I only have a 1 gigabit connection and my router is 1 gigabit. How does this happen? (alien.top)

Some testing software in my experience can give you a higher speed than what you are getting and vice/versa.

For example the Xbox internal test in settings can give me a speed of +600mbps whereas a Google test on a wired connection can give me 300mbps on a 550mbps connection

    Additionally, some ISP's may over provision by whatever % to cover overhead and other things.

    This is Exactly what my ISP does. So I don’t know why you are being downvoted. I pay for symmetrical 1Gb. I receive, as tested through speedtest.net, 1060Mbps down and 1040Mbps up. In order to receive those speeds, I had to test from a computer with an ethernet interface faster than 1Gbps. And of course the router would also need to support the higher bandwidth link. My Mac Studio has a 10Gb interface; and my router has a 2.5Gb interface. If you have a router with WiFi 6 or 6e capability, you could also exceed 1Gb with that (providing the device you are testing with also supports it).

    Yeah, I'm confused why he's being down voted. I do find Fast dot com to be inaccurate and likely that's why he's seeing this, but I work for an ISP and every customer is overprovisioned. It's more common than not if testing with a capable device, especially hardwired, they're getting more than what they pay for.

    That is correct. E.g. a 500 Mbps subscription is configured as e.g. 540 Mbps, so that overhead will not impact a speedtest.

    But with a 1Gbps connection, setting 1.1Gbps might not be possible as the modems/routers can have a 1Gbps port, so there is a "hard limit" on 1 Gbps. Because of overhead, you will typically only get around 950 Mbps on a 1 Gbps connection.

    As for Fast, I have seen the same thing as OP. I can get 1.1Gbps on a 1Gbps connection that normally is "limited" to 950-isj Mbps on other speedtests. The modem internally supports more than 1 Gbps, but is limited by the Ethernet-port.
