Unable to set up HP LaserJet Pro MFP M29w

[lana34]

I moved apartments and I'm unable to set up my printer, now that it is connected to the new wifi. I  was unable to set it up using HP Smart. So, I installed the driver from HP easy start and it works. I can print using the USB cable. The printer is connected to the same wifi as my Mac. But I can't add it to HP smart. Any suggestions?

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, to provide an accurate resolution, I need a few more details:

• Is your router dual-band enabled i.e., both 2.4GHz and 5GHz? If yes, make sure the dual-band has different SSIDs for 2.4G and 5G networks.
• What is the distance between the router and the printer?

This printer supports WPA encryption, check if the router is on the same encryption method. If using WEP or WPA-PSK+FT change it to WPA-PSK

In addition, perform a ping test to check the connectivity:
 

1. Click Applications > Utilities > Terminal.
2. type ping "IP address" and press enter

Wait until 10 pings have been performed and then press ctrl c on the keyboard and hit return. 
The results will appear. Share the ping test results.
 

The wireless status menu on your Mac should also give us quite a lot of information that would help us identify the issue. You can press and hold option-click the Wi-Fi icon and then use shift-command-5 to take the screenshot. Press the space bar when the icon turns into a camera. Share the ping test results and the screenshot with us.
 

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. 
 

Hope this helps! Keep me posted for further assistance.

I would suggest you restore the printer to original wireless setup: https://h30434.www3.hp.com/t5/Printers-Knowledge-Base/How-to-Restore-WiFi-Setup-mode-on-HP-printers-...

In terms of 5 Ghz and 2.4 Ghz, it is often the case with newer Wifi routers that they do not connect reliably so the information posted by @Echo_Lake is correct. Only note to that is you want to allow the printer to only connect to the 2.4Ghz SSID.
