Seeni,

No we have not tried the dial power since our signal strength at the AP 
is reporting only 45%....  That is equivalent to -73.5 dbm signal.

When we had the total, we had a link strength of -70 dbm...  and had 
slower upload...  That kind of supports your theory, but the signal is 
only -75.. so I can't believe I am "over powering" the receiver... I have 
other links which are much better and don't have this issue...

Scott
