Hi shah_apple,
I am sorry that you are still having a connection issue. I suggest power cycling your network.

Follow these steps to reset your HP printer, your wireless router, and your computer.
1.Press the Power button on the HP printer to turn it off.
2.Disconnect the power cord from the rear of the HP printer.
3.Disconnect the power cord from the wireless router.
4.Turn off the computer.
5.Wait 30 seconds.
6.Reconnect the power cord to the wireless router.
7.Wait 30 seconds, or until the router is fully on and ready.
8.Turn the computer back on.
9.Wait for the computer to reload.
10.Reconnect the power cord to the rear of the HP printer.

If you are still having an issue then I recommend Uninstalling the Printer Software,
