I found a solution and it is working from the top floor to my basement although it is not so strong in my basement. I turned off the wifi section of my Linksys and bought a EngeniusTech 3610S device to be used as a broadcaster. I connected a 16dbi yagi antenna to the 3610S moved it all around until I found the optimum location whereby I was getting the strongest signal in my basement and connected my TW cable to the Linksys and outputted the signal to the broadcaster and I am home free. This was a experience that took almost 2-3 months of experimenting but it works wherever one is in my house.
Hope this info helps
