Windows 10 IPv4 Checksum Offload

Anonymous

I'm experiencing some odd phenomena with the IPv4 Checksum Offload on various Intel & Realtek NIC's for the past few months. The only way I can get rid of the yellow triangle over the network icon is to disable IPv4 Checksum Offload. It doesn't bother me that the triangle is there but it doesn't allow OneNote, OneDrive, O365, etc to sync or validate activation and after any Win10 update it's re-enabled .....

Is there a port I need to open on the firewall?

    Hi

    My name is Sarah Kong and I am an independent adviser that is here to try and help you with your issue.

    You can disable this using powershell.

    To do this search for Powershell and then right click and select run as administrator.

    Then type the following.

    Disable-NetAdapterChecksumOffload -Name "*" -TcpIPv6

    See link below about cmdlet.

    Thanks for the reply but I'm thinking I need to enable a type of traffic or open a port on the firewall. Otherwise I'd have to push a PS script out to every user (500+) and it'd get re-enabled after another update.
