Thank you for bringing this to our attention.
We had a look at your speed and it is very different from what you are getting. Have you tried to test the speed on a wired connection? Perhaps it is a Wi-Fi related issue.
We'll wait for your response.
Our test results show that your modem is able to detect a download speed of 10.2Mbps from the line. You can also view this when you log in to your modem settings page.
For us to better understand what's affecting your connection speed, can you run a speedtest and post a screenshot of your results here? We suggest running the test via this site: speedtest.net. Make sure to run the test using a computer hardwired to the modem. Rerun the test again, but ensure that all other devices are disconnected from the modem (WIFI or ethernet).
