KAG [Solved] I can't connect to any server

I cant join to any server. When I try to enter one it say connecting to server at top after some loading. But it never connects. Then it says disconnected from server. Singleplayer works fine.

I disabled all of the firewalls and stuff but nothing changed
I've bought this game from sumer sales. When I first entered it, I used my old free KAG account to link it with Steam. Maybe that's the problem because free account cant join multiplayer section of game.
also sorry about my weirdo English :3

 

Here it is

Ok I finally figured out the problem but I dont have any idea how to fix it.
I use a powerlink adaptor to connect to my modem instead of wireless because it is very far awar from PC. I can use it to surf internet but it is not even close to being enough to play and multiplayer games.
Anyways I tried wireless connecting instead of powerlink and I connected any server easily. It is laggy but atleast I foun the problem
This powerlink connecting is full of issuses. I lost my connection very often and only way to reconnect is reseting the PC. Sometimes it happens randomly. But in certain sites I lost my connecting 100%. Which is just extremly annoying.
So yeah the issue is my annoying powerlink connection...
