In this video I go over some things I learned running a fixed wireless ISP.
Hopefully you can learn something from this. Even if you're not in the industry.

I would apreciate more feedback below in the comments. I can make a few more follow up videos if you guys want.

If you guys don't like it this will be the last one.

I left out boring stuff like network segmentation because its so obvious that you should never have more than 50 clients per broadcast domain or else you will have lots of issues especially if you do pppoe.
