Trouble connecting HP Photosmart C4780 to wireless internet - WAP keeps timing out

HP Recommended
HP Photosmart C4780 series
Mac OS X 10.8 Mountain Lion

WAP keeps timing out - there is no IP address when I print the Wireless Network Test.

I have moved the printer closer to the router (google fiber) no luck. When I print the Network Configuration Page it discovers my network. But yet, no connection. I don't know what else to do, please help!

@GARCIA2, Welcome to HP Support Community!


You may need to instead go into your router settings and try changing the channel manually. Experiment with different channels to see which one works best.

  • Is your router dual-band enabled i.e., both 2.4GHz and 5GHz?
  • What is the distance between the router and the printer?
  • Could you perform a ping test using the Mac Network Utility and let me know the results?Use the printer IP address to perform a ping test, the printer IP can be located by selecting the wireless icon on the printer display.

Also, check with your Internet service provider if your router is able to forward 'Bonjour packets'. 

Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. The software comes built-in with Apple's macOS and iOS operating systems.


Keep me posted for further assistance.
