I have three wrt54g with sveasoft alchemy ver 1.0 firmware, 10w hyperlink amplifiers and 10.5Dbi antennas. The wrt54g is placed 15 to 20km away from one another. The wrt54g are configured to work in WDS mode. May I know what are the parameters that would be affected and what parameters should i tweak to improve the throughput. The experiment is carried out in open sea.
