What are some time tested passive income streams?
I owned and managed a few residential properties.  At one time the net cash flow was on the order of $1000 per month.  But it was work.  Lots of work.  I was managing about 7 units. This does not count the gains in capital appreciation which were significant.   Using a management company would have put the cash flow at 0 or in the negative and would have lowered the quality of management IMO.   Nothing comes for free...
