I am trying to get a signal from the office in a detached Garage to the Main House. Using just a wireless router and a card (linksys G) I get a 20% signal that is not the best in the world. However, if I go downstairs and to the corner of the house I get about a 70% signal. So I would like to use wireless repeaters to move the signal across the house. I guestimate from the performance that I am getting from Garage to house, I will need three repeaters to get the signal to the far corner bedrooms. However when reading up on the DWL-G800AP I learn that throughput is halved each time it is repeater. What does that mean to performance and web usage?
