The Phicom deal I posted has now rocketed 50% in price, but this is even cheaper, by a pound, for much the same functionality- Wireless Mode Access Point, Router, Repeater, Bridge and Client. Nevertheless, there will be at least three posters who claim that is must be useless because they can't think of why they would want to use it in one of these ways. The main difference between this and the now more expensive Phicom or TPLink units is that it doesn't plug straight into a socket. It is powered by a USB power supply (not supplied, you only get the cable), which may be more convenient when travelling abroad. It will even run on a car USB charger!
