Microsoft Windows 10 (64-bit)

hi

My computer is connected to my router via ethernet cable and working fine, my printer is wireless and is also connected to my router via wifi.

I cannot get my computer to install the printer.

If i unplug the ethernet on the computer and use the computers wifi i can install it and it works but if i then go back to the ethernet connection, turning off the computer wifi the printer becomes offline and i cannot use it.

I can print to the printer from my iphone ok so i know the printer is connected to the router correctly.

It was working before but has suddenly stopped, i have uninstalled the printer and reinstalled it and tried every troubleshooting in the HP site i can find but i cannot get it to work again.

 

Anyone have any ideas appart from use the computer wifi as i do not want to do the as i want the computer connected via ethernet to the router

@billywizzo, Welcome to the HP Support Community!

 

It seems like the printer and the computer are not connected to the same network when the computer is connected via ethernet cable. As the printer is working fine when the computer is wirelessly connected, it means the printer is working fine.

The IP address of both devices should be in the same range.

 

Obtain the IP address of the printer while the computer is connected via ethernet cable and try to access its EWS page.

By this, we can determine if the connectivity is fine.

  • Obtain the IP address of the printer – You can touch the “wireless” icon on the printer control panel to obtain the IP address.
  • Type the IP address at the top of your web browser to obtain the printer EWS page on your computer.
  • If you get any security notification, click on show details/advanced and 'proceed to this website'.

Hope this helps! Keep me posted.

I cannot access the printer using its IP address in a browser window when using the ethernet connection (ethernet cable plugged in) but I can get to it if I use the computers wifi connection (ethernet unplugged).

I am not sure if it something to do with the Sky hub/router as it used to work but now does not via ethernet.

Or if it is due to one of the windows updates that have been installed.

If you are not able to reach the EWS page of the printer using the IP address, this is a connectivity issue with ethernet connection and the IP address is incorrect/invalid.

 

Try using a different ethernet cable. Kindly refer to the steps in this document to connect the printer using an ethernet cable.

Also, while the ethernet cable is connected, run a wireless test on the printer.

Go to Setup > Network > print test report.

 

Let me know how this goes.
