Although I have 7 Wireless Clients and 8 Wired Clients connected, all Client Lists are empty. This happened suddenly after changing some settings. I used to have the lists populated with all clients both in front page of "Basic" view and in "Advance" view under "Network", "LAN Settings". Now all lists are empty. The router seems to work perfectly otherwise, but it is extremely annoying that list are empty, as there is no other way to identify connected clients than looking at the lists.

Here is a screenshot of the "Basic" view, where the router correctly announces that there are 7 Wireless Clients and 8 Wired Clients connected, but it just doesn't populate the list when clicking the icons, as it used to do.

Here is a screenshot from "Advance" view under "Network", "LAN Settings", showing the empty list:

In other posts about empty client lists it has been proposed to switch off and on DHCP. This doesn't work for me!

Rebooting the router doesn't bring the Client Lists back.

I have also restored a saved configuration from file. That configuration was saved to file at a time where Client Lists worked fine. Restoring that configuration didn't bring back the Client Lists either!
