I really like the idea behind ZeroShell but, so far, I failed in implementing it.
First round: I tried to implement ZeroShell on a desktop PC with a D-Link DWA-547 but that was not recognized by the MadWifi driver as being Atheros based.
Second round: I tried to implement ZeroShell on an Acer Aspire One A110L (which I think would be a real killer app) but its Wifi adapter was not recognized (maybe that’s because the adapter is PCI-Express connected?).
As for the second attempt, I think having ZeroShell installed on the Micro SD inside my Huawei E169 and booting the AAO from it would bring the best UMTS router solution out there (even battery backed-up!), so please, community, brainstorm and come out with some great ideas!
