Safely connect two computers via P2P
Nowadays, there's usually a wireless network close by wherever you are if you need to connect your Mac to the net. AirRadar is an application which will allow you to scan for and connect to wireless networks nearby.
AirRadar easy to work with. A new Network Scanner helps you find the best networks in your area. Select the scanner option, then press the Start Scan button. Networks will start popping up in your list or you can also use the search box if you know the name of a network and it has a hidden name.
You can create your own list of favorites, or filter out those that you don't want to see. Unfortunately however, AirRadar doesn't allow you to drag and drop networks from the scanner tab to either favorites or filter. You'll have to enter them individually every time.
The graph section is fairly basic and will display both signal and noise levels. You can use it to monitor which network to connect to based on performances.
AirRadar is a basic but effective wireless network scanner and a solid alternative to OS X's Airport scanner..
