At the point where you realise the sw + fw + hw package you bought doesn't do what it is supposed to I'd say you should strongly consider returning it; if for nothing else then to teach them a lesson :-/
I specifically bought hardware with open WiFi driver and well compatible with open OSes, to be able to replace the stock installation. Why should I return it now?
Ok, I'm talking about the general "you", the public, not "shmerl".
You might be able to do that. Troy Hunt doesn't want to. I don't want to. If I want to be able to inspect my network gear I guess I should go with Microtik or something but to each their own.
