Are you being “Comcast-ed”? Test your speed every 5min and see if you're getting what you're paying.

comcasted

Sometimes Comcast is too fast, you feel a need to measure your speed and save to a CSV so you can prove you are getting the speed you are paying for.

This script is designed of OS X and periodically runs a speed test when you are are connected to a wireless network (or a specific wireless network). It is also not Comcast-specific but I decided to name it so because they're such a great ISP.

Installation

Clone this repository locally and go into the source directory

git clone [email protected]:ahmetalpbalkan/comcasted.git
cd comcasted

Install the periodical job using osx.sh script. Once installed, the speed test script will be executed every 5 minutes and place a file called comcasted.csv on your desktop to report the test results.

Usage: ./osx.sh <command> [<ssid>]

Arguments:
<command>	'install' or 'uninstall' to set up the program to run in the background
<ssid>		(optional) run speed test only when connected to this wireless network

Examples:
  $ ./osx.sh install ahmet-home-wifi
  $ ./osx.sh install # (runs on all connected wireless networks, use at caution)
  $ ./osx.sh uninstall

Visualizing

You can use the nice ./visualize.py script to upload the CSV file to charted.io and get a visualization like this:

(If you already installed using osx.sh script, it will find where the data is located automatically)

./visualize.py 4

Tweaking

If you want to run the speed test once, you can use the comcasted.sh.

If you like to configure the periodic speed test interval or where te results are saved, you need to modify the .plist file and re-install the launch agent using osx.sh command.

If you configure your computer to not to go sleep when plugged and leave the lid open, it can run over the nights while you're sleeping as well.
