Lag problems on Dota caused by my router
Hi guys. I've been having some heavy lag problems since I started playing dota 2. Recently I started doing some testings and I concluded these problems are caused by the router I use (My internet is not wireless). When using a direct conection Modem to PC I have no lag at all.

Now, I tried deactivating the router's firewall and I got the same results, still an unbearable lag.

Model is: TL-WR641G / TL-WE642G. Could you please provide me some help to solve this problem? I need to use this router, it's really hard to switch to a direct conection every time I want to play

PD: When I say LAG I mean I can see everything frozen, moving but doing nothing, then 3-5 seconds later I'm dead and have no idea of what happened

Port Forwarding within your router:

UDP 27000 to 27015 inclusive (Game client traffic)
UDP 27015 to 27030 inclusive (Typically Matchmaking and HLTV)
TCP 27014 to 27050 inclusive (Steam downloads)
UDP 4380
