When I try to play in a server, 90 % of the times it kicks me because I have a ping which is too high, and the times that I get into a server it gets kinda laggy. My computer and internet connection are fine; I play Modern Warfare 3 too and I have no problems. How can I solve this? It's very annoying.

Join low Ping Servers..

That's the problem, I do join low ping servers, but they kick me anyway.

Do u have a laptop? If u do then the game maybe assigned to the low performance graphics card, just go to ur swichable graphics setting and assign the high performance graphics card to iw4m.exe

I have a PC. Now the game enters to the servers, but even if at the start it says "100 ping", in the match I play with 250 ping. It's impossible to kill anybody with the Intervention with that internet connection

It really depends on your location, from my location i get 170ms ping to UK Servers and 250+ms to US Servers,

You could run a virus scan to make sure that there are no viruses running on your computer..

I'm from Spain, so I guess that's one of the reasons. I will scan my computer now, thx. Would it be good for the lag to reduce resolution, shadows and other video settings?

Reducing you resolution and Disabling Shadows,Depth of Field and Specular Maps will definitely increase your Frames Per Second, thus you will have a better gameplay and it will be much smoother,

I have disabled those video settings and now I play much better. Thanks
