the situation I have is that one AP is reporting 87% signal, then if you walk literally 3 ft in one direction it drops to zero. The 2 closest AP's were xmitting on chan's 1 and 11, the ap in question was also xmitting on 11, so i changed it to 6, with the same results. I also tried 11 again with a lower power setting and still had the same results.
There is apparently alot of power conduit and coming out the top of the office I am trying to extend this signal to. I am also going to try some antenna with a higher db, I just find it odd that the signal goes from close to 90 to 0 in such a short distance.
