How to Speed Up the Internet on Ubuntu
You can speed up Firefox in Ubuntu. (notebook computer image by Lisa Eastman from

Ubuntu, the most popular distribution of the Linux operating system, comes with Mozilla's Firefox as the default Web browser. You can also download and install other browsers, such as Opera, Google's Chrome or Iron. There are a couple things you can do to speed up Firefox in Ubuntu.

Skill level:


  1. 1

    Open a Terminal by going to "Applications," clicking on "Accessories" and then "Terminal." Type "sudo su" into the Terminal and press "Enter." Type "sudo gedit /etc/modprobe.d/bad_list" into the Terminal. This opens a text file. Type "alias net-pf-10 off" into the open text file and then save and close it. This shuts off an unnecessary Internet protocol, IPV6. It often conflicts with IPV4, a protocol used by most applications, when accessing the Web.

  2. 2

    Type "sudo gedit /etc/sysctl.conf" into the Terminal and press "Enter." This opens a different text file. Copy and paste the following into the end of the file, then save and close it:

    net.core.rmem_default = 524288

    net.core.rmem_max = 524288

    net.core.wmem_default = 524288

    net.core.wmem_max = 524288

    net.ipv4.tcp_wmem = 4096 87380 524288

    net.ipv4.tcp_rmem = 4096 87380 524288

    net.ipv4.tcp_mem = 524288 524288 524288

    net.ipv4.tcp_rfc1337 = 1

    net.ipv4.ip_no_pmtu_disc = 0

    net.ipv4.tcp_sack = 1

    net.ipv4.tcp_fack = 1

    net.ipv4.tcp_window_scaling = 1

    net.ipv4.tcp_timestamps = 1

    net.ipv4.tcp_ecn = 0

    net.ipv4.route.flush = 1

    This speeds up your broadband connection by changing the size of the data packets that are being exchanged into more manageable sizes so as not to overload your connection.

  3. 3

    Type "sudo sysctl -p" into the Terminal followed by "Enter." This resets the text file configurations for broadband Internet after adding the information from Step 2. Restart your computer after completing these steps to assure all changes take hold.
