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A router that is weak, outdated, poorly located, or incorrectly configured can cause all sorts of odd network behavior issues.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

Wireless

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

EWS > HP Document / How-to

Use the HP printer Embedded Web Server (EWS)

NOTE:  Find printer IP address

Section Open the EWS over a local network orientation

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.
