My network was of similar complexity, until one day, I had to go away on business for a week.
Let's just say from day two onwards my wife had to use her phone as a hot-spot so she and the kids could watch TV.
I still don't quite know what went wrong, I just remember resetting everything and spending an hour setting things up again when I got back.
Nowadays I rely on a much simpler, flatter network structure. It also makes it easier to direct the wife to what to do when there are issues while I'm not home.
Exactly. However, since switching to this - everything has been 100% reliable - Internet, Wi-Fi coverage around the house, performance, etc. No issues whatsoever ...but
In my case, load shedding borked the Ubiquiti controller on the Raspberry Pi, so nothing was working. It also didn't help that the USG itself got corrupt somehow. Thankfully. I did make notes of all the customisations I did and to restore everything but first I had to setup USG as a standalone firewall just to get internet to download stuff, then used a ubiquiti backup file to restore the controller on my Windows PC as a stopgap measure , so that I could then re-do the Pi all overs again. The ubiquiti backup / restore is amazing - it's works cross platform
Anyway, this is the reason, I am now in the process of doing what I do at work - building redundancy - in this case, backup power for all my critical equipment (HOMECRIT) and switching everything to a PC/SSD. Thankfully, I ensured all my devices everything is in one place so easy to manage.
This is how far one can go down the rabbit hole ... Last week I installed a Pow R2 into the electricity feed powering all my HOMECRIT equipment so that I could see how big a UPS / battery I needed. 64w on average, so about 1.6kWh a day which is not bad for a USG, 8 port POE switch, 8 x port Gigabit switch, 2 APs, 2 x Pis, 1 x NAS, 1x Sonos, 1 x HUE, 1 x efergy and one or two other small things running 24/7
The POW R2 had a new Tasmota Firmware (8.1.0) that was available ... so it starts the upgrade process... then loses internet - why? Because it was powering everything that gave the the Internet

so it stays in minimal firmware mode (without me knowing) ... when I finally check to fix it ... the same **** happens again .. all my HOMECRIT devices are down ... felt like inception ... tells me that I need a UPS inbetween POW and HOMECRIT equpiment for this so that when the POW decides to upgrade itself, I don't lose everything.
Still must document
