[Jenne2]

I just had a new router installed yesterday and before the installation my old router was allowing the wireless connection to my printer...now I can't print wirelessly...when I go into set up on my printer it will recognize the router but keeps telling me the password in wrong and I have already confirmed today with my provider that my password is correct...they say may HP needs to do something or my printer needs to be updated with a new one as the technology may not be compatible...HELP I need my printer for work!

Welcome to the HP support community.

I understand that you are unable to connect the printer to the new wireless router, follow these steps to fix the issue.

Reset the printer's network settings to defaults

1. Touch (right arrow), touch Setup, and then touch Network. Touch Restore Network Defaults, and then select Yes. A                message appears stating that the network defaults have been restored.

2. Touch (right arrow), touch Setup, select Reports, and then select Print Network Configuration Page to print the network        configuration page and verify that the network settings have been reset.

Set up the printer using the Wireless Setup Wizard

The Wireless Setup Wizard provides an easy way to set up and manage a wireless connection to your printer from the printer control panel.

1. Set up the printer hardware. See the getting started guide or the setup poster that came with your printer.

2. On the printer control panel, touch (right arrow), touch Setup, and then touch Network.

3. Touch Wireless, touch Wireless Setup Wizard, and then touch OK.

4. Follow the display instructions to complete the setup.
