Alternative QoS Setup: Ubiquiti EdgeRouter Pro for CrazyCall

The first step in the process of activating QoS on Ubiquiti EdgeRouter Pro is testing your bandwidth. It’s necessary as you’ll need the exact numbers regarding both Download and Upload speed to properly set up QoS.

How to test your bandwidth

Before you run the test, deactivate any traffic shaping or firewall rules that you may have already set. Also, run the test outside of your business hours to get unbiased results.

1. Go to www.speedtest.net and run three separate speed tests one after another. Make sure you save the results of each of the tests.

Now, let’s assume you got the below results:

Test #1: Download 97Mbps / Upload 79Mbps

Test #2: Download 90Mbps / Upload 84Mbps

Test #3: Download 98Mbps / Upload 76Mbps

To set up your Ubiquiti EdgeRouter Pro we will make use of the lowest results, here being the 90Mbps for the download and 76Mbps for the upload.

2. Now you have to access the Ubiquiti EdgeRouter Pro CLI via the web interface or ssh access (ssh ubnt@192.168.1.1)

3. Next, type in the below rules

NOTE: If you decide to copy-paste the command lines we provide below, please do it in the following order: Start -> Download Rule -> Upload Rule -> Finish
