Is the camera not seen from Home -> My devices or from Home -> Advanced Settings -> My Network -> My Devices?
When you click on the 'My devices' button under the advanced settings the Hub sends an ARP for every address i.e., 192.168.1.0 - 192.168.1.254 to populate the list, so it's odd that it's not picking it up.
If you go into the Advanced Settings -> Technical Log -> Event Log and filter on 'Wifi' do you see the MAC address of the camera in the list?
Does the camera make any outgoing connections that would have to go via the hub i.e., to the Internet or are you only accessing the camera locally? If it doesn't and there's a way to make it send some traffic to the Internet, try that and see if it appears. Perhaps the hub is only showing devices that send traffic through the hub to the Internet.
