Incorrect mac address on NIC


SnowDrifter

Recommended Posts

Declared the actual mac address of my NIC in the grub cfg

Network card works as expected otherwise. But mac address in network matches neither my config, nor the address printed on the card. A reboot of the machine will result in a different, seemingly randomly assigned mac address.

Jun 1.4b
have the extended driver pack
918+
Intel i3-9100
DSM 6.2.3 update 3
Intel X540-T2

Network interfaces were enabled in synoinf.conf and all 4 show up fine (2x onboard, 2x nic) within DSM. It's just this randomly assigned mac address issue I can't figure out

Mac addresses should not change the are hard coded to the nic if the nic in dsm some how get a new mac then we need te check configs and bios/efi of the system

It's assigned a new one on every boot. Something funky.

swapped a drive to a larger one so it's in limbo to 3-4 days but once that's done I'll check back in. Any notes on what I would be checking for in the bios? Asrock rack board if that's pertinent

Should be done later today then I can go digging. What all am I looking for?

On the boot drive (usb Flash drive)  u use to boot je bare metal system there is a floder called Grub in that folder you will find an grub.txt file that is the boot config synoboot usses to set things like usb flash pid and vid and nic macs 

please share that so we can see if the config file is the culprit of you mac issues

no mac3?

Dude.......

Couldn't tell you how many times I looked at that and missed the obvious. Yeeeesh. It's fixed and proper now.

Now if you'll excuse me I'm going to avoid eye contact and pretend this never happened.

Thanks for the second set of eyes
