I want to buy a Wifi Dongle that, besides acting as an ordinary Wifi client, could change its mode to work as an Access Point too. Should I buy a dongle with SoftAP or should I buy one with Wifi-Direct ? What is the difference between these 2 concepts ? Or is there any difference between them ?

Moreover, what chipset (Realtek, Ralink etc) could provide such a functionality ? Which chipset that has this functionality could work happily in a Debian/Ubuntu 32 bit environment ?

Thanks in advance for any suggestion.
