Ubuntu – Ubuntu 14.04 LTS wired internet extremely slow


My wired internet is running extremely slow after installing Ubuntu 14.04 on my desktop. my normal internet speed (Windows) using speedtest.net is around 25 mbps, Ubuntu is pulling in 0.5 mbps tops.

I've found lots of issues with the 'Realtek RTL8111 Ethernet Interface' I've got, they all say to change the drivers to r8168 (which I've done) or change the IPv6 to ignore (also done) but my internet is still running extremely slow. I've tried everything I've been able to find online and rebooted multiple times along the way but all to no avail. I don't have much experience with Linux, but am eager to learn.

What do I need to do to fix this problem?

Best Answer

  1. Disconnect from Internet
  2. Open your Terminal and execute the line:

    sudo tee /proc/sys/net/ipv6/conf/all/disable_ipv6 <<<"1"
  3. Connect to the Internet again, and see if the problem still exists.
