How to 'disable' FixedUpdate on clients?

[Shifty Geezer]

If I use  if(TNManager.isHosting){} in FixedUpdate, it activates a few times before the channel is properly joined. In Start I can stall using IENumerator, but how should I handle FixedUpdate? Just a Ready flag called after isJoiningChannel is ended?

if (TNManager.isJoiningChannel) return;
