Dear Sirs,
I have a pc with an Intel Card, Intel Corporation Centrino
Advanced-N 6235 [8086:088e] (rev 24), driven by iwlwifi. I
have installed the backports version of iwlwifi.
The card and the driver work flawlessly. I am having troubles,
though, when I try two build two virtual interfaces on this
card, one in Station mode and the other in AP mode.
The output of iw list states, among other things, that:
Supported interface modes:
│
* IBSS
* managed
* AP
* AP/VLAN
* monitor
* P2P-client
* P2P-GO
software interface modes (can always be added):
* AP/VLAN
* monitor
valid interface combinations:
* #{ managed } <= 1, #{ AP, P2P-GO } <= 1,
total <= 2, #channels <= 1, STA/AP BI must
match
* #{ managed } <= 2, #{ P2P-client } <= 1,
total <= 2, #channels <= 1
I have interpreted this to mean that I can put my card into AP
mode (I did, it works). The "valid interface combinations"
appeared to state (if I read them right) that I can have at
most one vif in station mode, 1 vif in AP mode, for a grand
total of two, provided that they are on the same channel, and
provided that
STA/AP BI must match
What does this mean? I have been unable to find this on
Google, and several posts at moderately knowledgeable BBs like
SuperUser, StackOverflow and the like have provided no
enlightenment.
Since clients connecting to my AP are so far unable to obtain
an IP address from my network, I am wondering whether this
requirement, whose meaning I completely ignore, is the source
of the problem.
Do you think you can help me out on this one?
Cheers,
Mario
