How to slow down internet connection?

  • 772

I have a very large download to perform which is low priority.

Can I throttle back the networking speed of my Ubuntu 18.10 so this download does not bog down my connection which is shared with other computers?

I am on a home wifi connection.

I can use a browser to perform this download or wget, etc... yet do not see such a setting.

    wget has --limit-rate option for limiting the download speed; from man wget:

    --limit-rate=amount

    Limit the download speed to amount bytes per second. Amount may be expressed in bytes, kilobytes with the k suffix, or megabytes with the m suffix. For example, --limit-rate=20k will limit the retrieval rate to 20KB/s. This is useful when, for whatever reason, you don't want Wget to consume the entire available bandwidth.

    This option allows the use of decimal numbers, usually in conjunction with power suffixes; for example, --limit-rate=2.5k is a legal value.

    Note that Wget implements the limiting by sleeping the appropriate amount of time after a network read that took less time than specified by the rate. Eventually this strategy causes the TCP transfer to slow down to approximately the specified rate. However, it may take some time for this balance to be achieved, so don't be surprised if limiting the rate doesn't work well with very small files.

    FWIW, curl also has a similar --limit-rate option for controlling both upload and download speeds. Check man curl.
