Powerline Discrepancy Transmission Rate Differs Between two Adapters on same circuit, why?

Hi there,
I have purchased a TL-PA9020P-Kit version 4 in Canada. Both adapters are in the latest firmware, 3.2.4_902104_190506_901.
I am wondering why i have such a discrepancy transmission rate between two adapters. Should they not be roughly equal between each other?
*This is a home/house setting (not an office building). House probably built in the late 70's or 80's.
Using the PowerLineUtility.exe installed on my Windows laptop, i have the following display to the Powerline transmission between both devices:
Adapter A ------------------------------------------------> Adapter B 126 Mbps (yellow powerline indication)
(first floor connected to router) (second floor)
Adapter B ------------------------------------------------> Adapter A 24 Mbps (red powerline indication)
(second floor) (first floor)
My question is, why is the transmission rate from adapter B to A so much so much slower? (and logically it should be on the same electrical circuit?)
Thank you if anyone can explain this,
Jobu.
Hi Solla-topee,
Thanks for your response.
The lower rate adapter is indeed plugged into the wall.
Generally speaking, there are no major appliances around each device. I've also made sure to turn everything off and run this at night with minimal appliances running to keep the circuit "clean" as possible.
So did some investigating:
1. I moved the Adapter B downstairs to the same room to be right beside each other (as in the next closest outlet).
Looks like the rate increased for each one, but it adapter B is still transmitting back to A at half the time A is to B:
2. I carried out your suggestion and swapped the two adapters....now it looks like A is the one transmitting back to B at half the rate!
So i guess the problem isn't really isolated to one adapter..
Any other ideas as to what could explain this weird phenomena / behaviour?
Much appreciated,
Thanks!
