I need to setup my mac as wifi-router. I want it to appear indistinguishable from a stand alone wifi-router. I don't want internet access.
Things I've tried.
Turning on Internet Sharing
Doesn't work AFAICT. Probably because I have no internet to share. I was hoping turning it on and picking something to share even if it's not connected to the internet would still make an SSID appear for other machines to connect but no such luck.
Pick "Create Network..." from the network menu
This gets an SSID to show up for other devices, specifically iOS. Unfortunately there is something special about them as they show up under a special "devices" section below the list of normal wifi hotspots. That's something I'm specifically trying to avoid.
I've noticed in Linux apparently a set of tools,
iwconfig etc.. deal with this kind of stuff but I haven't found the equivalent on OSX.
