Will HP ENVY Pro 6400 All-in-one run in Windows 11

[Rhonda3385]

I just downloaded Windows 11 and now I can't connect to my wireless printer and wanted to know if this could be the problem?  I've been through troubleshooting, etc., but it still won't connect.

Welcome to the HP Community --

Printers in this series are quite happy to connect to and run printer software in Windows 11.

So -- the issue perhaps lies elsewhere.

If the printer remained on your network during your OS changes to the computer, the printer might be convinced it is still connected to whatever system and / or Operating System you were using prior to downloading (and installing) Windows 11.

2) Dual Band Network - Considerations

Reminders 

If the printer supports it, connecting using Ethernet is generally a better choice.

Some printers, particularly older models, only support Wireless at 2.4GHz

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

Regardless, if the printer won't work or cannot connect to your 5GHz SSID named network, connect to the 2.4GHz network.

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,

On your router:

 Create a separate SSID named network for each frequency supported by the router

 What?  Create one SSID named network for 5GHz and one SSID named network 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
