nosedive52 well you got a couple of options, 1) if you got an old wireless router, you could have that down the garden if you got a shed to put it in then run an ethernet cable from one router to the other. They're tutorials online to turn old router into a wireless access point, that's what I did. 2) You could get a wireless repeater but don't think that will help if it's an old house, cable is king lol. Option 3 bare with me as I can't remember what they are called but you can get plugs for you electric socket to feed the network through, 1 goes in the house and the other in the socket down the garden similar to option 1 but without the long ethernet cable. Hope this helps, not great at explaining lol
