Sonoff DW2 Wifi always keep disconnect

My DW2 often disconnects from the wifi connection. When disconnected, reconnect and the next day still disconnected again. How to solve it? The connection from router not too far.

How long have you been using this smart sensor? You can bring this to the manufacturer or seller’s attention. It seems a hardware connection issue.

HI All

Same issue here.

5 devices working perfectly until yesterday. now all offline and cant get them to reconnect.

It might be that your WiFi is limited to a certain number of devices. Like my ISP is set to 5 devices per user account .
Buy and plug a non SIM card WiFi router on your ISP router on the ethernet port then connect all your devices on a new WiFi router .

Since a few days ago I’m facing the same problem…

I have some sensors that show the same behaviour. Mine are either WiFi low power sensors or Zigbee ultra low power sensors. The Zigbee sensors with that behaviour have generally (2032) batteries. They tend to wake a few times a day to transmit and immediately after return to sleep.

Have you managed to get the DW2 Wifi working yet?
I haven’t been able to, for several months.
Is the solution to start throwing them in the trash?

Your DW2 still not working properly?
There must be some specific reason for this… Mine is currently working and I don’t think it’s losing connection or I’m not noticing it.

Have you tried ping every now and then? Mine gives a response to a regular ping, of course the times are abstract, on average 3-6 seconds,… yes seconds :slight_smile:
The problem is that after it receives some packets, it seems to hang. It stops responding and probably becomes dead on the cloud side, it certainly doesn’t try to reconnect to wifi if its connection drops.

DW2 constantly wants to go into some low consumption state and when it enters it, it only wakes it up when it is opened. Although in my case it doesn’t lose WiFi because of it.
But it has a different tendency - if for some reason there is no Wi-Fi for some time and after a certain period of reconnection attempts, it goes into silent mode and only opening it will wake it up and try to connect again.

Maybe try to isolate it from the rest of the network, use a separate SSID or hide it behind a firewall. Also look at what is happening on the network and what packets are flying to/from it.

As a CUBE dev, don’t you have any internal contacts with the company who could somehow raise the issue?
