Windows 7 Wireless – great gadget for indicating network connection. As you may have guessed from the name – will work fine with the Windows 7 operating system. The app shows the status of the network connection as a percentage and using a special scale. If the signal is good-all the graduations will be highlighted green, if the bad – one or two counts. If there is no connection at all – on the scale will be the image of a red prohibition sign.
