Speed Cheat im beeing kicked!!!(NOT CHEATING)

[Doteren]

Im new to this game, i really enjoy it but i have an annoying problem.

I keep getting kicked/banned from online games because of speed cheating?
I have no other apps running while playing the game and im sitting on an 100mbit line.
I have stopped useing wireless and play with lan cable in my modem (someone told me that would help)

I really dont cheat and i need help to solve this problem.

Im really sorry about my poor english and i hope you understand me.
