TL-WPA4220 keeps crashing when downloading things
I need help, the TL-WPA4220 crashes my internet when I'm downloading large files. Usually this happens when downloading games through steam, epic and other launchers but also on chrome: it starts downloading normally, but then after a few seconds my internet connection goes down. Plug out the powerline and plug it back in fixes the connection... but then when I start downloading again, the internet connection will crash again and again. It's almost impossible to download any game or large file.
I assumed it was the router's fault for a while. I called my operator but he said that there was nothing wrong with the router, I live in a 2 floor house. Is there something wrong, maybe with my sockets? I also tried to plug it in the same room as the main wifi, the connection was very good but when i'm in my room on the second floor the connection keeps falling when downloading big files or games… and i plug it directly in the socket as the instructions say!
I have tried updating the drivers, but it didn't help. Any solutions? It's so frustrating
