Some players show they are on the other team when they are really your own team

I have been on the other side of this.  Match will be playing fine, you die, then reload.  You will first notice that you will be kind of laggy, you cant crouch, reload or nothing, your friends will also not be able to see you.  Then you get killed by an enemy, which then you can not be revived or kill your self to reload.  Every time this has happened I have had to restart the game.
