I'm only about 40 feet away but it has to go through a cinder block wall to where I'm at. I may have not needed such a good one, I think the primary issue was my older router simply sucked that bad. The final straw was when I tried transferring a huge amount of data from my old computer and it was giving me like 100kbps and estimated time of 2 weeks.
I don't know what the particular issue was there because I was able to get faster speeds over the internet but that was enough of messing with it.
Right now I'm getting maximum bars and speed, I tried a new wireless adapter first and that didn't solve the issue. I'm picking up two neighbors routers with it and the one is consistent two bars. Closest house is easily 150 feet away. Nice thing about that is you can mount the antenna somewhere else if you need too.http://www.newegg.com/Product/Product.a ... 6833166056
