Arch Linux

Hi, guys. I'm wondering if there's any way to limit the download speed from within Arch? I have made settings for that in the router CP but they don't seem to work bc Arch is completely ignoring them and keeps downloading with the full bandwidth it can get.

The thing is that our IPTV is from another provider which is why I need to leave some bandwidth for the TV. When I'm downloading something directly (meaning from FTP or TCP), even if it's just for a fraction of the second, the TV dies instantly. That's why I need to limit the download speed somehow - preferably from within Arch.
