Yeah, this one's common. The timing window for WPS is very short. You have to press the router's WPS button within two minutes of starting the process on the printer.
Here's the exact sequence:
- Make sure the printer and router are close to each other.
- On the printer control panel, press and hold the Wireless button for at least 3 seconds. The Wireless light will start blinking.
- Within 2 minutes, press the WPS button on your router.
- When connected, the printer's Wireless light will stop blinking and stay lit.
- Then, open the HP Smart app, tap the Plus icon or 'Add Printer,' and follow the prompts to add it to your network and register it.
If that didn't work: Your router might not have a WPS button, or WPS might be disabled. Skip WPS entirely and use the HP Smart app for setup. Go to 123.hp.com, download the app, and it will guide you through the standard wireless connection process. It's often more reliable.
If the light blinks forever, the connection failed. You'll need to restart the process or use the HP Smart app method.
