nuc7i7bnh ethernet hangs on ubuntu

Hi,

I've just installed a new NUC 7i7BNH with ubuntu 18.04 (first installation of this NUC...) and the ethernet port hangs (drop packets ?) very often. I can see it when pinging the router where the NUC is connected to (loosing more than 35% packets over an hour). I've changed the cable/switch port but the issue is still here.

I think the bios is the last one :

Here is the information:

Intel desktop board : NUC7i7BNB

Bios version : nbkbl357.86A.0066.0724.1832

processor : Intel(r) code(tm) i7-7567U cpu @ 3.50GHz

installed with 32G RAM + 2 SSD (one sata, one M2)

Any idea ? Software ? Hardware ?

Hello rejo

 

 

Thank you for joining the community.

 

 

I see that you are having problems with the Ethernet connection using Intel® NUC Kit NUC7i7BNH. Allow me to help with your inquiries.

 

 

I would suggest testing the Intel® NUC with a different operating system upon reviewing the supported operating system for the Intel® NUC is Windows® 10 64 bit (https://www.intel.com/content/www/us/en/support/articles/000005628/mini-pcs.html https://www.intel.com/content/www/us/en/support/articles/000005628/mini-pcs.html). Also, you could try contacting the UBUNTU communities (https://www.ubuntu.com/community https://www.ubuntu.com/community) for a possible driver update

 

 

Hope his help.

 

 

Regards,

Hello Leonardo,

Thanks for your answer.

Sorry but I had little time to test further.

I checked all the litterature I could find about about NUC and linux and did not find anything about some ethernet problem.

I also tried with wifi and everything works well.

I also have a NUC of a previous generation runnning on linux with no problem. So I'll check again the connection next week end.

Ok, the issue was coming from the switch.

It is quite old and it seems to have an internal failure when connecting to ports 5 to 8 (loss of packets when going from ports (1 to 4) to ports (5-8)...

So regarding the NUC, the problem is fixed.
