NOTE: To determine whether HP NFC and Wi-Fi Direct printing are enabled on your printer, print a configuration page from the printer control panel. NOTE: If you have been experiencing intermittent loss of network connectivity, first update the printer firmware. For instructions on how to update the printer firmware, go to http://support.hp.com, search for your printer, and then search on "update the firmware." Wireless connectivity checklist ● For printers that do not support simultaneous wired and wireless connections, verify that the network cable is not connected. ● Verify that the printer and the wireless router are turned on and have power. Also make sure that the wireless radio in the printer is turned on. (The wireless network indicator is solid when the printer is connected to a wireless network, and blinking when it is searching for a wireless network.) ● Verify that the service set identifier (SSID) is correct: - For a wireless connection to your network, confirm that your mobile device is connecting to the correct router/access point. - For a Wi-Fi Direct connection, print a configuration page to determine the printer's SSID. If you are not sure that the SSID is correct, run the wireless setup again. ● With secured networks, verify that the security information is correct. If the security information is incorrect, run the wireless setup again. ● If the wireless network is working correctly, try accessing other computers on the wireless network. If the network has Internet access, try connecting to the Internet over a wireless connection. 218 Chapter 9 Solve problems ENWW
