Do you think is it possible to use the internal wifi chipset like AP and client at the same time??? I don't even know if is it possible in Linux...but I do it in windows 7 every day with applications like virtual router or connectify... is it possible to use the internal wifi chipset like AP and client at the same time? No. There are two different versions of the firmware, one for AP, one for Client, you choose which one to load and then you are stuck with it until a reboot. Quote I do it in windows 7 every day No you don't. AP Mode requires support in the WiFi device itself, it has nothing to do with Windows or Windows drivers. If you run the Guruplug in Client mode you can (obviously) connect to access points. It should also be possible to connect to other WiFi Clients (google Ad-Hoc Mode) providing they also support Ad-Hoc point-to-point.
