OfficeJet Pro 9015 suddenly has no wifi connection and is constantly offline

[jbradshaw]

Have had this printer for a few years with no problem.  Out of the blue, it has gone offline and acts like there is no wifi b/c it constantly gives me a message that "An Ethernet cable has not been detected.  Make sure that both ends of the cable are inserted correctly."  We have never used this printer on an ethernet cable.  I have tried doing a factory reset and no matter what I do it says the printer is offline.  Nothing has changed with our home wireless internet.  Everything else is working fine.  How do I get the printer to connect wirelessly?  In the network configuration page, it says "you cannot use the device's wireless function because it has been disabled."

How do I re-enable it?

Hi @jbradshaw,

Welcome to the HP Support Community. 

I'd like to help!

Perform these steps below:

This document is for HP printers that support both wireless and USB connections.

NOTE:

For Chromebooks, go to HP printer setup (Chromebook) for steps to connect the printer.

Remove the USB printer from the computer

Disconnect the USB printer from the computer, and then remove it from HP Smart if necessary.

Turn off the printer, and then turn off the computer.

Disconnect the USB cable from the printer and the computer.

Turn on printer and the computer.

Close any device setup prompts that display on the computer.

If you previously used HP Smart to set up the USB printer, remove the printer from the app.

On the app home screen, right-click the printer name and then select Forget This Printer.

Install the HP Smart app

Get the HP Smart app for Android, Apple iOS or iPadOS, Windows, and Mac.

Download the HP Smart app from 123.hp.com (Android, Apple iOS, iPadOS), HP Smart - Microsoft Store (Windows), or HP Smart - Mac App Store (Mac).

If you are prompted to sign in with Microsoft to use the app across devices, you can sign in or click No, thanks to continue.

NOTE:

Disconnect from a Virtual Private Network (VPN) connection before downloading.

If you are setting up HP Smart for the first time, you must create or sign in to an HP account to access all printer functions.

Set up your printer using the HP Smart app

Add your printer to HP Smart and follow the guided setup to connect to your computer or mobile device.

NOTE:

For HP+ printers, there might be additional guided steps required to complete printer setup, such as HP+ choice selection and HP account creation.

If you are setting up the printer on a Wi-Fi network, prepare the printer for setup.

Place the printer and the computer or mobile device near the Wi-Fi router.

Turn on Wi-Fi on your computer or mobile device and connect to your network. If the computer is connected to the network with an Ethernet cable, temporarily disconnect the cable and use the Wi-Fi connection during the setup.

Enable Bluetooth on the computer or mobile device so that HP Smart can detect the printer during the setup.

For Windows computers, turn on Windows Update to make sure Windows is always up to date.

After installing HP Smart for iOS and Android, enable the mobile device location service and allow the app to use your location to detect the printer and offer solutions during setup.

Multiple printers within range of your device might display during setup. Make sure to select the correct printer. Do not select a printer with DIRECT in its name, as it is only for Wi-Fi Direct connections.

Open HP Smart.

If this is the first time you are opening HP Smart, the app attempts to detect and set up the printer.

If this is not the first time you are opening HP Smart, click Add Printer or the plus sign to find the printer.

On the connection type screen, select Wi-Fi, USB, or Network. The options displayed vary depending on your computer or mobile device. Follow the steps to complete the setup.

If you are using a Wi-Fi connection and your printer is not found, continue to the next step.

Restore Wi-Fi setup mode.

Most printers with a touchscreen display or menu: Open the Wireless or Setup menu, select Network setup or Settings, and then select Restore Network Settings.

Printers without a touchscreen display or menu: Go to Restore Wi-Fi setup mode on your HP printer to restore default settings by pressing the buttons on your printer.

Within two hours, close then re-open HP Smart, and then add the printer again.

Follow the guided setup screens to complete the printer setup.
