@TP-Link 

I have chosen bank 3 & 40, but it always connects to 40 & 40 why? refer to the screen attached. 

earlier a few months back it's used to connect 3 & 40 properly for the same settings only then I will get good up/down speed. 

So now, I able to connect either with 3 (setting band B = empty) and 40 (setting band B=empty) separately. 

whereas 3 & 40 aggregations are not happening, even if aggregation failed, it should connect to only one bank 3 or 40, should not be 40 & 40 as per setting, right?

please refer to the screenshot and suggest.

@Hemantjhr

@Satheskumar 

How to downgrade it to v1 ?

@Hemantjhr 

It is possible only if you buy older router MR600V1

You already have better device and firmware, Why do you want v1 ?

Its been a year i have been using the External LDPA's it was working great. from past month i see decline in speed and signal. Now its like almost gone. I am confused whether antenna's degrade by time. Should i need to buy new pair again or is it Tower issue which am pointing to. Any one experienced this?

Can some one please explain me this

if i run speed test in Firmare page am getting this

same thing if i run in browser am getting this

Which one is true. Am truely confused as to which one is correct. i tried connecting laptop through LAN and ran test but nothing goes beyond 10mpbs but in firmware it always clock more then 25mpbs. 

No band selection would not be a problem, if it would do it right automatically!

THIS is the problem:
