Friday
Model: TL-WPA4220 KIT  
Hardware Version: V1
Firmware Version: 1.3.1.2141-00_422091_170518_004

I have a TL-PA4020P near router and TL-WPA4220 in salon room. Last 10 years works very good. The last 6 months have intermittent breaks of signal (Pixel and screen not updated but song is good).

The TV provider is Vodafone in Spain. This only happens when there is a program with very high audience (football, news) . And curiously if i see this same program twenty minutes later, going back, all work perfectly.

If i see a TV channel like Amazon Prime or Netflix, there are not any problem in one hour and a half for a film. 

 

The provider always says there is a problem in PLC. But i thing is his problem or perhaps there is something i can make to solve this problem?

 

i have Though change hardware version , but is a relative high inversion and perhaps will have the same problem.
