             {

                 Quaternion spawnRotation = Quaternion.identity;
                 Instantiate (mobPrefabs, spawnPosition, spawnRotation);
                 yield return new WaitForSeconds (spawnWait);
                 mobSpawned++;
 
                 if (mobSpawned <= 2)

Hello.

If is true theat code does not execute that while, is because never reach it. Is not problem of the "while".

yield break; exits the Coroutine. So on third spawned mob, you exit from coroutine. I highly suggest to spend some time learning how to debug code through breakpoints and step by step execution. (Or for someone less experienced, placing a lot of Debug.Log("Message"); to check how the code is running)

Thanks you. I solved the problem. I added an Void Update, if mobSpawned = 0, start timer, if timer = 0 start the coroutine SpawnWaves
