It's my first post on this forum so let me introduce myself for first. I'm Alan, 16 y.o from Poland. From about 4 days im having ping spikes and lags in generall in-game (League of Legends) so I really can't play. In game's producent article about preventing lags they've said to do an internet analisys. I did it:
http://n2.netalyzr.icsi.berkeley.edu/su ... -4f23-8f36
I found there, that my "Network buffer measurements : Uplink: 1100ms, Downlink 300ms"
Also: "We estimate your uplink as having 1100 ms of buffering. This is quite high, and you may experience substantial disruption to your network performance when performing interactive tasks such as web-surfing while simultaneously conducting large uploads. With such a buffer, real-time applications such as games or audio chat can work quite poorly when conducting large uploads at the same time."
This is really unplayable and I don't really now what to do with it. There is also a "SpeedGuide Analyzer" results:

I've read that I should setup my QOS but I really dont know what is this. My router is TPLINK TL-WR740N.
Any kind of help will be really appreciated. Have a nice day

EDIT: http://www.pingtest.net/result/128096176.png
Before I got lagged with those, I've always had 40-45 ping (in game, nowadays it's about 70-200) , 0 packet loss and about 0 jitter
On this page my ping was like 5-10 http://www.speedtest.net/my-result/4551611617
