% or even higher packet loss. I also get very high loss in CS:GO matchmaking servers as well as faceit and ESEA (Around 40% as well). The surprising thing is I get no packet loss in CS:GO FFA dm servers or any community servers, neither do I in TF2 game servers.
I am on university halls internet which is obviously not ideal but the nature of the problem where I only get loss on some servers makes me feel like there could be some fix. I initially thought it could be some sort of issue with the university's firewall blocking or slowing some ports but the CS:GO servers all run on around the same port and I only get loss on the competitive servers.
I am connected by ethernet so that isn't the problem. Thanks so much to anyone that can help.
EDIT: forgot to say, ping is excellent in all cases, it is just packet loss.
