No Ethernet on HP 3005pr USB 3.0 Port Replicator

[Ken_B]

Hi all,

I'm having trouble to get Ethernet connection with HP 3005pr USB 3.0 Port Replicator. Basically it does not recognize the LAN cable when inserted and I don't get Internet connection. The LEDs on the bottom of the port do not light up. In Control Panel of Windows, it can see the adaptor ("HP USB Giga Ethernet") and it says "Network cable unplugged".

Troubleshoot I did so far:

Upgraded the driver to the latest version from the HP website

Rebooted my laptop

When the same cable was connected directly to the laptop, I got Internet connection.

Used a different cable.

Checked the port. No sign of visible damage.

Tested other ports. USB 2.0 and HDMI ports are working fine.

Tried the minimal connection (just LAN and power cables). LEDs underneath the LAN port didn't light up.  

Get a replacement from HP. The same issue.

To me, it's a hardware issue, not a software issue. That's why I got a replacement, but I'm still having the same issue. It's difficult to imaging that two different units are broken in the same place.

Things I want to know:

What happens if you just connect power and LAN? Do the LEDs light up, just like when you hook up a LAN cable to a PC that is turned off? If so, then I need to get yet another replacement from HP. Mines don't light up no matter what I do. 

I appreciate any comment/suggestion on this.

Thanks,

Ken

Hi REO,

Thanks for your comment.

Do you have any specific reason that you suggested this version of the driver?

The version I had in my laptop was newer and I needed to uninstall it first. Anyways, I'm still having the same issue with the driver version you linked.

Thanks,

Ken

Hello,

I had a similar problem that I resolved by completely removing the displaylink software and reverting to the original Port Replicator drivers that were pre-loaded in the hardware.

I started having the same problem suddely with my HP port replicator. It had worked fine for two years and then sudden, one day, the ethernet stopped working. Mine would show that the LAN was connected but said "No Internet". I tried all the usual tricks and nothing seemed to work. It finally and randomly started working last night after I updated the DisplayLink software and I thought it was fixed. Sadly, today it worked for a while and then dropped off again.

I found the following suggestion in a different HP thread for laptops with this issue, and gave it shot. Low and behold, my ethernet immediately came back to life. It's working now and hopefully it stays that way 🙂 Below is the link and the verbiage from the oher thread that worked for me:

From the Start Menu, open All Programs, open Accessories, right click the Command Prompt and select 'Run as Administrator'.  Into the prompt, type the following commands, hitting enter after each command.  Include spaces in the commands where shown:
