NUC12WSHi7 wired network speed stuck at 100mbit

[stjohn]

I bought an INTEL NUC12WSHi7 but only get 100mbit throughput of the wired ethernet in linux.

I have tried Ubuntu 20.04, Ubuntu 22.04, Debian 11 with several different kernels. Same result.

The nic is the 225-v rev 3.

There seems to be lot's of people having similar issues.

What should I do?

Hello stjohn,

Thank you for posting on the Intel® communities.

I am sorry you are having issues with your Intel® NUC 12 Pro Kit NUC12WSHi7, I will be glad to help you.

Please provide the following information:

• Have you installed the latest Ethernet driver 1.1.3.34 (https://www.intel.com/content/www/us/en/download/739770/intel-ethernet-lan-network-connection-driver-for-windows-10-64-bit-and-windows-11-for-intel-nuc12ws-products.html)?
• Have you tried with different Ethernet cables?
• Does it get stuck at 100 Mbps even when connected to a different network?
• How are you measuring the speed?

Hey!

• Have you installed the latest Ethernet driver 1.1.3.34 (https://www.intel.com/content/www/us/en/download/739770/intel-ethernet-lan-network-connection-driver...)? - Yes
• Have you tried with different Ethernet cables? - Yes, 4 different (all of them gives me 1gbit with other computers)
• Does it get stuck at 100 Mbps even when connected to a different network? - Yes, tried 2 different switches and 1 router.
• How are you measuring the speed? - Both by checking the link status on the switches/router and within the nuc itself as well as with different "speed"-services.
• I have also tried to force it to use 1gbit from both nuc side and switch/router side - making it lose link completely.

I have been in contact with Intel technical support via my reseller, he said it's probably a faulty card.

I'm now in contact with my reseller to get a new one - or if that fails, I'll contact Intel again.

Many thanks for your response.

Hi!

A new nuc from my reseller solved it. Moved disk and ram over and it worked immediately after booting.

1gbit stable connection.
