Basically we have wifi but our router is shit not performing as well as we'd like it to. According to the engineer that came round today our walls are too thick and we will need to get a repeater. OK fair anough. My computer will be in our barn conversionwhich is about 10 metres away from our house, and the wifi will need to stretch across the house - about 20 metres - so in total the range will need to be about 30 metres.
Can anyone recommend a really good repeater and will it extend to our outbuilding even though we have 'thick walls'?
Thanks in advance.
