WiFi Password changed, i cannot connect my printer to the WiFi network

[Carmen18]

I have changed my router password and I need to reconnect my HP DeskJet Ink Advantage 3790 printer to the same network and WiFi but to change the password, but cannot figure out where to go to find this information.  Every time I go through the set up via the HP Smart app, it tells me that it cannot connect.  I am not able to connect my computer via USB to print - this model does not have display or USB.  I have been trying to figure this out for a few hours now and am at a complete loss.  Any help would be greatly appreciated!

Thank you!

@Carmen18, Welcome to the HP Support Community!

Use WPS to connect the printer to your wireless network.

1. Locate the WPS button on your router, but do not press it yet.

   If your router does not support WPS, skip to the next step to connect the printer with the HP Smart app.

2. Turn on the printer. If the printer is in sleep mode, press the Cancel button on the control panel.

3. On the printer control panel, press and hold the Wireless button  for at least 3 seconds or until the wireless light starts to flash.

4. On the router, press and hold the WPS button for 3 to 5 seconds or until it shows that the WPS connection process has started.

   NOTE: 

   The printer stops searching for a WPS connection two minutes after the wireless button is pressed. If you were unable to press the WPS button within that timeframe, attempt these steps again.

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