The ZyXEL AG-225H WiFi Finder has a name much larger than the device but it’s fitting since the device does so much. Finding WiFi hotspots is just the beginning when you are using the WiFi Finder because it is also a full featured access point so you can plug into a wired ethernet network and share it via WiFi with others nearby. The little AP detects 802.11 a/b/g and pre-N networks and provides detailed information and displays SSID, signal strength and security information about the hotspot. This is the first device I have seen that combines wireless AP and WiFi detector in one unit making it the perfect travel companion. The LiON battery means you can use it without a power outlet for the ultimate portable experience. $99.
