HP Envy 6455 goes offline from wifi net due to inactivity. How can I keep it online?

[souch]

The printer goes offline from wifi network after several days of no use. This requires unplugging it from the back,  hitting the reset button, plugging it back in and going through the reset process. I want it to be active always. One HP suggestion was to go into advanced settings. I'm unable to find that pathway when accessing HP Smart app on my Mac. 

What do I have to do to keep the printer always online?

Welcome to the HP Community --

Perhaps the "Advanced" section refers to accessing the Embedded Web Server (EWS) from within HP Smart.

I don't have any MacOS in the home office -- I can provide examples for HP Smart Windows and iPadOS.  One of these might be similar enough to help.

Example - HP Smart - Mobile - iPadOS - Home Screen

HP_Smart_Mobile_Main_Menu_17

Example - HP Smart - Windows - Home Screen

HP_Smart_Win_Main_Menu_4

You can (instead) open EWS in your browser.

At least on an iPad, Safari works for this.

More on this later in the message...

Offline Condition

Although the printer appears to be switched on, it does not communicate with other devices on your network.

Consider >> Restart All

Restart Everything, including the router that controls your network

Offline - Known solutions, presented in the order to be completed / considered

  HP printer is offline or not responding - Windows / Mac  

Section “Advanced Troubleshooting” > Solutions specific to Windows / MacOS / HP Smart (Printer Unavailable)

AND

Troubleshoot a Wi-Fi connection to an HP printer 

Additional Information / Comments / EWS

Make sure -- if your router supports the option -- that your printer is connected to the named SSID network for the frequency / band you want it to use.

What?  Printer supports 2.4GHz or 5GHz , though not at the same time and the printer might not be able to "Hop" from one band to another.

Assign the printer its own manual / static IP address.

Not sure if there is such a thing in MacOS -- if yes, change the printer connection type to TCP/IP

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

Example – EWS – IPv4

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 - Network - IPv4

EWS_9025_Network_IPv4_Configuration_3
