I have re-built entire 7.0.2.1 release
Then the same issue exists, I have tried all builds on the v2.0 board and each one gives me a random MAC address each boot
As expected, the 'wrong' builds are also unable to switch the LED. ALL builds produce a random MAC address each reboot
I'll check again with the update builds
If it just turns out to be me, don't worry about it, as the script posted earlier does correct this problem
