Whenever I try to scan it says it's lost wireless connection

[Flying_NEB]

I have a Laser Jet Pro MFP M479FDW.  Ever since I bought it, I've had issues with scanning.  

First, it wouldn't scan to a network folder, I could only use the email scan but it worked pretty much all the time. Then I moved across the country and got new internet (same router and modem) and then I couldn't do email scan anymore.  But, I figured out how to set up the network scan.  That worked for a few months and then it would say "unable to connect to network".  All the while, printing has never had an issue.  When this network problem would happen, sometimes if I unplug the machine and plug it back in, it would work. Other times I had to go back through the wizard to set up the wireless network.  It would scan to network folder then I'd try a second scan literally 2 minutes after the first one (the printer didn't even sleep) and it will say "unable to connect to network".  

Why is it having such a problem?  BTW, this is all done from the machine console which is what I like to use. I have used the HP app - which is cumbersome and annoying - and it seems to work.  But I shouldn't have to do all this garbage just to scan.

Hi @Flying_NEB,

Welcome to HP Support Community.

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

It sounds like you’re dealing with a frustrating issue with your HP LaserJet Pro MFP M479FDW losing its wireless connection for scanning. Here are several steps you can take to troubleshoot and resolve the problem:

**1. Check Network Stability

• Verify Network Connection: Ensure that your Wi-Fi network is stable and that other devices are connecting without issues. Intermittent network problems can affect your printer’s ability to stay connected.

**2. Update Printer Firmware

• Check for Firmware Updates: Outdated firmware can cause connectivity issues. Go to the HP support website and search for firmware updates for your specific model.
  • You can check and update the firmware directly from the printer’s control panel:
    • Go to Setup > Printer Maintenance > Update Printer.

**3. Reconfigure Wireless Network Settings

• Reconfigure Wi-Fi Settings:
  • On the printer’s control panel, navigate to Setup > Network Setup > Wireless Setup Wizard.
  • Follow the prompts to reconnect the printer to your network. Ensure that you enter the correct network credentials.

**4. Check IP Address and Network Configuration

• Verify IP Address: Check if the printer has a static IP or if it's getting an IP address via DHCP. Sometimes, IP conflicts or changes can cause connection issues.
  • Print a Network Configuration Page from the printer’s control panel to check the IP address and network status.

**5. Check for Interference

• Reduce Interference: Make sure there are no physical obstructions or electronic devices causing interference between the printer and the router.

**6. Reset Network Settings

• Reset Network Settings: Reset the network settings on your printer and reconfigure the wireless connection.
  • On the printer’s control panel, go to Setup > Network Setup > Restore Network Defaults.

**7. Verify Network Folder Setup

• Check Network Folder Settings: Ensure that the network folder settings are correctly configured:
  • Go to Setup > Scan > Network Folder Setup and verify that the folder path, username, and password are correctly entered.

I hope this helps.

Take care and have a good day.

I did all this before I ever contacted you.  As I said in the description of the problem, I reset the network and then and scan...once.  But as soon as I try again, even if it's within seconds, it loses the connection.  I can print just fine.  That tells me there's no issue with the network itself nor is there interference.
