You can do that by either turning the other devices off, temporarily disconnecting them from the network or placing them in Airplane Mode.Ģ – If at all possible, run the test with a computer that’s connected to the router or gateway via a wired Ethernet connection. Here’s a little experiment for you to try:ġ – Make sure your computer or mobile device is the only device in your house that’s actively using your Internet connection while you run the test. In fact, even a tablet or smartphone that’s accessing a website or reading Facebook can lower the effective speeds delivered to other devices on your network by at least a small amount.

Put another way, every additional device that’s actively using your local network will lower the effective download speeds for every individual device that’s in use at that time. Instead, that amount will be shared between those devices. That 200 Mbps is then divided up among all the computers and devices that happen to be using your Internet connection at any given time.įor example, if someone in your house is streaming a movie while you’re watching a YouTube video, neither of your devices are going to be receiving data at the full 200 Mbps.

That means Comcast is promising to deliver 200 Mbps to your modem/gateway. You said you’re paying Comcast for a download speed of 200 Mbps. Please allow me to explain why having multiple devices in use while you’re running the speed test matters… You didn’t mention how many computers and other devices were using your Internet connection at the times when you ran your tests, and that makes a huge difference. While there’s always a chance that the Comcast tech you spoke with just told you that to get you off the line, I have a hunch that you are indeed getting the speed you’re paying for. Rick’s answer: Checking actual Internet download and upload speeds can be a little tricky, Kellie. Is there something I’m doing wrong when I run the speed test or is Comcast just blowing me off? I called Comcast this afternoon and they ran some kind of test from their end and said I was getting all the speed I’m paying for. The fastest speed I got was around 65 Mbps. I used to run several speed tests yesterday and again this morning. Question from Kellie: I have Comcast Internet and the plan I’m on is for 200 Mbps download speed.
