This is a widget I wrote called "WirelessSignal" and is designed to represent a WiFi card's signal strength in bars. The "rings" idea was adopted from Justin Pulsipher's "System Dashboard - Wireless Meter".
WirelessSignal - Preview |
The widget is tested on Windows XP, Window 7, Ubuntu 10.04 (should work on Mac with some small changes).
How is WirelessSignal percentage determined?
- The signal on XP is determined by a vbscript "signal_xp.vbs", which returns the -dBm signal of the first detected wireless card. Then the -dBm is run through a linear conversion to determine percentage.
- The signal on Windows 7 is determined by the command "netsh wlan show interfaces", which calculates and returns its own percentage.
- The signal on Ubuntu is determined by calling the command "/sbin/iwconfig", then using the same linear conversion as XP.
- The signal on OS X is determined by calling the command "/System/Library/... .../Resources/airport", then using the same linear conversion as XP.
- On Windows XP, due to the resources needed to call "cscript.exe", the widget spikes at about 9%. Recommendations to fix this are welcome. The update frequency can be tweaked to minimize system impact.
- 2 display styles: Rings or Bars
- 5 size options: Tiny, Small, Medium, Large, Huge
- Custom font color, custom font size
- Simulation/demonstration mode
- Update interval in milliseconds, i.e. 2500
What license is the SVG artwork released under?
How do I install WirelessSignal?
- Download and install version 0.9.9 (or higher) of the Kludget Widget Framework from http://www.kludgets.com/download
- Run the Kludget framework.
- If you receive an error message “kludgets engine failed to start”, make sure the latest Visual C++ Runtime is installed from http://www.microsoft.com/downloads/details.aspx?FamilyID=9b2da534-3e03-4391-8a4d-074b9f2bc1bf
- Right click the Kludget icon in the system tray, Open Widget Package.
- Browse to WirelessSignal.zip and click open. (widget zip file available upon request)
- If WirelessSignal.zip is named “WirelssSignal_2.0.0.zip”, rename to “WirelessSignal.zip” before opening. It will not work with the incorrect name.
