Hi Team,

I have been having a really annoying issue, I get really fast download speeds and upload speeds on all my devices except on my main PC the download speeds are fine, but the upload speed is 1mbps. it's been like this for a few months I've tried a lot.

At first, I thought it was the isp however I've checked with several other devices and come to the conclusion that it has to do with a setting with Windows as the problem persists with an ethernet cable or Wifi with the same speeds.

I've attempted to use the fixes in the link below but made it worse, I managed to reverse the settings and really lost with what to do.

    Hi again GhersonBorja,

    Thank you for the reply, I'm sorry to hear that

    there are some other possible solutions you can try

    1. Update the network adapter drivers

    Press the Windows + X keys on your keyboard, and then choose Device Manager from the context menu.

    Expand the Network adapters section. Here, simply double-click on the adapter you’re currently using.

    Switch to the Driver tab, and then click on the Update Driver button.

    Select the method of updating your driver. You can either let Windows 10 search for a driver automatically or manually locate a new driver file already on your computer.

    Wait for the driver installation to complete. Repeat this for any other network adapter drivers you use, and see if the internet speed has improved.

    1. Adjust the Network Bandwidth settings

    Press the Windows + R keys on your keyboard. This is going to bring up the Run utility.

    Type in “gpedit.msc” without the quotation marks and press the Enter key on your keyboard. This will launch the Group Policy editor.

    Navigate to the following location: Computer Configuration → Administrative Templates → Network → QoS Packet Scheduler.

    Double-click on the Limit reservable bandwidth setting. Make sure to switch the setting to Disabled, or manually edit the feature to a % you’re happy with.

    Click on the Apply button, and then restart your computer. See if your internet speed improves after making this change.

    1. Turn off Large Send Offload (LSO)

    Press the Windows + X keys on your keyboard, and then choose Device Manager from the context menu.

    Expand the Network adapters section. Here, simply double-click on the adapter you’re currently using.

    Switch to the Advanced tab, and then select Large Send Offload V2 (IPv4). Set the value to Disabled.

    Click OK and restart your computer for the changes to take place.

    1. Temporarily disable your firewall

    Press the Windows + R keys on your keyboard to launch the Run utility. Type in “firewall.cpl” (without the quotation marks) and click on the OK button.

    Click on the Turn Windows Defender Firewall on or off link, located on the left side of the window.

    Make sure that you select the “Turn off...” option for both Private network settings and Public network settings.

    Click OK and restart your computer. Check if your internet speed has improved after disabling the firewall.

    Best Regard

    Amr

    Hi Amrsh,

    Sorry to bring up this thread again but nothing suggested here or in the previous link have worked for me. For option 1, all my drivers were up to date. For option 2, I do not have access to group policies since I'm using Windows 10 Home. For option 3, Large Send Offload was not an available option. Finally, disabling the firewall did not make any permanent changes.

    Any further assistance would be appreciated!
