    4. Then confirm the bbr modules is included...

    ```bash
    $ ls -a /lib/modules/$(uname -r)/kernel/net/ipv4 | grep bbr
    tcp_bbr.ko
    ```

    5. Grep to see the congestion control currently using in Ubuntu, for me, my default is using cubic

    ```bash
    $ cat /proc/sys/net/ipv4/tcp_congestion_control
    cubic
    ```

    6. Change the setting of tcp_congestion_control by echo, i did that in root

    ```bash
    $ sudo -i
    $ echo "bbr" /proc/sys/net/ipv4/tcp_congestion_control
    $ cat /proc/sys/net/ipv4/tcp_congestion_control
    bbr
    ```
