Add hardware addresses to a wireless router

MAC filtering is a security feature in which a wireless

router is configured with a list of MAC addresses (also

called “hardware addresses“) of devices that are

allowed to gain access to the network.

If the router does not have the hardware address of a

device attempting to access the network, the router

denies the device access to the network:

1. Locate the MAC address for the HP Officejet/

Officejet Pro device. This address is printed on the

serial number label (typically located on the back of

the HP device), and this address is also printed on

the Network Configuration Page. For more

information about printing the Network

Configuration Page, see “Make sure the HP

Officejet/Officejet Pro device is on the network” on

page 7.

2. Open the router’s configuration utility, and add the

device’s wireless hardware address to the list of

accepted MAC addresses.
