Internet speed Questions

We are signed up for 1 Gig service. We are using Comcast's Equipment. When I go online and check the internet speed from our login portal it shows 928 mb Down and 42 mb Up. Exactly what I would expect.

I take a Brand New laptop just purchased and plug it into the back of the Cable Modem with a CAT 6 cable using Xfinity's app and I get 620 mb Down and 40 mb Up. How do you lose 300 mb? Then when you run it through the network and switches I end up even lower. Old Equipment and I understand that.

I have had technicians come out and they hook up their testing units to the ports on the back of the modem and they show the 900 mb but that is not a real world computer. Why am I paying for something that I am not able to achieve?

Is there a answer for this? I know that if I call about it they will show me that the modem is working correctly and giving me the speeds we are paying for.

When it comes to the internet, the speeds will fluctuate and never be the exact same every time you run a speed test. Granted, if it is always at 600 with our Gigabit speed, there is something that is going on. Is your modem connected directly to the wall, or is there a splitter?

Our speed test is going to be the most accurate. Have you tried using a different ethernet cord?

Yes I have tried different brands of cables and different Etherenet ports on the back of the modem. When the technician runs his testing unit to the same ports he gets the 900+ mb speed and usually their cables look like they have seen some use.

Yea, I am not sure what be causing your equipment to get a lower speed then. That really doesn't add up. I'd like to look at a few things from our end. Can you send us a DM with your name, and address?

- Click "Sign In" if necessary

- Click the "Direct Message" icon in the top right corner
- Click the "New message" (pencil and paper) icon
- The "To:" line prompts you to "Type the name of a person". Instead, type "Comcast Business" there
- As you are typing a drop-down list appears. Select "Comcast Business" from that list
- An "Comcast Business" graphic replaces the "To:" line
- Type your message in the text area near the bottom of the window
- Press Enter to send it

I no longer work for Comcast.
