Wi-fi signal is very much dependent on the distance from the computer to router, and of course, the type of obstructions in between (such as thick brick walls).

One of the most efficient ways of extending the range of a wireless network is to use a wireless extender. This can increase the range of the router's signal up to 50 yards. This extender works by taking the wi-fi signal from the original router and rebroadcasting it from its location.

You can get one for £49.99 (saving £20) from Maplin.co.uk (click here).
