Hi, it is possible that the Wi-Fi signal in your home is interfering with the Zigbee signal. Changing the Zigbee channel may help, and we also recommend keeping some distance between your Wi-Fi access point (or router) and the bridge.
We haven’t released any recent firmware updates, so under normal circumstances, this issue is unlikely to have been caused by an OTA update.
May I ask whether the bridge is disconnecting from your Wi-Fi network, or are all Zigbee devices disconnecting from the bridge?
