Before you begin the Broadband Speed Test, below are some tips to get accurate results
Close All Applications
Close everything such as Pandora, Netflix, Hulu, Spotify, all browser windows and tabs (except the one you're using for the test) and any other programs that stream video and music.
If it uses the Internet, you'll want to shut it down before you run the test.
Connect Directly to Modem
Connect your computer directly to your modem
Run the test with a single device connected directly to your modem using an Ethernet connection
Remove any hubs, switches, or routers between your computer and the modem
Power Off / Shut Down Devices
Turn off or unplug other computers, web-enabled printers and TVs, other routers, tablets, smart phones, web cams, DVRs, game systems, VoIP phones and content streaming devices such as Roku, Apple TV, and Chromecast.
