I recently changed my ISP from Frontier to Comcast. I ran the Wireless Setup Wizard from the printer, which found the new Host and I entered the new WiFi passcode. The printer's Wireless Light and WiFi Direct Light are both lit. However, the computer cannot see the printer - claims it is offline. Running the HP Print/Scan Doctor results in failed to communicate with the printer.
When Frontier was my ISP, the IP addresses of devices on the network were of the form 192.168.1.X. Now under Comcast, the IP addresses are 10.0.0.X. The Wireless details displayed on the printer continue to show its IP address as 192.168.1.9, which cannot be correct. I tried unistalling the printer and reinstalling it, but the problem remains. The Network Name is correct, The Host Name is correct. The signal strength is excellent.

As you can see: printer still "thinks" it is connected to old 192.169.1.x range, :

Please also note: Your printer may only support 2.4GHz therefore you need to check and allow your router to broadcast both (dual) bands which are 2.4GHz and 5.0GHz.
