I have an HP Photosmart All In One C4580 printer and I am having difficulties printing wireless.
I used to be able to print fine wirelessly. However after a while it stopped working. When I printed a Wireless Network Test Report it gave me the results. It said this:
“Your wireless router requires a WPA security passphrase. The passpgrase configured on your HP printer did not match exactly. Run the wireless network set up to re-enter your wireless network WPA security passphrase.”
I am having difficulties at this part. Please can anyone guide me through this step by step? I have tried many things and I can’t seem to figure this out.
