I'm enjoying this discussion and trying to learn. I looked at the Extreme Networks options and they are pricey and they seem mostly designed for wired input to each wireless access point. Since my home was built in the 90s, it isn't wired for internet.
I do work at a fortune 500 company with very high end equipment such as this in the wifi system, and our wifi at work is consistently less reliable than mine at home. So I'm scratching my head.
