This problem is not directly related to LoL, but because of it I can't play LoL smoothly.
A week ago something weird started happening to my connection. It overall feels a bit slower, but the main problem is that I get huge lag spikes every 10-15 minutes. In LoL (or any other online game), I stop for some 5 seconds, not being able to do anything, while I watch others crush my face in. I can normally watch streams at 1080p, but since the problems started I can barely watch them in 360p, during the spikes even 240p dies.
Speedtest and other sites like that still show the same speed I had before the problems.
I did send a report to my ISP, waiting for the answer atm. Hoping someone here can possibly shed some light towards fixing my problem.
Thanks in advance
