I usually use two wireless networks, my home and university, to browse Internet.

In my university I have been assigned a specific IP address and connect to the Internet through a proxy server where as at home I simply let my router assign me settings via DHCP. On a Mac, it is really easy to make a profile for a specific network rather than input the settings manually every time (Windows eh..) we are in a different network. We can make as many network profiles as we need to and assign the network settings in them. So whenever you go to the particular location, just select the profile from the network preference pane. It’s that simple!

Let’s see how:

Select the ‘Network’ pane from System Preferences.

In the ‘Locations’ drop down menu, select the option ‘Edit Locations’.

Then Click on the little + symbol and type in the location’s name.

Now click on the ‘Advanced’ button and the settings for Airport pop up. In the TCP/IP section enter your IP address and Subnet Mask.

Enter the Domain Name Server address in the DNS section.

If you network uses proxies to browse Internet, change those settings in the ‘Proxies’ tab.

Click Ok and then Apply. Next time whenever you want to switch network location, just select it from the locations menu in the Network preference pane.
