Add hardware addresses to a wireless router (MAC filtering)
MAC filtering is a security feature in which a wireless router or wireless access point is configured
with a list of hardware addresses (also called "MAC addresses") of devices that are allowed to
gain access to the network through the router.
If the router filters hardware addresses, then the printer's hardware address must be added to the
router’s list of accepted hardware addresses. If the router does not have the hardware address of
a printer attempting to access the network, the router denies the printer access to the network.
CAUTION: This method is not recommended, however, because your MAC addresses can
easily be read and falsified by unwanted users outside your network.
