hostapd multiple SSIDs with one BSSID

I have a [wl12xx](https://en.wikipedia.org/wiki/Wl12xx) wifi adapter that unfortunately does not seem to support creating multiple access points. If I run iw list it outputs this line: interface combinations are not supported If I run hostapd with multiple SSIDs set up if sometimes runs, and sometimes gives me too many files are open, or device or resource busy. In any case I have only ever seen it make one wifi network. As I understand it, a BSSID is basically the wifi card's MAC address, and the standard way to create multiple APs with hostapd is to create multiple network interfaces, each with their own BSSID (MAC address) and SSID. It's as if you had multiple physical network cards. This mode appears to be not supported by my hardware but I actually only want one network (BSSID) with multiple SSIDs. Is it possible to do this? Does hostapd support it (there's very little documentation for it)? Does the wifi standard allow it? To put it in other words, instead of this: # First network on wlan0.ap1 interface=wlan0.ap1 ssid=my_first_ssid # Second network. bss=X starts a new section, using the network interface X. # I think that's how it works anyway. Documentation is very unclear and the config # file format is idiotic. bss=wlan0.ap2 ssid=my_second_ssid # Third network. bss=wlan0.ap3 ssid=my_third_ssid I want something like this. A single network that broadcasts itself as three SSIDs. # Single network on wlan0.ap1 with three ssids. interface=wlan0.ap1 ssid=my_first_ssid, my_second_ssid, my_third_ssid Or maybe something like this would work? interface=wlan0.ap1 ssid=my_first_ssid bss=wlan0.ap1 # Same interface ssid=my_second_ssid bss=wlan0.ap1 ssid=my_third_ssid Or this? interface=wlan0.ap1 ssid=my_first_ssid bssid=02:01:03:04:05:06 bss=wlan0.ap2 ssid=my_second_ssid bssid=02:01:03:04:05:06 # Same BSSID bss=wlan0.ap3 ssid=my_third_ssid bssid=02:01:03:04:05:06 Am I going to have to read the source code?
