Hi @Vero_Bob,

Welcome to HP Support Community.

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

It seems like you're experiencing issues with connecting your HP Officejet 4620 printer to your wireless network, possibly due to MAC address filtering on your router. Here’s a step-by-step approach to troubleshoot and resolve this issue.

Confirm MAC Address Filtering: Ensure that MAC address filtering is indeed enabled on your wireless router. You may need to log in to your router’s administration interface (usually accessed via a web browser with an IP address like 192.168.1.1 or 192.168.0.1) to check this setting.

Add Printer’s MAC Address to Allowed List:

• Find the MAC address of your HP Officejet 4620 printer. This can usually be found in the printer’s settings menu under network or wireless settings.
• Once you have the MAC address, log in to your router’s administration interface.
• Look for a section related to MAC address filtering or access control.
• Add the MAC address of your printer to the allowed list (sometimes called the whitelist). Save the changes.

Restart Router and Printer: After adding the MAC address to the allowed list, restart both your wireless router and the HP Officejet 4620 printer. This helps apply the changes and ensures a fresh connection attempt.

Reconnect Printer to Wi-Fi:

• On the printer, navigate to the network settings.
• Choose the option to connect to a wireless network and select your Wi-Fi network from the list.
• Enter your Wi-Fi password if prompted and follow any additional instructions on the printer’s screen to complete the setup.

Test Connection: Once the printer shows as connected to the Wi-Fi network on its display, try printing a test page from a computer or device connected to the same network. Ensure the printer responds correctly.

If you’ve already attempted these steps and are still encountering issues, here are a few additional troubleshooting tips:

• Update Router Firmware: Sometimes, updating your router’s firmware can resolve connectivity issues and improve compatibility with devices like printers.
• Disable and Re-enable MAC Filtering: Temporarily disable MAC address filtering on your router, reconnect the printer to Wi-Fi, and see if it connects successfully. If it does, re-enable MAC filtering and add the printer’s MAC address to the allowed list again.
• Factory Reset: As a last resort, you can perform a factory reset on both the printer and the router. This will erase all custom settings, so use it only if other methods haven’t worked.

If these steps don’t resolve the issue, there may be a deeper compatibility problem or a specific setting that needs adjustment in your router’s configuration.

I hope this helps.

Take care and have a good day.
