I am buying my wife a garden studio for her hobbies and I need to make sure she has a decent network connection for her laptop, its going to be about 10 meters from the WiFi repeater so the connection is not great and only just maintains connection integrity, I was looking into a Powerline solution but research indicates that adapters on different ring mains can be a problem, the main router is upstairs and the power supply to the studio will be taken off a spur in the garage. What are your experiences and do you have any recommendations as there are a bewildering array of products out there.
I have tried a high gain USB WiFi adapter with little improvement, although it was only an Edimax 3db gain model, I could try a box intended for caravans etc. if push came to shove.
Any help would be gratefully received before I part with precious funds.
