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 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. ● 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. ● Verify that the encryption method (AES or TKIP) is the same for the printer as it is for the wireless access point (on networks using WPA security). ● Verify that the printer is within the range of the wireless network. For most networks, the printer must be within 30 m (100 ft) of the wireless access point (wireless router). ● Verify that obstacles do not block the wireless signal. Remove any large metal objects between the access point and the printer. Make sure poles, walls, or support columns containing metal or concrete do not separate the printer and wireless access point. ● Verify that the printer is located away from electronic devices that might interfere with the wireless signal. Many devices can interfere with the wireless signal including motors, cordless phones, security system cameras, other wireless networks, and some Bluetooth devices. ● For computers connecting to the wireless printer: - Verify that the print driver is installed on the computer. - Verify that you have selected the correct printer port. - Verify that the computer and printer connect to the same wireless network. - If your environment has multiple wireless signals and you need the printer to support dual band networks on both 2.4 GHz and 5 GHz, install the HP Jetdirect 2900nw print server accessory. - For macOS, verify that the wireless router supports Bonjour. 120 Chapter 6 Solve problems
