I have been using an OBI202 for many years now with no problems, but recently the unit randomly disconnects and then immediately reconnects to my router. It is connected via an ethernet cable so it's not a WiFi issue and I have the latest firmware installed. I have also tried using a reserved IP address for the OBI device and still have the issue. The problem is not constant, but it occurs several times a day, every day. Has anyone experienced this problem or have any ideas on how to resolve it?
