Check your connection is working

On your modem, you’ll see six lights representing: power, Wi-Fi, network and three for signal, the higher the signal meaning the stronger the signal. Once your modem is up and running all lights will be on.
If there’s an issue with your connection, the lights on the front of your modem will help you to identify the problem. 

Use the speed test to see what speed your connection is running at once connected.
