Hi @RangerBM,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you are to set up your HP Officejet 4620 wirelessly after changing your modem on macOS X 10.10 Yosemite, follow these steps:
 

Connect Your Printer to Your New Network:

• Turn on the Printer: Ensure your HP Officejet 4620 is turned on.
• Access Wireless Setup Menu:
  • On the printer's control panel, touch the Wireless icon (or navigate to the Wireless setup option using the arrow keys).
  • Select Settings or Wireless Setup Wizard from the menu.
• Select Your Network:
  • The printer will search for available networks. Select your new Wi-Fi network from the list.
  • Enter your Wi-Fi password when prompted. Confirm the connection.

Update Printer Settings on Your Mac:

• Open System Preferences: Click on the Apple menu in the top-left corner and select System Preferences.
• Open Printers & Scanners: Click on Printers & Scanners.
• Add Printer:
  • Click the + button to add a new printer.
  • Your HP Officejet 4620 should appear in the list of available printers. Select it.
  • If prompted, install the latest drivers for your printer.

Verify Printer Connection:

• Print a test page to ensure that the printer is connected and working correctly.

Troubleshoot If Necessary:

• If the printer does not appear, make sure it's connected to the same network as your Mac.
• Restart both the printer and your Mac, and try the setup process again.
• Ensure your firewall or security software is not blocking the printer's connection.
