RPC setName() not working correctly

I have a function called RPC setName()

basically as soon as a player spawns I call

 gameObject.GetComponent(NetworkView).RPC("setName",RPCMode.OthersBuffered,PlayerPrefs.GetString("stringyName"));

What happens is that when there are two players connected everything is fine. I see other players name, other player sees my name when aiming at me. Once a 3rd players joins everything goes to hell and all our names are messed up for the 3rd player.

here is the function itself:

 @RPC
 function setName(temp:String){
 
 myName=temp;
 
 }
