There's no denying the usefulness of Wi-Fi, especially when you're out and about and need a fast internet connection. Finding a hotspot, however, can be a hit-and-miss affair. You either have to wander around with your laptop on, waiting until it finds a network, or ask around.
But with Trendnet's snappily titled TEW-429UB – which combines a Wi-Fi USB adapter with a hotspot detector – those days are gone. To find an available network, simply switch it on, press the seek button and wait a few seconds. It'll scan the area and bring back a list of available networks, including whether the networks are encrypted or not, which is a useful feature.
Once you've found a suitable network, boot up your laptop, plug the TEW-429UB into a spare USB port and surf away.
Unfortunately the Trendnet is let down on the software side – the supplied utility for configuring the device is quite temperamental.
