I completed the steps in the video and got the pint out page, but the WiFi button is now blinking blue  (power button is no longer flashing) and it’s not connecting to my network. When I use the HP software to ‘add a new printer’ it cannot find the printer to join my network, and my Bluetooth on my phone doesn’t find it either.

Bluetooth is only used by HP Smart to configure the printer.  Only Wi-Fi is used for printing.  Do not attempt to pair your phone with the printer.

Watch the reset video or perform the steps. After resetting, you generally have 2 hours to complete the setup. Decide if you want to connect the printer to the router or to print directly to the printer and bypass the router.

Many HP and other OEM printers have problems with the router when the router has two bands and both bands have the same name (SSID). Log into the modem and rename one of the bands. Alternately, contact your ISP and have them rename a band.

Or simply use Wi-Fi direct.

If English is not your native language or if you wish to get additional information not covered below, then use the HP and Microsoft support assistants. The latest HPSA supports 36 languages and can be downloaded here. Microsoft's AI assistant is in the latest Windows 10 and 11 releases and there are instructions here on how to enable the AI. Microsoft's AI assistant (Copilot) has a microphone button and supports natural language processing.

Do not call any phone numbers shown in any of the videos or revealed by a Bing or Google search unless it is an HP site or video.

Let me know if you have a flex system (Wi-Fi boosters or repeaters) as the setup is much more complicated for routers.
