6 I210 NICs with same MAC address... Please help

Toxic

Hello,

Sorry, wrong channel, I will repost in a more appropriate, it's not an intel core issue... intel 210

I'm usually a normal general customer, tech-savvy, but general public.

I have a i5-8365U computer with 6 integrated I210 NICs, but somehow at the factory they made a mistake when programming the NICs and they all have the same MAC address ! You can imagine the hassle when trying to use more than one NIC at a time.. The chinese seller is not responding anymore, and now I'm stuck with trying to re-write the MAC address.

I see that I would need nvmupdate for i210 and that is usually reserved for priviledged accounts...

Maybe you have another way to help me ?

Or do I need to register for a priviledged account and try to guess at what the settings should be ?

I already found sometime ago an unofficial version of nvmupdate that I was able to run because I had "NVM checksum is invalid" issues, but that's not the proper route I think, maybe you can help me find some random 6 MAC adressses and the tooling to be able to assign them to my NICs...

Here is a comy of ipconfig in windows to clearly see that all MACs are the same :

Definitely a "third party company" ! I'm your average joe, not designing or building boards

I guess "noname" is the closest thing... I got the device from aliexpresse, it's this one :

https://fr.aliexpress.com/item/4001183180654.html?spm=a2g0s.12269583.0.0.5b305b2cwZvEAE

Could you please list the source used to design your affected design? 

Sadly, I have no informatin on this, sorry

Could you please let us know the Operating Systems related to the reported situation?

I'm using Windows 10 Pro

I encounter the same issue with linux (Ubuntu 20.04).

 

I don't know the hardware detail, but somehow the OS queries each NIC for it's MAC address, and my 6 NICs have been somehow mssconfigured to report the same MAC...

 

Hope this can help you help me, sorry I can't be of more help, I do feel I'm a simple consumer in a forum dedicated to hardware designers... Bu when it's firmware issues like this I don't know where to turn to with the seller not responding...

I understand that this is the proper way.

But after several messages, I am still a bit disappointed that there isn't a way to just get a tool to rewrite that MAC address, I'm pretty sure that is possible and even if I understand an I210 NIC can be customized by the manufacturer, I feel that with most instances of I210 in the wild, a tool able to rewrite the MAC is quite likely gonna be working on more than 80% of them... I'd be willing to give it a shot, I'd even be willing to sign a non-disclosure agreement or whatever, but it seems you're not willing to share the tool or give a shot at helping the end customers that come here because of poor support of your resellers...

You're still happy to sell them chips, but not help support... better to send me waiting months waiting for them and hoping that they understand my problem, which I doubt, seeing the broken english with which theiy respond at the break-neck pace of one message per week...

I have no contract with Intel, that's the game, I understand it, just a bit disappointed nonetheless...
