I live in the UK and I used to get my Internet access from British Telecom, until it was taken over by EE. I access the Internet via wi-fi, which is provided by a network of cellphone transmitter masts. The problem is, I'm on the very fringe of the transmission area for the nearest mast, which means that I get logged out every half hour or so. Obviously, there's no way of getting nearer to the transmitter or boosting its signal, but is there any device I can attach to my Samsung tablet and my laptop to make them more sensitive to the signal?
