Earlier this month I re-mashed top ten tips for improving your wireless network. But, one of the simplest, incredibly lo-tech things you can do, is to print out a template, glue some aluminum foil to some card, fold tab A into slot Z, and fit it to your router antenna for a major serious signal boost. In fact the guys in the video below got a 12 decibel (dB) signal boost, which was way over the boost they got with a $50 antenna, and not a soldering iron in sight.
If you want more info on how to improve your signal the cheap and cheerful way, check out Free Antennas site and look for the EZ-12 parabolic reflector template.
I’m just digging around my kids’ craft cupboard right now looking for a glue stick and some sheets of card.
