Synching Problem of players in multiplayer 2D game.

I want to make 2dGame which is something similar to “funrun”,I have started it and use Photon plugins for multiplayer, The all the Players are connected in network,but their position while running is not properly synched in all networked devices.So please tell me any reference for this .
And also give me some reference links for tutorials for MultiPlayer which helps me to learn from scratch.

Because of lot of data to be send over network, it causes problem, so it is better to send minimum data, and sync position in fixedupdate if using physics.

If have better solution , then just share it…

Cheers…
