HP Officejet printer keeps going offline only on Windows 10

Okay. I asked with wifi off and the printers working could you reproduce the screen shot in the first post.

Interesting how you have access to configure port. When I follow screens I don't have access.

Did you set up Epson same way. Do you have access to that port to configure it. Please don't change anything, just want to know if you have access.

Ken, actually on a network, the router does not look at packets between devices, when they are directly talking to each other. It is only when the devices have to communicate through a third device or outside of the LAN, then the Router handles traffic. In those cases where say a printer or other network output device is not immediately available, then the router takes over to figure out if the device is still connected and reports back to a computing device if say the printer cannot be found.

It's a mess of connections and needs sorting out.

Your HP Printer seems to have everything connected Wired Network, Wireless Network, WiFi Direct and USB, no wonder it is confused as it can only use one of those at any one time.

Assuming your Router is also the Wireless Access Point, the name gives the purpose.

Your 2 PCs connect ethernet cables to the Router 2 ports.

Then connect the two Printers to the Router/WAP either by Ethernet Wired port or Wireless depending on the Printers specs.

Forget about USB and WiFi Direct.

Connected via Ethernet, Wifi and Wifi direct are disabled. Wifi Direct is disabled if using Wifi connection to a network is active. When connected via USB, all connections have to go through the computing device (NAS, Desktop, Laptop, Server). Connection via Ethernet is best with the printer, Wifi if not able to make a ethernet connection (i.e., if the printer is located in a remote location that it is not easy to run Ethernet, or say POE devices do not work properly).

Okay keep Wi-fi off.

I wouldn't worry about name, until I reset my router one of my wired networks showed as a Wireless Name. Not sure where windows is pulling them from

So if as you said when the printer was working you did the screen shot and it looked the same nothing is using your e2400 Killer NIC.

I assume out the back of your machine you have two Lan ports, one for Intel and one for Intel (thanks to f14tomcat).

Is this correct?

If you are not using your e2400 Killer NIC you could

1) Uninstall e2400 Killer software or possibly prevent it from starting (Task Manager, Startup tab, disable E2400 if present)

2) Plug network cable into this NIC and see if this corrects it.


I might also investigate ensure printer is at Static IP address.


I assume you are using an Imaging software that allows you to backup device? I would be doing this before I made lots of changes. Easier to restore than rebuild.

Thank you again! I will try this tomorrow after my nightly backup with Macrium Reflect. I assume you meant 2 LAN ports; Intel & Killer. But I’ve never seen a Killer NIC, as far as I know. I thought it was just software that came with Win 10. I will take a look behind the computer to see if there’s an empty Ethernet port.

And, yes, the printers have a static IP address.

@phrab

Hi, phrab. Look at your previous post of the Device Manager. This is a snippet of that pic. You really do appear to have a Killer NIC, and it's enabled and healthy. So, there's a port back there somewhere. Have a look.



If you want to take the Killer totally out of the picture, disable it in Device Manager. Reboot.

Thank you. I totally missed that. I'm not sure if the Killer ethernet would be better than the Intel one or not. But if I uninstall e2400 Killer software or prevent it from starting (Task Manager, Startup tab, disable E2400 if present), then there'd be no point in plugging the ethernet cable into that NIC, right? I should first try plugging the cable into that port & then possibly decide which I want to keep.

The Killer or the Intel will either do just fine. Killer was designed (I believe) for networking gaming and such. It may add a level of complexity to your setup that you simply don't need. In any case, IMO don't have 2 hardwired NICS enabled and active at the same time. It just seems like trouble. Disable one then the other, and see which combo of hardwired and wifi works best. Doubt you'll see much difference. If no advantage to the Killer, disable and leave that way, and use Intel. You'll have to tinker.
