Proxy @ work, no proxy @ home I own a MacBookAir and surf great from home (wi-fi with WPA2).
From time to time, I'd want to bring it at work where I have a connection through proxy (i know address and port).
If I do save the settings when I am at work, will I have to reopen settings page and remove proxy setting when reconnecting from home?
You can configure two locations in your network settings and then configure the proxy for your work location in the advanced settings.
