    Why is my pc download speed slower than every other device


    My pc download speed is only reaching 90mbps while on my phone it reaches 500mbps. Just last week my pc had 500mbps download speed. Why has it decreased so dramatically?I have reset my pc multiple times including my actual wifi and even reset my network on my pc and nothing has changed.

    :)

    Wifi speed slower on pc than on Iphone.

    I found the service (CFosSpeed System Service) causing my Upload and Download speed to drop significantly. I had about 5 Mbits/s Upload, which probably caused my ping ingame to be so high. But my Download speed is still slower than on my other devices.

    Testing

    Regular (promised) speed: 250 Mbit/s Download & 50 Mbit/s Upload

    Actuall speed:

    • PC: 165 Mbit/s Download & 50 Mbit/s Upload
    • Iphone 11: 240 Mbit/s Download
    • Samsung A52: 240 Mbit/s Download
    • Iphone 13: 220 Mbit/s Download

    I am satisfied with this fix, since I can enjoy games again, but if there is a possible solution for my drop in download speed, i would greatly appreciate it.

    Download speed slower than upload speed

    My Windows 10 desktop has slower download speeds (10Mbps) compared to upload speeds (30Mbps). On other devices connecting to the same router, I can get download speeds of 90+MBps on our 100/40 plan.

    This is true whether I connect with ethernet or wifi.

    I have changed the Windows update settings that limit how much bandwidth is used for downloading updates.

    I have changed the NetworkThrottlingIndex registry setting to ffffff.

    Is there some other Windows setting I can find and change, to improve this?

    Thanks in advance!

    Why is my pc download speed slower than every other device

    Download speed decreased to 0.2mbit (from 6mbit) after upgrade from Win8 to Win10

    Hello,

    im experiencing very strange problem because download speed after upgrade to Win10 has decreased. Upload speed is still about 20Mbit/sec. I tried following:

    • multiple network devices- Primary is LAN adapter, secondary LTE phone. Altough the ping is different and upload speed on LTE phone network is slower, both network connections suffer from very low speed (0.2Mbit). And yes, I tried different pc and
    • newest drivers installed
    • dns cleared
    • antivirus uninstalled, no malware found. No improvement in speed either
    • p2p update redistribution disabled
    Before reverting back to Windows81, do you have any suggestions?
