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. 11 Add hardware addresses to a wireless router
