 Check the router band setting: Many routers operate in both 2.4 GHz and 5.0 GHz frequency
bands, but not all HP printers support both bands. Make sure the 2.4 GHz router band is turned
on and broadcasting. If the router broadcasts separate network names (SSIDs) for each band,
connect the printer to the 2.4 GHz band SSID.
 Check your firewall software: Your firewall software might prevent the printer from accessing
the computer. Accept or allow any firewall messages that display during the printer software
download and installation. You can also configure the software to allow HP downloads and
installations.
 Check for obstructions between the printer and the router: Remove any metal objects between
the printer, the computer, and the access point (router). Objects such as refrigerators or metal
bookcases can interfere with wireless signals.
 Check for other devices that emit radio and wireless signals: Move any devices that emit radio
signals, such as microwaves and cordless telephones, farther away from the printer.
 Set the IP address on the printer: Your printer can bypass automatic IP address assignment by
DHCP and use any valid IP address you choose. Use the control panel menu to type an IP address
that is valid for use on your local area network.
Wired (Ethernet) connection
Try these tips and procedures to troubleshoot and avoid wired network connectivity issues.
 Restart the printer and the computer: Restarting the computer and the printer can clear error
conditions.
 Confirm the network connection: Confirm that your printer is connected to the wired network by
checking the cable and the lights on the printer’s Ethernet port. The green link light should be
steady, and the orange activity light should blink when the cable is connected.
 Check the cable: Examine the Ethernet cable attached to the rear of the printer to make sure that
it is not a phone cable (Ethernet cables and phone cables look similar but are different sizes).
 Ethernet Cable
 Phone Cable
 Reconnect the cable: Disconnect, and then reconnect the Ethernet cable to the rear of the
printer, and then plug the cable into another valid port on the router.
 Use a different cable: Connect a different Ethernet cable.
