Fixing connectivity issues

You may have picked the wrong network or typed in your network name (SSID) incorrectly

Check these settings to ensure that they are correct.

You may have typed in your WEP key or your WPA encryption key incorrectly.

•If you are using encryption on your network, you’ll need to enter a key. These are case- sensitive so be sure that it has been entered correctly.

• If the network name (SSID) or the WEP/WPA key are not found automatically during installation, and you don’t already know them, you can download the Network Diagnostic Utility, which can help you locate them.

•The Network Diagnostic Utility runs on computers with Windows XP SP3, Vista, or Windows 7 OS. The computer should also be wirelessly connected to your network. To download the Network Diagnostic Utility, go to: www.hp.com/go/wirelessprinting.

You may have a router problem.

Try restarting both the printer and the router by turning off the power on each. Then, turn them on again.

Your computer may not be connected to your network.

Make sure that the computer is connect to the same network to which the HP Photosmart is connected.

Your computer may be connected to a Virtual Private Network (VPN)

Temporarily disconnect from the VPN before proceeding with the installation. Being connected to a VPN is like being on a different network. You will need to disconnect from the VPN to access the printer over the home network.

Security software may be blocking communication.

Security software (firewall, anti-virus, anti-spyware) installed on your computer may be blocking communication between the printer and the computer. An HP diagnostic utility runs automatically during installation and can provide messages about what might be blocked by a firewall. Try temporarily disconnecting your firewall, anti-virus, or anti-spyware applications to see if you can finish the installation successfully. You should re-enable the security applications after installation is complete.

Setup your firewall software to allow communication over UDP port 427 (Windows).
