Solution to wifi devices becoming unavailable when using Unifi network and access points

Third party integrations

Hi all
Sharing a solution to a problem I was facing but didn’t realise it.

I began noticing lag or failure for some of my lights to turn on or off based on automations. I have a mix of wifi and ZigBee devices but the impacted lights were primarily wifi. Looking at my logs I noticed a repeating and widespread behaviour for my WiFi devices to constantly flick between available and unavailable. Checking the logs on my Unifi Dream Router revealed that my devices were dropping off the network and reconnecting.

I did some quick Copilot querying and Google searches and they pointed me to doing the following:

  1. Block Tuya devices from the internet
  2. Disable cloud integration from LocalTuya integration
  3. Disable Fast Roaming on my Unifi router advanced manual wifi settings

I did all 3 without luck.
Last thing I tried was to disable BSS transition. Fingers crossed but I think that has fixed things!

I’ve applied these settings to my 2.4ghz SSID that handles my IoT devices. You can probably leave fast roaming and BSS transition on for your main 5ghz device network e.g. phones, tablets, PCs if needed.

I’ll report back if I continue to see issues.

Thanks for posting that. I’ve gone ahead & applied those suggestions to my Unifi IOT VLAN / SSID (except Tuya; no need here).

In addition, I noticed another setting that could be enabled for that network in Unifi: “Enhanced IOT Connectivity”, & I enabled that one also. Description says “Limits the network to 2.4 GHz only with special compatibility settings”.

I’m interested to see if any of that helps.
