Troubleshoot a Wi-Fi connection to an HP printer 

======================================

Network

The printer supports connection to a dual band network.

Create a separate SSID named network for the band / frequency want the printer to use and connect the printer to that network.

If not done, considering using a manual / static IP address to help stabilize the connection on the network.

Dual Band Network - Considerations

Reminders 

Some printers, particularly older models, only support 2.4GHz

Some printers support both 5GHz and 2.4GHz – but not at the same time

Regardless, if the printer won't work or cannot connect to your 5GHz frequency, try 2.4GHz.

If you are running a Dual Band Network,

 Check that the router is set up to broadcast all frequencies it supports.

Next,

If your router supports it,

 Create a separate SSID named network for each frequency (one for 5GHz and one for 2.4GHz).

and

 Connect the printer to the SSID network on the frequency / band you want it to use.

In general,

• 2.4GHz is less fussy about obstacles and supports a longer distance (separation) between router and device (printer)
• 5GHz is faster
