I want to extend the wifi reach in my house..
Whats the best product I should be buying to do this? Right now I'm using the standard plusnet router in my bedroom and every other room in the house has not so good wifi reception. I only get about 50mb download speed from fibre plus.. 
Should I be buying an entirely new router or should I be buying those wifi extender plug thingies? Can anyone recommend a good one? Thanks.
