Comprei um adaptador sem fio USB Leoxsys para o meu laptop (Kubuntu 15.04) e instalei os drivers necessários. Ele pode detectar outros dispositivos Wi-Fi, mas não consigo criar um ponto de acesso usando-o.
O adaptador sem fio mostra a execução em -

Eu tentei criar o hotspot usando o ap-hotspot, mas ele diz:
$ sudo ./ap-hotspot start
Your wireless card or driver does not support Access Point mode
O adaptador sem fio não é mostrado em lspci , porque não está conectado ao barramento PCI. Pode ser mostrado em lsusb .
Nem todos os adaptadores sem fio podem ser usados como um ponto de acesso.
E você pode ver que "sua placa ou driver sem fio não suporta o modo Access Point".
