wmwlmon is a wmdockapp which shows the state of a wireless network interface. In the title you see the network interface name and a led showing if the interface link is active. As next you see the signal strength from the conntected access point in dB (decibel). The bar shows the signal strength in percents. If the bar is full, it means that you have the full throughput of the bandwidth displayed in Mbps. As next you see the channel number. A red lock shines if WEP is enabled. The last line shows the network id.
A newer version may be available in the Window Maker dockapps git repository:
git clone https://repo.or.cz/dockapps.git
