a friend of mine has a broadband modem connected to his older desktop set up in the office..he also has a wireless laptop that picks the signal no problem around the house.
But outside in the granny flat the signal is almost non existant due to the fact..i think that a heavy brick chimney is in direct line between the office and the granny flat..any suggestions in how to improve the signal apart from knocking the old thick chimney!!...the distance to the flat is no problem as the signal is quite strong a few metres outside the flat in the garden!!
