MAC address filtering

Devices (PC or PDA) connected to a wireless network and the child have a Network Card installed in a specific address: the address MAC (apart from that, a team defined by its IP address). In the router's configuration utility, you must activate the filter and enter the address MAC of each device. Thus, only those devices (known on the network by MAC address) can access the network.
No configure machinesFor thread of each machine can be connected to the network must be specified the above information. After investigating the Wireless-child, you should change the SSID to match specified for the router. Next, enter the encryption key that is specified in digital utility ocnfiguration router. Once this is done, connect the device to the router and the Internet.
