I am not sure about the default behavior of your particular WPA4220. I remember some TP-Link devices have automatic synchronization switched on by default. If that was the case, then you would need to switch that "Wi-Fi Move" feature off to prevent them from synchronizing.

 

Ok thank you so much, i'll give you update of how it went when i get home and try everything you said.

Hello.

I have done what you said, everything is fixed except i couldn't plug the TL-PA4010 on a wall socket and my ping every 30 seconds goes from 20-40ms to 200-2000ms, do you think that plugging the TL-PA4010 into a wall socket may solve this problem?

I would try this but I can't because i don't have a LAN cable that can reach the router and the TL-PA4010 if i plug it to the wall. Do you know why my ping goes up and my upload and download speed slower?

There are plenty of things that can affect the performance of Powerline adapters. From the distance it's impossible to say what causes the lower speeds in your case.

 

It's also impossible to predict whether plugging the TL-PA4010 directly into a wall socket solves your particular problems. The general rule is that the longer the wires between two Powerline adapters the lower is their performance and the shorter the wires between two Powerline adapters the better is their performance.
 
By the way. When connecting a Powerline adapter via an extension lead make sure it is not one with built-in surge protection or noise filter, because these are known to reduce the performance of Powerline adapters considerably.

So this is how my ping is, as you can see it can go to 1000 or it can go to 30 ping. I just don't understand and by the way I plugged the TL-PA4010 like this:

I don't know if it's like in the wall socket or it the power circuit is less. I'm sorry if I'm not being explicit because I'm not English.
