Positioning orange livebox
I'm getting wireless broadband through an Orange livebox but need the signal to extend to a workshed at the bottom of my garden.The sheds within range but there's a wall partly in the way.I seem to get a worse signal if the livebox is upstairs in the house-even though that's higher than the wall.Does anyone know where an optimum position would be,for instance does it need to be up close to a window or a certain distance from it and is the range better if the origin (livebox) is low or high.
Any advice would be appreciated as orange don't seem to know.Thankyou
