Wireless Networking Problem

[TheBuzz]

I am trying to set up a wireless network between my home computers to play lan games. I have a DLINK DI-824VUP+ which has a small inbuilt antenna. I am trying to network with a computer downstairs but the floor is 8inch thick concrete and I cant get a signal. The guys at ?Computers Online are suggesting I use two directional antennas but before I buy them I want to know if they will actually work. Can anyone tell me from experience if this is going to solve my problem?

While the directional antennas will boost signal range and receive sensitivity, it also depends on the transmission power of 1) the router and 2) the wireless adapter in computer no. 2. If you got two ~14 dBi directional antennas and pointed them at each other, I'd guess it would work over that range. But every situation is different and the only way to know for sure is to try. If it doesn't work, just post a thread in the For Sale/Trade category.
