</span>It depends on your hardware and driver whether this is possible. Look<br>
at the output of "iw phy phy0 info", where you should see stuff like:<br>
<br>
valid interface combinations:<br>
* #{ managed } <= 1, #{ AP } <= 1,<br>
total <= 2, #channels <= 1, STA/AP BI must match<br>
* #{ managed } <= 2,<br>
total <= 2, #channels <= 1<br>
<br>
These lines indicate what your hardware and driver can do at the same<br>
time. In this case (Intel 6250, iwldvm driver) I can do 1 AP + 1 STA,<br>
or 2 STA at the same time, but all must be on the same radio channel.<br>
