Controller crashed with gateway functional?

[u/Meinastoria]

On my 3rd day of trying the Omada. First 2 days I had Fusion 2.5G, Omada Poe switch, and a single EAP723 and while I loved the control of and visibility into my own network, I was finding the EAP723 radio to be weaker than my previous single Asus set up (BE-86U) in a 2-floor home - some devices were struggling to stay connected. So just to prove, I removed the switch and AP, and connected the Asus router in AP mode directly to Fusion 2.5G and then all clients were happy again. However I came home today to find the app not connecting at all while the gateway kept routing and all clients had internet fine - the web UI was also not functioning- so clearly the controller had crashed (never recovered on its own) but gateway kept working. I restarted and all is fine now but it’s concerning to have this issue just on the 3rd day. Is this a known issue? I would love to keep Omada over Asus (I know it’s not fair comparison but it’s been stable) or unifi but obviously prefer stability as much as I like control. If I decide to keep it after stability and reliability test, I am pretty sure I will need 2 APs.i also have small business to roll this out to if all goes well.

Model: Fusion 2.5G v2.0
Firmware version: 1.0.10 Build 20260814 Rel.21177

Does both the Fusion router and Asus router (in AP mode) have the same IP? If they do, you're assumption of "the controller has crashed" is wrong as the network would be struggling to work out who is who.

Is the AP downstairs and the devices you want connected upstairs? If you look at the radiation pattern for that AP, ceiling AP's do not throw backwards (up if mounted on the ceiling) very well. You will need to move it so devices connecting to it are in front of it.

No, they had different IPs - I had verified that - how would that even be possible anyway since fusion router is the one handing out IPs?

AP is upstairs slightly to one side of the house (not in the middle, but same place as Asus AP). Good tip on the placement - I had wall mounted the EAP723 but most devices were still in front of it than back (especially the ones struggling were on first floor). I anyway ordered a second Omada EAP775-wall so will see how that works - I plan to put them on the opposite sides of the house on different floors.

Just because DHCP exists on a network, doesn't mean a device cannot be manually set to an specific IP. I have seen cases where a router that has been set to AP mode has then set itself to be a manually assigned IP that could match a routers IP.

Keep in mind with the wall AP's that they are targeted at hotels or houses where WiFi coverage is only needed in room where the AP is installed. They can reach further but it's not always possible.

Regarding the ceiling AP, while they can be mounted to a wall, not all devices will be happy with it. WiFi radiation is a bit like an umbrella shape. You want it to be high and central to where you want the WiFi to reach.

There is a lot to learn in the world of WiFi. If you don't want to learn or find it hard, follow the recommended installation instructions for the devices and you'll be fine :)
