Printer asks for password when changing WiFi

[Sonia1512]

I have a new router and want to change my printer but it asks for a password.  I haven’t had a password and am stressed that I can’t resolve this !  I have a laser jet m280

Hi @Sonia1512,

Welcome to HP Support Community.  

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

When your Wi-Fi network name or password is changed, you need to reconnect your printer to the network using the new login credentials.

Reconnect the printer from the wireless settings on the control panel (if available), use Wi-Fi protected setup (WPS) with supported routers, or install the HP Smart app for a guided setup.

Printers with a touchscreen control panel: Open the Setup, Network, or Wireless settings menu, select Wireless Setup Wizard, and then follow the instructions to select the network name and enter the password.

Printers without a touchscreen control panel: Press and hold the Wireless button for five seconds or until the wireless light starts to flash. Within two minutes, press and hold the WPS (Wi-Fi Protected Setup) button on the router until the connection process begins. The printer wireless light stops flashing when the connection completes.

HP Deskjet 6000 and 6400, ENVY 6000 and 6400, and Tango printers: Press and hold the Wi-Fi button and the Power button on the back of the printer for five seconds until the blue bar flashes. Within two minutes, press and hold the WPS button on the router until the connection process begins. The blue bar stops flashing when the connection completes.

Go to HP printers - Wireless connection is lost after router or network settings change for more information and additional methods to connect to the network.

I hope this helps. 

Take care and have a good day.
