  1. Internet speed loss

    My internet speed is supposed to be 300mbps, but when I test the speed on my desktop computer which is running Windows 10, it only go up to around 90mbps. Both on ethernet or wifi. It used to be 300mbps. When I test the internet speed using my phone, it is 300mbps alright. I contacted my service provider, there is no issue on their end. They suggested that it may be because of my PC.

    I already try these troubleshoots:

    - resetting winsock

    - flushing dns

    - reset ipv4/ipv6

    - remove bandwidth limit

    Please help

    Internet speed loss

    Slow Internet speed on only one computer.

    Hi Cody,

    Slow internet speed on one of your computer could be due to the following:

    • Outdated network adapter driver
    • Different Wi-Fi chipset
    • Computer processing speed

    Make sure that the network driver of your computer(s) are always updated.

    We also suggest you to contact your internet service provider for them to check your internet connection speed and give you more information.

    Feel free to post back if you have other concerns.
