Powerline and link issues

Hi, I have a Netgear Kit Powerline AV500 and i setted it with the same SSID of my router to have automatic switching Powerline or Router when I’m on better place in my house to receive the best wifi signal.
But when I use videocalls through Skype and i walk in my house to switch the wifi transmitters the calls close when I connect to new wifi transmitter.
Why Do I have this issue?

Because that’s normal within IP calling.
They cannot just switch between different devices and subnets also…
