No joy yet.
I must be missing something somewhere.
I've changed the mac on the sb5100 three times,put a lite con fig file name in and can't obtain an ip address.
Watching it in networksettings it gets the 192.168.100.1 the blanks then goes 169.etc.
I know thats bad.
I read on posts at tcniso that changing some of the settings might work,like factory mode.
I got three surfboards and just put a ambit 120 mac on it without the sigma-x to see if it would connect?
I'm missing something somewhere but can't get it.
The forum on tcniso is shite,no real help on there.
I'll keep trying.
