AirRadar is a program that might come in handy while traveling. It can help you immediately find the Wi-Fi networks in your area and easily connect to the networks with the best download and upload speeds.
The utility features a straightforward interface, provides you with accurate information, and comes with a fair price. You can always start and stop the scanning process, save the scan results for later, and mark your favorite networks.
Furthermore, unlike many of its competitors, AirRadar provides you with a quick and simple way to connect to the found Wi-Fi networks directly from its interface. You can also disconnect from networks, attach notes to identify them later, and remove Wi-Fi networks from the given list if needed.
The only problem I had was that the utility took a while to launch. Another thing you need to consider is that you can find a cheaper solution. Still, they aren't as feature-rich and efficient as AirRadar.
All in all, AirRadar is a helpful Mac program that helps you immediately identify nearby Wi-Fi networks. I'd say it's worth a try.
