This seems backwards, but I cannot connect to open wireless networks, only WPA secure ones. I know this has worked in earlier TC versions (I am at 3.3 now). Doesn't matter if I try the wicd solution or just manually loading modules/firmware and iwconfig commands. I can connect to my WPA network, but not to "open" networks that require no authentication or security keys.
TinyCoreLinux 3.3
Broadcom b43 firmware loaded and works fine for WPA networks.
