As the title says, my wifi suddenly drops to very low speeds every few minutes. It gets so slow it's like it's disconnected but my wifi indicator says I remain connected. I am very new to linux but I know the basics (using the terminal and such). I just have no idea how to debug it as I do with windows.
So I will provide some basic data and please request any additional information you need.
