Hi guys, once again... Me.....
I'm wandering if BCM43xx actually does support for virtual AP,
What i mean for VAP is to bradcast more than one SSID being in AP mode or
AdHoc mode
For example: PUBLIC_SSID for those who want to connect to the AP and
PRIVATE_SSID (for
nodes links with Encryption)
According to dd-wrt it does actually support.
I've tried showing the SSID of one of them and hidding the other one but i
only see and
Can connect just with one.
Is about driver issues?, am i doing something wrong?
Thanks again.-

I've tried something similar with 2 mesh interfaces. However, only one
can be brought up at a time. Bringing up the second interface yields a
"SIOCSIFFLAGS: Operation not supported". It's probably the test at the
beginning of b43_op_add_interface. I haven't any idea what's involved in
removing that restriction.
The firmware doesn't support that, out of the box. So we return
-EOPNOTSUPP
I ran the following experiment on the 2.4 openwrt kamikaze on a Buffalo
hp-g54 (bcm5352).
I was able to connect to either VAP with my laptop running XP, dhcp gave
me an address, etc. and all worked.
This seems to be the same v4 firmware used by b43. Is this more a
reverse engineering issue than firmware?

Comments:
Initially both interfaces came up with OpenWrt2 as the ssid, but with
unique bssid's. I manually changed wl0 to OpenWrt1 using iwconfig.
Probably a pilot error or bug, but not significant to the experiment.
/etc/config/wireless:
config wifi-device wl0
option type broadcom
option channel 6
config wifi-iface
option device wl0
option network lan
option mode ap
option ssid OpenWrt1
option encryption none
config wifi-iface
option device wl0
option network lan
option mode ap
option ssid OpenWrt2
option encryption none
iwconfig output - note the unique bssid's
