So ubiquiti can't be trusted. What are the suggestions for running a ssries if home and small office networks in rented buildings (no cabling?). A UDM + nano ap / flex HD as wireless bridges & mesh wifi gave VLANS, performance monitoring, and an ease of use that let even a junior UI dev implement use it easily and correctlywhile complying with all lease req's.

With the world of work at home exploding there seems to be a big missing link here.

I'm sitting with a big list of q's that I'm not sure I have a decent amount of time to answer. Does switching to pfsense/openwrt/something open source work with mesh? With ease of set up? Do enterprise brands offer anything worthwhile here? Do I have to regress to letting machines connect to unsecured networks?
