Slow Xfinity Fibre

[keef_ca]

I just got a Xfinity fibre (well cable...) modem on a 2g plan. It in bridge mode and I get 1g down. I realize it is UP TO 2g however only getting half is a little much.
Anyone else faced this?
Thanks, Bj

I have a 1.5 Gigabit service and get download speeds approaching 1.9 Gbps.

The XB7 and XB8 gateways have 4 Ethernet ports:  Ports 1-3 are 1Gbps; port 4 is 2.5 Gbps.  If you are not connecting to the 2.5 GigE port, your download speed will max out at 940 Mbps.

You also need to ensure that all devices on the network path operate at 2.5 Gbps and can sustain those speeds.

If you are performing speed tests from a Windows system, there are a number of things (hardware/driver, configuration or tuning-related) that can significantly slow down data transfers.

If you want to confirm that there are no problems with your Internet service, disable Bridge Mode on your Xfinity Gateway and perform a speed test using the Xfinity app, and that will test the speed between your Xfinity Gateway and a Rogers server.

Thanks so much. That was it. Just over 2g now. I appreciate the reply.

What was it?  Please elaborate. Thanks.

My wife says I do that. I assume too much.
Connecting to the 2.5g port on the router was it.

Thanks. Glad the solution was quick and easy.

thats because the modem/router combo they give you (xb7) uses the only 2.5 gbps port  and the other 3 are 1gbps ports making it so that even if you use a switch you cannot actually receive the speeds they tell you the more optimal thing you will have to do is buy your own router  and work from there to make sure you receive the speeds they tell you you can get
