Re: Changing the MAC address on a LAN adapter
Is this a known problem? As far as I know, it's supposed to work. Well, if it does not work it can be driver bug. Well, yes, that's what I'm asking. Is it a known driver bug? In iwn case try to set MAC address of iwn before creating wlan or you will need to set same MAC on wlanX and iwn. Done that, doesn't help.

Yes, although folks can set the locally administered bit in the 6-byte MAC address instead of using globally administered addresses vendor-assigned blocks from IEEE OUI...

Best regards, Fred Yes, but for lagg to work both adapters need the same MAC- otherwise routing wouldn't work properly (long story short).
