Solved: NUC11PHBi7 ethernet slow

insecticide · ‎08-16-2021

I have a fresh install of Windows 10 Pro build 19043 on a NUC11PHBi7.

The ethernet port give 0.5mbs while WiFi is 800mbs on a gig switch/network. I've tested another computer on the same switch with the same cable and it is up to speed.

I have used the driver assistant to update the drivers including the network controller.

Anyone have any idea what is going on with the Ethernet port/driver on this model?

First thing you should have done after installing the O/S is to manually install the Chipset Device Software (a.k.a. INF Update) and Management Engine packages. From there, you can either install and run the Intel Driver and Support Assistant (iDSA), which will automate the driver installation from there, or you can install the other driver packages manually (downloading from here: https://www.intel.com/content/www/us/en/search.html?ws=related#q=nuc11phbi7&t=Downloads&layout=table).

Hope this helps,

Thanks Scott, what you suggest makes perfect sense. I installed the Chipset device software as you mentioned and deleted the Ethernet adapter entirely from the OS, reinstalled it, and rebooted. The adapter behaves the same.

Odly, Windows reports a 10/10 link which is obviously not correct. I'll need to keep digging but thanks for your help!

Cheers,

Bill

Hhmmm, you may have a failing (or noisy) component. If all else fails, get the unit replaced. If you are still in the first month, you should be able to get the unit replaced via the storefront that you used. If that isn't possible, there is always the RMA route with Intel.

Actually Scott I reinstalled following your directions and everything worked. Thanks!!!

Caveat, the ethernet port only worked properly when connected to a 2.5GB switch. When connected to a Netgear 1GB switch it went back to the 10/10 behavior and was very erratic and made the entire network act strangely. Fortunately for me I have a 2.5GB switch.
