Slow download with Intel® Ethernet Controller I226-V

Hi,

I have a new Intel NUC13ANKi5 with the Intel® Ethernet Controller I226-V. Everything is uptodate using the Intel® Driver- and Support-Assistant.

The download speed is too low, even lower than the upload speed.

I have 350-500 Mbit/s download speed with WiFi but only 29-38 Mbit/s with Ethernet Controller I226. Even the upoad is faster, with 50-60Mbit/s equal to the upload speed with WiFi.

Using the same Ethernet cable with other PC the download speed is 350-500Mbit/s. So it can't be a matter of the cable or router.

I did not change anything on the Ethernet Controller I226 settings. I removed it an installed it again but it did not help.

The Windows-Driver-Manager shows an error with "e2fnexpress" after installing the driver, nonetheless the properties windows states "The device is working properly."

Setting "Speed and Duplex" to "100MBit/s Fullduplex" the download speed rises to 98MBit/s. All other "Speed and Duplex"-settings result in much lower download speed: 9-38MBit/s.

I did everything what is suggested here:

What can I do to get normal download speed?

Not fixed for me. I updated BIOS to [ANRPL357] but the slow speed with Ethernet Controller I226-V remains if I turn off my workaround posted on September 23, 2023.
