HP Photosmart C4780
Microsoft Windows 10 (64-bit)

I was forced to change my Network Name & Password when my Internet Provider replaced my old Modem/Router. 

Now I can't connect my HP Photosmart C4780 printer since my wireless Network Name and Password has changed. 

I do not have a USB Cable and am looking for a quick fix without using a USB cable...

Download your User Guide here.

You can try WPS push button method if your router supports this.  If not, you will need your Printer USB cable.

HP Recommended

Do you have step by step instructions for WPS mode? 

HP Recommended

Yeah, it's in the User Guide.

Thanks!  I downloaded the users guide & found the instructions.....

I do have a WPS button on top of my new router (yay) 

 

I followed the instructions:

 

 To connect the HP Photosmart using WiFi Protected Setup (WPS)

  1. Do one of the following:

 Use Push Button (PBC) method

  1. Set up wireless connection.
  2. ❑ On the Home Screen, press button next to Scan.
  3. ❑ Press button next to Wireless Menu.
  4. ❑ Press button next to WPS.
  5. ❑ Press button next to Push Button.
  6. ❑ Press corresponding button on WPS-enabled router or other networking device.
  7. ❑ Press OK.

I am getting an error on the printer screen after doing the above steps...but it's NOT telling me what that error is!  Any suggestions?????

HP Recommended

OK, if the WPS method is not working for you, you need to use your Printer USB cable and connect.

HP Recommended

Thanks!   I was afraid you'd say that, since I can't locate the USB cable for the printer........Wish me luck!   

HP Recommended

Can you walk me thru (step by step) how to change the network name using the USB cable? 

HP Recommended

Yes.  The step by step procedure is in the User Guide above.
