Won't connect to internet

[benhak618]

I have an HP LaserJet Pro 200 MFP M276nw that stopped connecting wirelessly.  I get the message that the WPA authentication method on your HP printer has been changed from the default setting.  When I go into the printer settings and display the passphrase it is the exact same passphrase I enter when I try to configure wirelessly.  I have searched various workarounds and cannot find the solution.

@benhak618, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding a connection issue 

We're thrilled to have the opportunity to assist you and provide a solution.  

 It sounds like your HP LaserJet Pro 200 MFP M276nw is experiencing a WPA authentication issue, possibly due to a security setting change or compatibility issue. Here are some troubleshooting steps to resolve this:

Restart Everything

• Power cycle your printer, router, and computer.
• Turn off your printer, unplug it for about a minute, then plug it back in and restart.
• Restart your router and computer as well.

Forget and Reconnect the Network on Printer

• On the printer, navigate to Setup > Network Setup > Wireless Settings.
• Select Restore Network Defaults, then restart the printer.
• Go back to Wireless Setup Wizard and try reconnecting with the correct passphrase.

Manually Assign IP Address

• If the printer previously connected but doesn’t now, assign a static IP.
• On your router, find the printer’s MAC address and assign a manual IP.
• Alternatively, during Wi-Fi setup on the printer, try entering the IP address manually instead of DHCP.

Update Printer Firmware

• Outdated firmware may cause authentication issues.
• Download the latest firmware from HP’s support website:
  HP Support for LaserJet Pro 200 MFP M276nw
• Install the firmware update via a USB connection if the printer isn’t connecting wirelessly.

Try a 2.4GHz Connection

• If your router supports dual-band Wi-Fi, ensure the printer is connecting to the 2.4GHz band instead of 5GHz.
• Some older HP printers don’t support 5GHz networks.

Reset Printer Network Settings

• If nothing else works, perform a full network reset:
  • Go to Setup > Service > Restore Defaults.
  • Select Restore Network Settings and confirm.
  • Reconnect the printer to the Wi-Fi. 

Hope this helps!

Take care, and have an amazing day!
