I have a number of variants of Lenny on different SD cards, but I have a problem connecting reliably with my router because the "clone devices" all have the same mac address.
Speculation/ Although I would never be able to run two clones at the same time, I suspect the router gets in a state about who has the lease on a given IP address/
I have no area of conflict between router/my pc/skytone, only between clones.
The mac address of the default OS starts 00:21:4D which I have positively ID'd to Skytone.
The mac address of all my Lennys starts 00:ef:a3.
I have not managed to change it persistently with macchanger, and the card that I tried to change by hand stopped working!
