WiFi-Tracker

Wi-Fi Tracker is a tiny widget that allows you to keep track of your wireless network status, directly from the desktop. It can be seamlessly installed and set up, even by inexperienced users.
The interface of the application is represented by a small frame whose position you can change to any spot on the desktop, with the help of the mouse cursor; it displays the current WiFi signal.
By accessing the Widget Preferences area from the right-click menu, you can set up your WiFi-Tracker.com username and password, in order to get network information reporting. However, this is not a mandatory option.
With the courtesy of Yahoo! Widget Engine, you may also make the window stay on top or below all the other frames, ignore mouse events and prevent dragging. Last but not least, you can adjust its opacity level between 20% and 100%.
The simple-to-use widget has a good response time and runs on a very low amount of CPU and system memory, so it does not interfere with the runtime of active processes. No error dialogs have been shown in our tests and Wi-Fi Tracker did not hang or crash. Thanks to its intuitive layout and overall simplicity, first-time users can seamlessly figure out how to work with Wi-Fi Tracker.
