Wifi dropping out for 2.4Ghz devices overnight

[Yellow4life]

Smart devices are dropping out each night, these all seem to be on the 2.4Ghz network. I have the hub running in modem mode connected to a Tenda MW12 mesh system. This was put in place in the hope that the issue would resolve since the problem occured when using the Virgin Hub 3 in standalone router mode.

The smart lights will work throughout the day/after sunset but by the morning they appear offline meaning that the smart sensors (smartthings cannot reach them) to turn them on. If I switch the devices off/on then they come back online until the next day.

I have tried the usual hub reboot, hub reset. I even bought a new lighting system (Wiz) to see if this would resolve it.

Any ideas please?

The Hub's log has three entries dated  01/01/1970  which suggest the Hub3 has been rebooted perhaps even powered off.

Look at the date / time just after each 1970 entry to see when that happened.

Thanks for replying. I have restart the Hub a few times in the last couple of days - so there is nothing obvious here that could show what the problem is?

Thanks for your post on our Community Forums, and a very warm welcome to you @Yellow4life.

Sorry to hear of issues you've been experiencing with the connection, how have things been performing since your most recent post?

Have you set up a broadband quality monitor on the connection to keep tabs on this?

Kindest regards,

David_Bn

Hello, thanks for the welcome. Sadly there has not been any progress really. The Yeelight and Wiz connected systems both seem to disconnect each night. They are definitely both on the 2.4 network

Using 2 quite different WiFi systems the devices become disconnected and remain disconnected.

If a mobile phone did that we would soon conclude the phone was faulty.

Hey Yellowlife, thanks for your posts and updates on our help forums and this thread.

A warm welcome to our community too!

We're sorry to hear of the connection issues being repeated, we'd love to best help with this.

Based on our latest checks there doesn't seem to be an issue with our network affecting your service, at the minute.

Can you please tell us how things look with your connection since you last posted here on Thursday and have you had any improvements?

Also, could you please let us know if the issue happens only on wireless or over wired connections too and have you noticed this with different devices as well?

Lastly, when did you last reboot the hub and has this helped at all restoring the connection problems, if so?

Let us know how you get on and if you need more help, here to assist further.
