Hi,

 

I have set up my iMac for NAT via AirPort so it becomes a wireless router.

I am looking for a way to turn off SSID broadcasting but the GUI setting (Preferences -> Sharing -> Internet Sharing) doesn't seem to have an option for it.

 

After some poking around, I was able to read the manpage on InternetSharing which pointed to the file

/Library/Preferences/SystemConfiguration/com.apple.nat.plist

for changing anything manually.

 

I have also read the following discussion, which apparently was back in 2007 ...

https://discussions.apple.com/message/4220509

... and now I am confused.

I have used other routers before with hidden SSIDs where any devices connecting to one needed to enter the SSID manually, without my neighbors knowing about it.

 

Questions:

Is this still a bad idea (as answered on message 4220509)?

Has anything changed from 2007, with some key that I can add to com.apple.nat.plist to disable SSID broadcasting?  Any idea how to edit it?

 

Thanks in advance for any help.

    1st) the WiFi NAT router offered by your Snow Leopard iMac use WEP security, which can be cracked in under a minute.

     

    2nd) hiding your SSID on a WEP encrypted router will not give you any additional protection.

     

    You should really get a standalone WiFi router and use WPA2 encryption (you can get really cheap ones that offer more protection that your iMac with WEP encryption).  While I wouldn't bother hiding the SSID, at least a regular WiFi router will make that option easily available (it doesn't really add to your security, but it is easier to set).
