Hi @Molly154,

Welcome to the HP Support Community.
 

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

I'm sorry you're facing this wireless connectivity issue with your HP ENVY 6400 All-in-One printer. I know how frustrating it can be, especially when you're in the middle of something important and the printer just won’t connect. Let’s walk through this together, step by step, and get your printer back online.

Step-by-Step: Reconnect Your HP ENVY 6400 to Wi-Fi

Here’s what you can do to restore the wireless connection:

1. Restart Everything

• Power off your printer, router, and computer or mobile device.
• Wait 30 seconds, then power them back on, starting with the router, then the printer, and finally your device.

This refreshes the network and clears temporary glitches.

2. Check Wi-Fi Signal

• Make sure your printer is within 5 feet of the router.
• Avoid placing it near metal objects, microwaves, or thick walls that can block signals.

You should see a solid blue light on the printer’s wireless icon. This means it's connected.

3. Reconnect Using HP App

• Download HP App – For HP Printers, Laptops, and Tech Accessories | HP® Official Site.
• Tap “+” to add a printer.
• Follow the on-screen instructions to reconnect to Wi-Fi.

If prompted, enable Bluetooth and Location Services. This helps the app find your printer.

4. Reset Wireless Settings (if needed)

If the printer still won’t connect:

• Press and hold the Wireless button and the Cancel button on the printer for 5 seconds.
• This will restore network settings to the default.
• Then retry setup via the HP app.

5. Use HP’s Official Troubleshooting Guide

HP has a detailed support page tailored for your printer model. You can find step-by-step help here:

I hope this helps.

Take care and have an amazing day!
