@linkzhao sure. Although can i ask you a question? Did you try using a router as transmitter and laptop with 5300 as receiver? When i try pinging and logging CSI i see that for some packets my no. of transmit antennas and no. of receive antennas vary. Like if i ping 100pkts/s for say 2-3 minutes some packets show Nt=2,Nr=3 some show Nt=1 Nr=2 and it keeps varying. Do you happen to know why?

i have not meet such problem，maybe you should check your antenna and try to change a router

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.
