fix the transmission rate of you AP [if supported by the firmware]...

what router are you using? if you want to have a 1 by 3 or 2 by 3 CSI you should either buy a router with 1 or 2 transmitting...

you have to fix the transmission rate to solve the problem of varying Rx and Tx... it's hard to find a commercial AP that supports this feature.
