Enabling MAC address filtering improves security as only computers known to the network are allowed to join and any computers trying to join when their MAC address is not recognised are blocked.
MAC address filter is a pretty secure way of rudimentary network security. Enabling it makes the network available only to know devices. However, this leaves it vulnerable to MAC address spoofing.
MAC filtering takes network security to the next level by only granting access to specific network cards.A MAC (media access control) address is a unique identifier for a network card; no two cards have the same MAC address, so it functions like a fingerprint - even a wireless card and an Ethernet card built-in to the same laptop won't have the same MAC address. Therefore, MAC address filtering adds security by only allowing network cards with the right "fingerprint" to access the network.However, it should be noted that MAC address filtering is not a strong form of security. MAC addresses are extremely easy to "spoof" - that is, it's easy to fake the address of a legitimate network card. If an attacker is able to identify the MAC address of a permitted network card, they can masquerade as the legit card. Therefore, MAC address filtering is not a replacement for using encryption. MAC address filtering can help security if used in an environment running WPA.
MAC filtering
Turn on MAC address filtering, and turn encryption on for all connections. And limit the address pool aswell.
Unauthorized access to a wireless network can be prevented by using strong encryption methods like WPA2, setting up a strong password, enabling network security features like MAC address filtering, and regularly updating the router's firmware.
You will need to access your wireless router's configuration. There should be a section for Wireless security, then there should be a section for MAC filter. Can't give specifics as you didn't mention the brand.

Mac filtering is most efficient with wired networks. It is not very efficient with wireless networks, because hackers can very easily eavesdrop on you.

i want settings mac address my router...only internet access by mac
MAC addresses are easily spoofed.
