If you still cannot use the HP device over the network or if you have to periodically perform
this step in order to use your device over the network, your firewall might be interfering.

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 device’s MAC
address must be added to the WAP’s list of accepted MAC addresses.
