I've read that it is possible to alter your MAC address with the following command, so I tried it with my D-Link DCF-650W card (SL5500 with SharpRom 2.38):
ifconfig eth0 hw ether 00:00:00:00:00:00
Didn't work. Returned:
SIOCSIFHWADDR: Device or resource busy
So I thought:
ifconfig eth0 down
ifconfig eth0 hw ether 00:00...
ifconfig eth0 up
No. So:
ifconfig eth0 down
ifconfig eth0 hw ether 00:00... up
Well, you get the idea. I also tried editting /etc/pcmcia/network; changing the HWADDR=`whatever ...` to HWADDR="00:00:00:...", but that didn't work either.
Maybe my drivers can't handle it, but I don't know how to diagnose that. I'd welcome advice. Has anyone got this card? Have you ever changed your MAC? Thanks.
