John, thank you very much for the feedback! Since there were no changes for the Status page in the last two updates, the page should not be broken (in theory). You are the first one who reported such problems, so please let us know a bit about your network. I.e., how you connect to the Internet and how the devices are connected to the router.
In the meanwhile, you can add new devices in the Network Settings page: in the “Hostnames and Static Leases” section, click the Add button. In the popup dialog, connected devices should appear under the Name dropdown. You can either identify the device by name or IP address.
You can either use tools provided by the OS to identify the IP address of a device (for example on Windows, open a command line window and enter “ipconfig”), or open a browser on the device and enter http://192.168.10.1/myip.html.
Once you identified the device, save the name by clicking OK in the popup dialog. Then click Save at the bottom of the Network Settings page. After that, you can manage the device in the parental control page.
