Wits end on connecting old printer to new modem

[jayp1212]

I have pressed all the buttons, printed all the trouble shooting steps. Downloaded HP apps possible.  I cannot figure out in plain English and no digital display how to get my new modem and my printer to connect. I’ve spent days on this!!!

Welcome to the HP Community --

"All" is a lot and I don't pretend that I know your printer.

I can offer some ideas -- perhaps there is something here that you have not yet covered.

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

The following is a good place to start --

Included (and certainly not limited to):

• How to set the printer back to network defaults
• An FAQ subject on failed connections after the router is replaced

What else?

One thing that might not be obvious if you were previously using an older single-band router and have moved to a dual band network:

This printer supports 2.4GHz only -- it will not (cannot) connect to 5GHz.

Dual Band Network - Considerations

Reminders 

Do not ignore your router --

A router that is weak, outdated, poorly located, or incorrectly configured can cause all sorts of odd network behavior issues.

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

Manual IP Address

EWS > HP Document / How-to

Use the HP printer Embedded Web Server (EWS)

NOTE:  Find printer IP address

Section How do I manually assign an IP address to my printer?  Items 1-2

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.
