Virtual Interfaces with iwlwifi

Virtual Interfaces with iwlwifi

[Risse Kilian]

Hi

I tried to create a second interface and connect to another AP. But I was unable to do so. As I tried to enable the second interface I got an error: Device or resource busy. So am I right assuming that this is not possible with the iwlwifi driver?

Thanks

Kilian

What specific hardware do you have?
What kernel version do you have?
What specific command were you using to create the second interface?
What are the "software interface modes" and "valid interface
combinations" sections output from "iw phy0 info"?

It's certainly possible and supported with iwlwifi, but it depends on
specific hardware, the driver, etc.

I think I figured it out - I tried to create two interfaces of the same 
type station - which is not supported according to the "iw phy0 info".

I use a intel 7260 card with a 3.18.7 Kernel.
The command I used was "iw phy phy0 interface add wlan0 type station".
Is this a limitation in hardware or software?

firmware which pretty much means hardware ;)
You can have BSS and P2P client though.
