Hello all, I've spend most of the last couple of days investigating the process of (trying to) work out which combination of hardware and software is required to create multiple interfaces (ssids) with a single WiFi harware device.... and I have reached the point where I need to ask some questions. I've looked at the Drivers page here:- http://linuxwireless.org/en/users/Drivers But it's not clear to me which column/if this table details if the device is capable of running multiple VIF's... and I'm not quite sure if the configuration I'm doing is correct. I've tried 2 different types of Ralink/Edimax dongle as well as the Centrino device in my laptop, and the ultimate goal is to be able to run both "batman advanced" as well as a standard WiFi client... or "batman advanced" as well as a WiFi AP. I'm getting stumped right at the outset.... because I can configure both interfaces, but if I try to bring 2 up at the same time with "ifconfig" I get "Device or resource busy". Here's what I'm trying to do, using kernel (Linux xwing 3.5.0-8-generic #8-Ubuntu SMP)... #iw phy phy0 interface add ah0 type ibss #ifconfig ah0 mtu 1528 #iwconfig ah0 mode ad-hoc essid batman-adv ap any channel 3 #ifconfig ah0 up This returns :- SIOCSIFFLAGS: Device or resource busy when I try to bring the interface up. If I first take the existing wlan0 interface down, I can bring ah0 up... and visa versa... but not at the same time... Is this a reasonable approach, I'm not sure if it's what I'm doing of if the driver isn't able to do what I want... and I can't seem to work out how to tell if multiple ssid's are supported by the driver or not. I hope this question isn't too simple, or answered in the documentation as I've spent a long time reading the documentation, and filtering out the old information such as madwifi etc... and I think I've got to the point where I have the correct process, but I'm left a bit stumped TBH. -- A.
