Multiplayer prefab player fall through floor on instantiate

Hello Unity community, this will be my first post!

I have a problem with my multiplayer setup. When a client connects to the player-hosted server they both fall through the floor... its not a collider issue - The server-player can walk around fine untill a client-player connects; then they both fall through the ground.

Firstly let me explain my network scripts:

I have two scripts 'NET_Server.cs' and 'NET_Client.cs' There is an empty GameObject in the scene called "PlayerSpawn"

I have two separate builds of the game - one for client one for server.

When the server starts - the player who is hosting gets their prefab instantiated after the server calls the methods Network.InitializeServer() and MasterServer.RegisterHost(); all overloads are included and the init runs fine.

When a client starts the game and retrieves the server via the MasterServer host list the client connects. When the client connects OnConnectedToServer() gets called in NET_Client.cs and run the following

 print ("[CLIENT] CONNECTED TO SERVER");
 Network.Instantiate(playerPrefab,playerSpawn.position,Quaternion.identity,0);

The two overload vars are:

public Transform playerSpawn; public GameObject playerPrefab;

Now let me explain my NET_CheckOwnership script that runs in the instantiated prefab:

void Awake() {

if (!networkView.isMine) { playerObject.GetComponentInChildren().enabled = false; playerObject.GetComponentInChildren().enabled = false; playerObject.GetComponentInChildren().enabled = false; //playerObject.GetComponent().enabled = false; } else { playerObject.GetComponentInChildren().enabled = true; playerObject.GetComponentInChildren().enabled = true; playerObject.GetComponentInChildren().enabled = true; } }

please help, I've looked everywhere for someone suffering the same error with no luck. Is this problem because I am instantiating in the wrong place or at the wrong time? eek..
