firmware. For instructions on how to update the printer firmware, go to http://support.hp.com , search for your

Wireless connectivity checklist
Use the checklist to help resolve wireless connection issues.
● 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.
