Hi,
Raspberry Pi Model B+, Linux blue 3.12.28+ #709 PREEMPT Mon Sep 8 15:28:00
BST 2014 armv6l GNU/Linux, hostapd v2.3 (defconfig), Ralink using rt2800usb
driver on either a Wi-Pi or Panda Ultra Wireless N USB Adapter.
What I'm trying to accomplish is using a single interface to be an AP on
one SSID, and ad-hoc on another SSID. The problem is that I can either do
one, or the other, but not both...
root@blue:~# iwconfig wlan1
wlan1 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:on
So if I set up ad-hoc, works fine :
root@blue:~# iw dev wlan1 interface add wlan10 type ibss
root@blue:~# iwconfig wlan10
wlan10 IEEE 802.11bgn ESSID:off/any
Mode:Ad-Hoc Cell: Not-Associated Tx-Power=0 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:on
root@blue:~# iwconfig wlan10 essid WEDDING
root@blue:~# ifconfig wlan10 10.4.4.8 netmask 255.255.255.0
root@blue:~# ping -c2 new

rtt min/avg/max/mdev = 1.024/2.268/3.512/1.244 ms
Now invoke hostapd with the following /etc/hostapd/hostapd.conf :
root@blue:~# cat /etc/hostapd/hostapd.conf
interface=wlan1
ssid=FREE
hw_mode=g
channel=1
root@blue:~# /usr/local/bin/hostapd -dd /etc/hostapd/hostapd.conf
(Please see http://pastebin.com/cjqukwyH)
But if I reboot and try backwards :
root@blue:~# hostapd -dd /etc/hostapd/hostapd.conf
(Please see http://pastebin.com/Tdc5dz81)
And its fine, but then :
root@blue:~# iw dev wlan1 interface add wlan10 type ibss
root@blue:~# iwconfig wlan10
wlan10 IEEE 802.11bgn ESSID:off/any

Any idea where to look or what to do to get them to work and play together?
I am not an expert, but this sounds like a proper application of virtual interfaces.
