| 1488851 | 2022-10-12 03:25:00 | When I run speedtest on my main machine I get ping of 3 and speeds of 328/95 Mbps. Yippee! When I run it on another machine on the other side of the room with a wired connection I get 94/94Mbps. Why might this be? When I look at my Huawei router config, that other PC is identified as "hostname006". Can I change that to something more identifiable? |

| 1488852 | 2022-10-12 04:12:00 | What's your expected Internet speed? Are they both on wired? If both wired it's possible that the one getting 94/94 is in 100Mbps mode versus 1000Mbps? Yes you can change the name (assiming you're on Windows 10) by going to Settings--->system--->Rename this PC--->change the name---->Restart the computer. |

| 1488853 | 2022-10-12 04:50:00 | I’d say either the machine. Only has a 100/100 “fast Ethernet” network card. Or possibly a faulty cable, or in its network interface settings it could be forced down to 100 megabit network instead of gigabit. I assume both machines are directly connected to the same router? No other switches in play? |

| 1488854 | 2022-10-13 11:21:00 | Definitely sounds like the slower one is limited to 100Mbit, for some reason. | Agent_24 (57) | ||
| 1488855 | 2022-10-14 02:35:00 | OK, after a lot of faffing about, here is what I have come up with. The "slow" machine is indeed running at 100/100, this despite me changing the network adapter to force 1gb full duplex. On another forum I saw a post that suggested the cable could be faulty, and apparently after changing to CAT6 cable the problem went away. So I'm going to invest in a 1m CAT6 cable, which fortunately is all I need and see if that makes a difference - unless anyone has other ideas? Chiefnz - renaming the PC doesn't make any difference to the name in the router config - it is still "hostname006". |

| 1488856 | 2022-10-14 04:13:00 | Could be the cable, yes. You could try swapping out the cable from the other machine to do a quick check, before you buy another one. I have also had Ethernet not work at gigabit speed because of outdated drivers. If you can, get the latest drivers from the card's manufacturer or the motherboard maker. Windows Update doesn't always work. You might need to change the hostname in the router itself then, it might have assigned its own display name and is ignoring the actual hostname, or delete it and let it re-add the machine with the new hostname. |

| 1488858 | 2022-10-15 06:37:00 | Not using a 100Mb switch in the circuit at all? because that'll do it. Bit of a story behind why I ask. 100Mb uses 2 pairs of wires, one for send and one for receive. 1Gb uses 4 pairs of wires, each pair for both send and receive. In theory if a cable has a faulty pair as long as it's not one of the ones used by 100Mb then a Gb connection will auto negotiate down to the slower speed and still work. However in practice I have found many Gb connections will detect that both ends are Gb capable, try to use Gb speed, and just fail to work completely when the cable is faulty. I found this out because I had a cable wired only for 100Mb with 2 pairs of wires and it refused to work with Gb ethernet until I inserted an old 100Mb switch into the circuit to force it down to 100Mb. Basically any active 100Mb device in the circuit will force the connection to run at that speed, and a cable without all 4 pairs MIGHT also cause that. |

| 1488859 | 2022-10-15 07:46:00 | That's interesting. All the devices on the network (2 PCs and a printer) are 1Gb capable, as far as I can see. I don't know about the cable to the "slow" PC. As I said, I'm going to get a CAT6 cable and see if that makes a difference. It is not a big deal. "only" 94Mbps is still pretty good for those of use who can remember 9600baud modems. :) I'm really only following this up to satisfy my inner geek. | Tony (4941) | ||
