@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- Outdated firmware may cause authentication issues.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!
