With the help of the Access Control List, a user can keep control of the number of devices that are allowed to connect to the network and the devices that are kept away from the network. The access control list is maintained and controlled through the linksyssmartwifi.com window of a Linksys Router. If a user is allowing more than a suitable number of devices to connect to the network, then he may encounter a weak signal issue that must be resolved to get the actual performance of your router. A user has to select the “Specify an Access Rule” check box to allow the “Allow and Block” button to control the list of devices that are within the range of your network.
