I am using WRT-54g with combination of 19 dBi directional Yagi. Distance between two WRT is about 4-5km. Signal stenth that I get on both sides is about -62db. But the connection speed is 5 MB (transfer rate about 180-200KB). I think (also with my previous expirience) that this is low speed. Anyone have some expirience in such distances ? I expect to achieve min 36 Mbit with this signal stength.
