HP ProOne 400 G1 AiO E8X86AV Ethernet speed capped issue

[sycomp]

Windows 10 Pro 64-bit Version: 17763.316

This unit's ethernet connection is somehow software capped at 10 Mbps. Viewing the configuration at Settings/Network and Internet/Change Adapter Options/[right-click]Ethernet/Status/ - in the "General" tab @ "Speed" the adapter is set at 10 Mbps.

I've installed HP Support Assistant and went through installing the drivers it recommended one at a time. The first driver was a chipset driver - this fixed the problem immediately, but after a reboot the problem returned. The next driver I installed using HPSA was the Realtek Ethernet driver. This fixed the problem until the last Windows update (Feature update to Windows 10, version 1809) was installed.

The latest BIOS is installed. The latest chipset/ethernet drivers are installed. I'm wonderning about any editable registry entries?

Any further assistance is appreciated.

Please try a clean install driver for the NIC

(a) Download the following driver and save on your computer,

       https://ftp.hp.com/pub/softpaq/sp89001-89500/sp89007.exe

(b) Go to Device Manager, Network and remove Realtek Ethernet driver and reboot,
(c) Right click downloaded file and select Run as administrator,
(d) Reboot again.

Regards.

Hello Banhein, thank you for your reply.

This is complete, however, the ethernet speed is still capped at 10 Mbps.

I wonder if there's a registry entry that controls the configuration? If so, where is it?

Well it would appear a solution has been had, however, how that solution was attained I cannot know.

This machine was a client's machine, one I was getting ready to install at their business. I had my spiel all ready to blame the latest Microsoft update (which originally did cause the issue here at my shop), however, when I installed the machine in the client's office, suddenly there the ethernet card configured itself for 1 Gbps.

Now the only difference between their hardware and mine is 1 x 1 Gbps switch and an older 1 x 100 Mbps switch. They connect their machine directly to their DSL router, which is the same as mine.

Interesting. Thanks to all who helped.
