If for some reason your PC or laptop doesn’t come equipped with a wireless card then the Wi-Fi Detective is what you’ve been looking for. Maybe your parents or grandparents have an old ass computer that needs to get on the Net then look no further. The Wi-Fi Detective instantly picks up SSID, signal strength, network type (b/g), network mode (infrastructure or adhoc), operating channel and the number of access points in the area. You can also use it as a USB wireless LAN adapter with transfer rates up to 54Mbps protected by WEP, WPA and WPA2. The rechargeable battery is also a nice touch. The Wi-Fi Detective is compatible with Windows machines and is available now for $74.99.
