Get online support
As I previously tried I couldn't find any workaround to see the connected devices in my Sagemcom 5866T 5G modem due to the well-known but not-yet-fixed firmware issues. I see some people have reported that they can see the connected devices from time to time. So I thought of sharing other users' experiences to find the auspicious time to log in to the modem so that we can see the connected devices.
