Onboard i225-V network controller not working properly
I ordered a wonderful LattePanda Sigma with 32 GB und was very happy in configuring the installation of Windows 11 Pro.
But then I noticed a known Problem with the onboard Intel i225-V network controllers.
The problem is, that both network ports won't connect to a normal GBit-Switch.
I already tried all advices I found. The BIOS of the Sigma is the newest found here, tried different Intel drivers and also tried different settings like forcing the auto-negotiation to 1 GBIT Full-Duplex. But nothing worked.
In the first minutes of the NICs don't detect the connected network-cable, after this I may have luck, if they negotiated with 10 MBit/s.
Here are the articles from Intel:
I'm wondering about nobody else posted this problem here.
So, did i miss a known solution?
