Network locations does not save in Mountain Lion

Right as YOU ARE changing the WiFi network #1 is using.

While on location one open Network in Sys Prefs then click on the Location drop down and select Edit Locations. Hit the plus sign at the bottom and type in a name. Then click Done. Then select WiFi in the left hand panel and select the WiFi network name SSID you want to connect to, type in the password. Click Join.

EDIT:

Also click Apply at the bottom of that window after every operation.

Yeah I'm seeing that also. I'll have to boot back into Lion and check it there. That will be a few minutes.

EDIT:

I did notice that everytime I added a Location it defaulted to Ethernet.

Instead of using the Location section just click the WiFi icon and select your new SSID name you want to use. Once you type in the password for that new SSID it will be saved in the Advaanced section Preferred Networks area and you can switch back and forth at will from the WiFi Icon in the menu bar.

Well then I think you will need to set your locations for the proxies and then switch the WiFi to the other SSID for that proxi.

Looks like WiFi SSID name connections are independent of Location settings. I'm getting the same thing in Lion.

The ability to have different network settings for different locations went away in Lion, unfortunately.

When Lion first came out, I filed a bug with Apple about it. They said that it "Behaves correctly". At this point, I don't even understand why "Locations" still exist – the only thing they control is which network interfaces are active, not the settings assigned to those interfaces.

A real shame. The old location feature was very useful and worked very well – it allowed me to quickly change my list of preferred networks and DNS settings when I took my laptop on campus.
