I am using AR5413 cards for wlan1/2/3 all part of the same WDS. wlan 1/2 are backhaul links and wlan 3 is for clients. I have tx and ack timeout set to default for wlan 3 but all the clients that register have -53/-61/-65 and excellent connections but it says -SP next to them and there tx/rx rates are 1mbp-SP/18 and what not. I thought it might be interference so I stuck wlan3 on a different bridge and selected a less noisy channel but I am experiencing exactly the same problem. What should I check to remedy this transmit rate low issue? Below is the original config.
