We live in a new build property of timber frame construction. Every wall is installed with this silver faced insulation. The property is fairly small with a good sized rear garden. I'm constantly having problems getting the wifi to reach garden shed which is approx 20 metres away from the router. I initially blamed the poor Sky router so this time I've purchased the Linksys wrt3200acm. But still, despite its four alien looking antenna's have the same issue.
I guess Ideally moving the router to the upstairs bedroom may be the answer, but there is no adsl socket there plus all the other devices are routed to the living room where the router currently sits. Any suggestions, is there a way to amplify the signal to get more gain?
