Trust releases budget WiFi network locator
If you want to find a WiFi network on the cheap (I’m still not convinced that that Pringle tin things works, dammit!) then you could do worse than the Trust WiFi hotspot finder (you may remember Trust as those enterprising bods who brought you that battery tester not so long back). The signal strength of the available WiFi network (both 802.11b and 802.11g) is shown with five LEDs on the front, allowing for a quick survey of potential internet access points without resorting to pulling your laptop out. The scanner has a 150m range and goes for £19.99.
