New WiFi password, now printer won't work

[Montgomeryat2]

Just bought my HP 3634 printer, and it worked fine. Downloaded the drivers and we were good to go. Our router had an issue and we changed the password...now I can't figure out how to update that info for my printer and it will not print.

Unplugged printer, router, computer and hard reset...nothing. Tried to link WiFi on printer by WPS on router...nothing. the HP website keeps running me in circles. I'm not advanced and just need to figure out how to print! This is beyond frustrating. At least my 4500 had a screen for info 😕

Replacing/reconnecting/changing your wireless router, try here.

* Reset your printer back to Network Defaults.  Then run the Wireless Setup Wizard to connect.  Both can be accessed from the front panel or computer.  If no front panel for configuration, you must use your Printer USB cable to connect.  You can also try the WPS method if your router/printer supports this only if the Wizard or Printer USB cable is not available.  Read your User Guide for info.

* Wireless printers only connect to the 2.4G band in your router.  The router must have the 2.4G SSID band enabled with a different SSID name than your 5.0G SSID band in your router.

* Set router to a fixed wireless channel like 1, 6 or 11, never ‘auto’.  Try channel 1 first then the others one at a time.  

* Make sure printer and router are at least 5 feet apart.  

* Make sure IPv6 is disabled in the printer.

Make and model of modem and router?

However if you have a Gateway (modem+router) device, all Gateway devices are terrible for wireless connectivity.   If this does not work, suggest you think about putting that gateway device in full bridge mode and install your own high quality router that YOU have full control over.
