I have my modem in the middle of house, but the wifi signal is very hit and miss outside in our shed (probably about 20metres away from the modem). So I was reading up on Wifi Boosters /Extenders and wondered if these units work and if you do use one did you notice a considerable improvement ? I called my local computer shop and they said either that or buy a new modem.
This is the one I was looking at which seems to be a good price.
