Hi @GurramDhanu,

Welcome to The HP Support Community.  

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

I understand your HP OfficeJet 4630 won't connect to your WiFi using your MacBook Air, here are some steps to troubleshoot and resolve the issue:
 

Step 1: Reset Printer Network Settings

1. Reset Network Settings on Printer:
   • Go to the printer's control panel.
   • Select the Wireless option.
   • Choose Restore Network Settings.
   • Confirm and reset the network settings.

Step 2: Check Your Wi-Fi Connection

Ensure Wi-Fi is Working:

• Make sure your Wi-Fi network is functioning correctly.
• Ensure your MacBook Air is connected to the same Wi-Fi network you want your printer to connect to.

2.4 GHz Band:

• Ensure your Wi-Fi is operating on the 2.4 GHz band, as many printers do not support 5 GHz connections.

Step 3: Reconnect Printer to Wi-Fi

1. Use Wireless Setup Wizard:
   • On the printer's control panel, go to Wireless settings.
   • Select Wireless Setup Wizard.
   • Follow the on-screen instructions to choose your Wi-Fi network and enter the password.

Step 4: Restart All Devices

1. Restart Printer, Router, and MacBook Air:
   • Turn off the printer, unplug your router for 30 seconds, and restart your MacBook Air. Then reconnect everything and try to connect the printer again.

Step 5: Install Latest Printer Software

1. Update Software on MacBook Air:
   • Visit the HP Software & Driver Downloads page and download the latest driver or software package for your HP OfficeJet 4630.
   • Follow the installation instructions.

Step 6: Add Printer to MacBook Air

1. Add Printer in System Preferences:
   • On your MacBook Air, go to System Preferences > Printers & Scanners.
   • Click the + button to add your HP OfficeJet 4630.
   • Ensure your printer is listed and select it.

Step 7: Use HP Smart App (Optional)

1. Download the HP Smart App:
   • Download the HP Smart app from the Mac App Store.
   • Use it to connect and manage your printer wirelessly.
