Open WiFi network shows up as secure on Mac OS X

My friend has a Netgear WGR614v8 wireless network with an SSID of "Mo's Place is Fun" setup as an open network. When a computer running Mac OS X sees the network, the Mac thinks that the network is actually secure and is unable to join the wireless network (I've tried a blank password with no luck). I have verified this with both 10.5 (Leopard) and 10.6 (Snow Leopard). I have been able to connect to this wireless network with Windows based computers as well as a variety of mobile devices (including the iPhone).

When I was running OS X 10.5 (Leopard), I could use MacStumbler to circumvent this issue and force OS X to connect to the network. However, with 10.6, I can no longer do this.

Has anyone else experienced an issue like this. More importantly, does anyone have a fix or workaround? I'm wondering if the issue is with the name of the network since it contains both spaces and an apostrophe. Any feedback is appreciated.

 

Sorry, but it is an open network. I can connect to the network without a password using a Windows computer and an iPhone. I have been able to use MacStumbler in the past to connect my OS X 10.5 to the network without a password.
