Access Control feature in your Tp-link router allows a user to control the devices connected to the network. A user can keep the devices in either the allowed list or in the block list. The devices allowed to access the network should be kept in the Whitelist and the devices which a user wants to be denied from accessing the network should be kept on the Blacklist. While configuring the Access Control feature through the tplinkwifi.com window, a user has to enable the Access Control feature by dragging its toggle bar to the right side. Without triggering the Access Control feature, a user couldn’t be able to utilize this feature to control the devices within the range of your network.
