    Test patching directly into router, not via internal cabling.
    Test different cable.
    Test with different laptop.

    Just for fun: test WiFi, preferably 5 GHz. If that nets you more than 100 mbit then your router/ISP is the issue.

    Also, what do you get when testing on e.g. Speedtest.net?

    check for damaged pins in ethernet ports. gigabit uses 4 pairs and 100 meg uses 2 pairs so maybe a bad connection in one of the ports.

    Here are my checklist when this happens.

    1. Check the NIC on the machine and see if it supports 1 GBPS
    2. Check the ethernet wire to see if the cable is properly terminated or not.
    3. Check the port on the switch/router you are connecting to and see if that’s the culprit.

    This just happened to me today lol, turns out my old Dell laptop doesn’t have a gigabit port. Got full speed on Apple TV and new laptop.

    99 times out of 100 this is an issue with the cable. Be it the one in the computer or the one in the wall.

    Almost certainly the NIC in the PC. The fact that it’s exactly 100 sounds like a misconfiguration

    I’ve seen 5-6 Asus Zephyrus laptops refuse to connect at anything other than 100Mbps, even after turning off the auto-neg and setting it to 1G, they would still connect to the switch at 100M.

    This has all been within the last 6 months, I wonder if they released a broken driver for whatever NIC they’re using.

    Even if you have a cat 6 rated cable depending on the cable itself, the NIC and your router will validate if it can reach 1GB speeds, if the twisted pairs in the cat 6 cable are degraded in anyway then the NIC and the router will negotiate to a speed it can support, which may be your issue here. I would try using another cat 6 cable you know is good to validate if its just a bad cable or not.

    or lets say ha

    large chunk of laptops are 100mb ports. for cost cutting.

    cheaper to do faster chip with wifi . then a a wired chip.
