Add hardware addresses to a
wireless access point (WAP)
MAC filtering is a security feature in which a wireless
access point (WAP) is configured with a list of MAC
addresses (also called “hardware addresses”) of devices
that are allowed to gain access to the network through
the WAP. If the WAP does not have the hardware
address of a device attempting to access the network,
the WAP denies the device access to the network. If the
WAP filters MAC addresses, then the printer’s MAC
address must be added to the WAP’s list of accepted
MAC addresses.
1. Press / (Configuration Page button) to print
the configuration page.
2. Open the WAP’s configuration utility, and add the
printer’s hardware address to the list of accepted
MAC addresses.
Reset network configuration settings
If the printer is still unable to communicate with the
network, reset the printer’s network settings.
1. Press and hold / (Configuration Page button),
press (Resume button) three times, and release
/ (Configuration Page button). The Power
light blinks for a few seconds. Wait till the Power
light is on.
2. Press / (Configuration Page button) to print
the configuration page and verify that the network
settings have been reset. By default, the network
name (SSID) is “hpsetup” and the communication
mode is “ad hoc”.
