Tried ethernet cable install, usb install, node name install, Push button router install, all for wireless installing. Not connecting. Everyone's household devices can't print now either.
And you've checked the manual for the printer, right?
Have you deleted the printer from your computer and then installed it back again?
When I changed gateways, I used the same ssid and password and my printer worked right away, if you changed them you will have to enter the new info into the printer
