If you want your friends to think you’re a cheap bastard (and you know you are) and want to give your laptop the WiFi capabilities it so desperately needs, Ublog has a step-by-step DIY tutorial to make a simple and cheap Yagi antenna. Who would’ve though a piece of wood and a series of rods were all the components you need for some hot wireless action.
The antenna is a retro-looking thing, so finding the right direction to point it towards for it to work effectively could pose some problems. If you’re still not getting a signal, wrap it in aluminum foil. Unlike other antennae, you’ll have WiFi but you’ll still feel like you’re adjusting the antenna of a ’60’s TV.
