Please help!!! Homeschooling working from home.  This printer has been fine until we hooked up a new router and now it just won't connect. [Personal Information Removed].   Please 🙏🏼

Welcome to the HP Community --

There is no indication that the printer supports 5GHz.

If your new router is set to connect the printer at 5GHz, the connection will likely fail.

Make sure the router is configured to support both 5GHz and 2.4GHz - connect the printer to the separate SSID named network created for the 2.4GHz frequency.

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 named 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

Example – EWS – IPv4

Ink Jet Printer

EWS > HP Document / How-to

Use the HP printer Embedded Web Server (EWS)

Ethernet

Open your Browser > Type / enter the Printer IP address into URL / Address bar

Tab Network > Wired (802.3) > IPv4 Configuration

Wireless

Open your Browser > Type / enter the Printer IP address into URL / Address bar

Tab Network > Wireless (802.11) > IPv4 Configuration

As Available:

Tab Network > Wireless (802.11) > Advanced

Network Interface on / off, Network SSID name, Security Settings, Passphrase / Password

Select and connect to the correct SSID / network name for the bandwidth you are using.

Note:   It is not mandatory that you use a manual / static IP address.  Doing so can improve stability.

Example - EWS - Wireless > IPv4 Configuration

EWS_9025_Network_IPv4_Configuration_3

and

Example - EWS - Wireless > IPv4 Configuration > Advanced

EWS_9025_Network_Wireless_IPv4_Advanced_2
