Hello everyone, i'm trying to understand why the system is behaving in the following way and a possible soultion if there is any
I've had the TL-PA7010P KIT for 5 years without any problem; i decided to buy another power line to have also wifi, but with the introduction of the new device, the network is having bad signal.
The issue is only one way however, from the new device to the master and not the other way around.

Left is the new device [TL-WPA4220], right and bottom are the [TL-PA7010P KIT]

Has anyone encountered this problem? Firmware are up to date for the new device and the old kit had no firmware released ever
