You can check the list of connected computers and mobile devices with Mac addresses and the assigned IP address list.
Go to IP > DHCP Server. Select the Leases tab.
Check the Active host option for the computer or mobile name. View the MAC and IP address details for the specific user you want to block.
Note the IP address of the mobile or computer you want to restrict Internet access.
