HP Photosmart 7520 won’t reconnect to wireless network.

[TXCool]

I was gone for the weekend and now I can't print. What I believe happened is that we had a power outage and my Ring, Echo and printers have lost the connection to WiFi. I think I need to reenter the siteID password. No matter what I do I cannot reconnect to my WiFi nor could I do a factory reset of the printer. Factory restore does not work either. Connecting iPhones, iPads and MS desktops do reconnect. I'm at a loss as to what to do. Please HELP.

You may need to reset your printer.

Disconnecting the USB or ethernet cable may still leave the printer in the wired mode. Connecting an ethernet cable may still leave the printer in Wi-Fi mode. The Wi-Fi reset shown below is used to put Wi-Fi printers into setup mode. Note that the reset video may show a slightly different model than yours.

The steps below are Wi-Fi only and do not perform a factory reset:

1. Touch the Setup or Menu icon on the printer's control panel
2. Touch Tools, or Printer Maintenance > Restore
3. Touch Restore Factory Defaults > Yes or Continue

Wi-Fi connection

Ideally, your Wi-Fi printer should connect to the modem or router. If your network has multiple boosters / repeaters, it is possible the printer may connect randomly to any of the units. The modem needs to provide the same IP address on every connection. This rarely happens with random connects. An alternate Wi-Fi connection is Wi-Fi direct. Your laptop or smartphone prints directly to the printer and does not go through the modem.

Wi-Fi Direct is explained on page 49 of the User Manual, this Wi-Fi setup avoids configuring the modem.
A simple connection to the modem can be done by using the WPS pushbutton method. This is explained on page 47 in this User Manual.
