Find a wireless Hot Spot without the need of a computer. Just push the button on the Keyring WiFi Detector and the LEDs light up when it senses an 802.11b or 802.11g network. The more lights the higher the signal strength.
The WiFi Detector is designed to find Hot Spots at the same range as most Wireless Network Cards. It is also capable of distinguishing between the 802.11b/g wireless network and other devices that use the 2.4GHz radio band, only lighting up when the 802.11b/g wireless network is detected.
