I have 2 WRT54G routers using WDS... The first one is on the second floor of an apt building and the 2nd one is in the basement, in a window, and they share the same side of the building, approx 25 feet apart.... Im using some antenna design from free antenna.com, and its increased my max speed to 36mbps from 11mbps. The problem is that I cant maintain the higher speeds. It constantly fluctuates between 36 and 11 mbps. I think it may be people using 2.4GHz phones in the building but can anyone tell me another reason I may have overlooked why my conection speeds would be inconsistent?
