The Dish Network is diagnal from the router to the front left, and it is approxemently 25ft from the router with one wall. Laptop 1 is positioned directly to the front of the router, and it is no more than 10ft away. I'm worried that the beam will not be wide enough to hit the laptop infront of the router, and my Dish Network receiver that is positions diagnally to the front left. I have attached a picture of the way my wirless network is setup. What I'm worried about with 7bBi's the signal width is 30%, and with 9dBi's it drops to 25%.

However, I really don't like the idea of having antennas sticking out of the top of router a foot and a half lol.

Due to the walls I am leaning towards the 9dBi because I want to make sure I have enough power. However, it has three walls to travel through. I'm wondering if I should go with a 7dBi, or would a 9bBi be over kill for in the house? The laptop is about 30 ft away from the router.

I am looking to improve the signal even more by adding bigger antennas. There isn't much of a difference in signal to the other devices. However, the improvement I saw was mainly on the laptop that is positioned the furthest away. I figured that since they where external instead of the internal I would see a big improvement. I wanted to see if they would give me the performance I needed. The antennas I am currently using are only 3dBi.

This weekend I modded my WNR3500Lv2, and added external antennas.
