Welcome to the HP Support Community. I'd be happy to assist you with the admin password issue.
Let's try these steps to restore the network settings to defaults -
1. From the printer control panel, touch and slide your finger across the screen, touch Setup, and then touch Network Setup. 2. Touch Restore Network Defaults, and then touch Yes. A message appears stating that the network defaults have been restored.
3. Touch OK.
If the issue still persists, I have sent you a private message with the steps to reset the printer. Check next to your profile Name, you should see a little blue envelope, please click on it.
Hope this helps! Keep me posted.
