I would suggest using a wireless sniffer to look at this; preferably one
that is able to receive IEEE 802.11g frames. WDS links do not usually
use any kind of association, so it is possible that the IEEE 802.11g
device believes that the other end is capable of receiving IEEE 802.11g
Another test would be to run a unidirectional (e.g., UDP stream)
throughput test in both directions. The IEEE 802.11b to the IEEE 802.11g
direction should get much better results if the IEEE 802.11g device is
indeed using OFDM rates.
