My internet has not been stable for the last year. It's tiny lag but nevertheless still lag, my ping in QL and CPMA ranging from about 8-40 ping (on a server location near me, not 20 different servers). I've had 3 different ISPs and always had the same problem. I'm currently using a connection with 60mbps download and a 6mpbs upload and it's still lagging.

I tried turning off auto-protect from my virus scanner (basically it doesn't do anything then), I've turned off all other programs not in use (like MSN Messenger and Steam) and had nothing unnecessary running visibly. My in-game settings are also fine. My FPS is always stable at 125. What can I do to make it stable?

This is a screenshot from my Lag-O-Meter:

edit: Just now on a swedish server in QL(I am from the Netherlands) I had a ping ranging from 34-64 on the scoreboard and worse in my lag-o-meter with very big spikes.
Nothing is updating but it feels like someone is torrenting with an upload of 50-80 kb/s on my PC, but that's impossible since i'm plugged directly in to the modem.

edit2: Apparently it also crashes my internet around 10 times a day at first I thought this was cause of my old ISP apparently its not.
