Smart Life Device Keeps Disconnecting Daily

[techdiver]

Hi,

I have an RT-AC86U as my main mode and 3 other nodes connected in mesh. I recently bought some bulbs that connect using the Smart Life app. Setting up was fine and everything worked correctly. What I have noticed that every morning they have been disconnected in both the app and Alexa cannot see them any more either.

I had previously had similar issues with smart plugs but it was more infrequent and a power cycle of the device would solve the issue. The difference here is this smart bulb will never reconnected even after the power being turned off to it.

The only way to fix it is to bounce the router (or as I found a more elegant way of just disabling/enabling the 2.4Ghz band). So it seems to me the issue is on the router side.

I have checked the logs and the issues start happening when I see this in the logs:

We then get this repeated in the logs every minute until I either bounce the router or the wifi band:

Once I bounce the wifi or router those log entries stop and the device is connected fine.

I have tried many troubleshooting steps that I have found online. I set a mac reservation for the device, disabled (Enable WMM APSD), but once again today the same issue that required the wifi to be bounced.

I did notice in the logs before the entry above where it failed to reconnect that there were a few successful cycles of it connecting:

Is there anything else to try as I've an out of ideas at this point.

An update on this. I had read elsewhere that adding these devices to the guest wifi network can help stop issues. I reluctantly did so and it actually seems to have worked. I added the device to the 2.4Ghz guest network and now everything is stable 2 days later.
