Hi there,
There's something strange going on with my internet connection,
So one month ago there was a thunderstorm and my monitor became black for two seconds and i heard crackling. I switched my PC off then after some time i switched it back on. Everything was fine except my internet. After many days i finally understood that it was my LAN card. It was broken (sorry idk the exact word). Today i bought a new one. I installed both it and the drivers and i went to that Test Speed site you know it and it was fine (my internet speed is 70mbps, the internet in my country is fast!...) Well, a few hours have passed since then and i felt it slower (btw there's also a lag when i switch between Google Chrome tabs). I entered that same site and now it's only 9 mbps. And i have no idea why did it happen. I haven't done anything since then. Please help me! :/
