My internet modem has the login IP address 192.168.0.1 and is setup as a DHCP server, providing IP  addresses 192.168.0.x. The TP-Link login IP address is 192.168.68.1 and is also setup as a DHCP server, providing IP addresses 192.168.68.1xx. There are occasions, when a client has a wired, rather than a wireless connection type, and I would like to be able to disconnect it from the connected clients list. How can this be achieved?
