My home network has 4 WAPs attached. They’re all Unifi UAP AC-Pro units, and I have a Unifi Cloud Key v3 in my server rack that controls the Wifi Network. I have 3 wireless networks: Two 5Ghz networks, one for “trusted” users and one for guests (internet only), and a 2.4Ghz network for IoT devices; each is on a separate VLAN.

The 5Ghz networks work flawlessly, but I’ve always had strange issues with the 2.4Ghz IoT network.

• At one point I had several WiFi security cameras. I could connect them, and they’d work great, but as soon as they lost power, they would refuse to connect again. I’ve since wired them all.
• The only remaining device on my 2.4Ghz network is a whole-home power monitor (IAMMETER WAM3080T). This device continually connects and disconnects. It will pass data just fine for roughly 30 seconds (or a bit less), then drop off the network, then immediately reconnect. Monitoring the UniFi software, I can see this happen in real-time.

I’ve tried locking it down to a single access point, manually setting data rate control, making sure all my firmware is up to date, all the usual stuff. I live in a somewhat remote area, so there is virtually no interference on either WiFi band, and all my access points are set to non-overlapping channels. I thought the fact that the meter is literally surrounded by metal in my electric box might be causing a problem, but when it’s connected, the connection is solid (58.5 Mbps last I checked). I could try moving the WiFi antenna inside the drywall and routing the cable through the electric box, but I seriously doubt this would help.

About a year ago, I upgraded the firmware on all my WAPs and set up VLANs at the same time. It seems to have started at this point, but it’s entirely possible this is just when I first noticed it. My suspicion is that my UniFi controller is forcing a reconnect for some reason, but I can’t find a setting anywhere to adjust this.

I’m not really sure what else to check. This is the only item left on 2.4Ghz, and I’d love to just wire it directly to my switch, but unfortunately it has no ethernet port.
