If you are able to use the HP device over the network, your network setup was
successful.
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.
If this still does not work, there might be a problem with your network configuration or
router. Contact the person who set up your network or the router manufacturer for help.
