I'm trying to setup multiple ssids (two ap) and this is the error I get

root@OpenWrt:~# wifi up
Configuration file: /var/run/hostapd-ath0.conf
wlanconfig: ioctl: No such device
enable_atheros(wifi1): Failed to set up ap vif

Some (maybe?) useful info;

definitely using atheros AR5212

I'm building revision 11349 (did a make distclean just before) and will try it tomorrow.

Meanwhile, does anyone have any ideas of what the solution may be?

should be

wifi-device' 'wifi0'

I was almost replying to the other post

I've already tried wireless config with just one wifi-device block (thus only wifi0) and two wifi-iface blocks. Didn't work, the error message I got was the same as posted (but with wifi1 changed to wifi0 of course).

Did you manage to have two ssids?

ONLY when loading ath_pci into the kernel with the following parameters:

ath_pci autocreate=none maxvaps=2

(max is 32 for current openwrt's madwifi revision as given by http://madwifi.org/ticket/1769)

and with /etc/config/wireless like this:

config 'wifi-device' 'wifi0'
        option 'type' 'atheros'
        option 'channel' '11'
        option 'disabled' '0'

        option 'diversity' '0'
        option 'txantenna' '1'
        option 'rxantenna' '1'

config 'wifi-iface'
        option 'device' 'wifi0'
        option 'network' 'lan'
        option 'mode' 'ap'
        option 'ssid' 'OpenWrt1'
        option 'encryption' 'psk2'
        option 'hidden' '0'
        option 'isolate' '0'
        option 'txpower' '19'
        option 'bgscan' '0'
        option 'wds' '0'
        option 'key' 'one big fat secret 1'
        option '80211h' '0'
        option 'bursting' '1'

        option 'xr' '1'
        option 'ar' '0'
        option 'turbo' '0'
        option 'macpolicy' 'none'


config 'wifi-iface'
        option 'device' 'wifi0'
        option 'network' 'lan'
        option 'mode' 'ap'
        option 'ssid' 'OpenWrt1'
        option 'encryption' 'psk2'
        option 'hidden' '0'
        option 'isolate' '0'
        option 'txpower' '19'

        option 'xr' '1'
        option 'ar' '0'
        option 'turbo' '0'
        option 'macpolicy' 'none'

I was able to have two different SSIDs.

But...there are still some problems though...when I disable and enable the wifi interface more than (maxvaps-1) I have the following error:

root@OpenWrt:~# wifi down; sleep 1; wifi up
wlanconfig: ioctl: Input/output error
enable_atheros(wifi0): Failed to set up sta vif

        option 'mode' 'sta'
        option 'ssid' 'Wireless Ville de Lausanne'
        option 'encryption' 'none'

Does anyone of you guys have any idea of what's going on?

At this post http://forum.openwrt.org/viewtopic.php?pid=69252 Wallace78 is also having the same issue.

Could someone post a hint/direction on what the cause/solution could be?
Anyone running an updated version of madwifi?

The script network-wlan.sh from Webif uses none as the value of the
network option in /etc/config/wireless when the wifi-iface is not
supposed to be bridged.
This patch modifies madwifi.sh in order to take into account that possibility.
