OfficeJet Pro 6978 wifi no longer connected

HP Recommended

Hi, my office jet pro 6978 is no longer connected to my network as it was this morning.  I'm getting error 9923.  I'm on iMac running Mojave 10.14.6.  I tried resetting printing system.. no luck.  Printer's WiFi light is not on.  It's like the Wifi has been turned off on the printer.

@TXLakeGirl, Welcome to the HP Support Community!

 

On the printer screen, go to Setup > Network Setup > Restore network settings

Network System preference > Advanced > Configure IPV6 > Automatic  

Go back to Network > Wireless > Wireless setup wizard and select your network.

  • Make sure the printer and the MAC are connected to the same wireless network.
  • This printer supports only 2.4GHz network. So, the MAC should be on the 2.4GHz network.
  • If you have a Dual-band router and both 2.4GHz and 5GHz networks share the same name/SSID, the printer will not be able to connect to the network. In this case, contact your Internet service provider to assign different names to both the networks.
  • Also, check with your Internet service provider if your router is able to forward 'Bonjour packets'.

Try printing.

 

Hope this helps! Keep me posted.
