Unknown Laserjet M252dw Printer password

[Martin1952]

Recently had my router updated by my service provider (BT). SSID changed, so unable to print to my HP Color LaserJet M252dw. I have tried to change the settings, but whether I am doing a Network setup or a System setup, I am asked to input a password. I have tried numerous passwords that I use for my messaging, MS password etc, but each comes back as Password Invalid.

I have installed HPPSdr.exe, but this doesn't help.

I have my new router password and SSID, but these also do not work. Please advise anyone?

Hi @Martin1952,

I'd like to help!

Access the Wireless Setup Wizard through the printer control panel to establish a wireless connection between your printer and network.

1. From the home screen of your printer control panel, touch the Wireless icon .

2. Touch the Setup icon .

3. Touch Restore Network Defaults or Restore Network Settings, and then touch Yes to confirm your selection.

4. After the default network settings are restored, touch the back arrow, touch Wireless Settings, and then touch Wireless Setup Wizard.

   The printer searches for available networks.

5. Touch the name of your wireless network.

6. If your wireless network does not display in the list of wireless networks, touch Enter New Network Name, and then type the name of your wireless network.

   NOTE: 

   Type the exact network name, including any uppercase and lowercase letters.

7. Type the WEP or WPA key (network password), and then touch Done.

   If you do not know your network password, go to Find Your Wireless WEP, WPA, WPA2 Password..

   Once the printer connects to the wireless network, the blue Wireless light on the control panel turns on solid.
