My guess would be yes. Most of those released 2015-2016. We've since seen their 3rd gen products released around 2018 with the HD products, and now the UAP6 devices are starting to trickle out. Doesn't really make sense to keep promoting the older stuff.
OK late to the thread. We use a cheap travel router for this purpose. GL.iNET GL-MT300N think we paid $25 for it. Supports up to 4 SSID's and can do VLAN's though we only use 1. We can actual do wifi to wifi bridging with it. We use it for these wifi Sapling clocks that need to connect to a pre-provided WPA2-PSK ssid for initial setup.
This is the newest version: https://store.gl-inet.com/collections/travel-routers/products/gl-mt300n-v2-mini-smart-router
Can get these on Amazon now for $25
What does it cost to have fiber terminated? $150/hr? Since this is in the mountains, I'm guessing the nearest city is 1.5 hours away, so drive time on top of that. I'm just guessing at the labor since I haven't ever had it quoted.
Right, so if oyu are confident that premade will pull in quantiy, then by all means go with it.
The good thing about fiber, is that it doesn't matter if you coil up the left over.
Controlled migrations have lots of tools and options.
But a downed controller has pretty much no option except to default the APs and readopt.
You will not even be able to SSH into the APs if you cannot log into the controller and get the device admin password for the site.
@JaredBusch is right. If you lost the controller it is a reset process. I recently went through something similar, however, it was the fact that our ISP at a location I manage decided to change out there cable modem and in doing so changed them from a static IP to a dynamic IP. Which is fine and easier for me but they didn't tell the client that they might have to reconfigure their equipment and didn't even bother to make sure they had internet. Switch cable modem and left. Client calls me and I get there and well the Ubiquiti Secure Gateway wasn't working because it was set to use a static IP on the WAN side. I was mad. So I had to reset the Ubiquiti Secure Gateway. Now here is the kicker, it would show up in my controller once I set the inform address but for some reason at least on the smaller USG's is that you had to ssh into them and set the inform address. Click on adopt in the controller and then while it says adopting in the controller run the inform command in ssh again. If you didn't do that it would be adopted but say disconnected. It was a long night until I found those instructions. Grrrr.
We've been able to Default the remaining APs and they are adopted. We have one that is being stubborn, while it 'pings' it's not reachable. Suspect an issue with the AP itself. One just lost the heartbeat, but, it was found and adopted.
All in all, four of the six are running and good to go. lot better than where we started.
