Solved by my Self
I don't know why this is happening. but when I'm going to play with someone in a few seconds it starts lag lagging and my friend and I start lagging. It doesn't happen when I'm playing alone. It is unplayable with those lags that lock everything.
(For those who do not know and that lag that everything is flying and the map does not load usually giving dc after a few seconds)
