Envy 7755 Won't Connect to WIFI network

[B-K-Newcastle]

Printer was working perfectly on our wifi network before we lost our internet for 4 days. On restart it shows offline although it seems to be correctly set up for the network. The password and network are ok although getting to the settings on the screen was accidental. I tried many times but just somehow stumbled on the screens and was able to confirm. Don't know how to get back to the screens. I can hook up with a cable and printer works just fine but once I disconnect the cable the status shows offline even though the wifi is on the settings seem correct. Have unplugged and restarted everything several times How can I get back online on wifi?

@B-K-Newcastle, Welcome to the HP Support Community!

I understand the wireless connectivity between the Mac and the printer is not working. 

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

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. Either 2.4 or 5GHz 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.

Perform a ping test to check the connectivity

1. Obtain the IP address of the printer by clicking on the Wireless icon on the printer
2. Open a new Terminal window (it's located in Applications > Utilities, or you can just start typing it in Spotlight).
3. Enter “ping” followed by the IP address of the printer. 
4. Press Return. Press ctrl C after 10 pings
5. There should be 0% packet loss, share the results in your next post.
