Slow OneDrive upload speed when using Ethernet

I'm using OneDrive for uploading all my files. My internet speed is 150-160Mb/s ~ 18-20MB/s (both upload/download) My OneDrive upload speed usually ranges from 18-20MB/s when I'm using Wi-Fi and that's exactly the highest speed my internet supports. Some how the upload speed is halved when I plug in my ethernet cable (8-10MB/s). The speed go up to 18-20MB/s when I unplug the ethernet cable and use Wi-Fi. It used to be 18-20MB/s but now its max speed is only 10MB/s.

I've tested my internet speed using speedtest.net and the speed when I'm using an ethernet cable is even a bit better than Wi-Fi. I've already chose Don't limit in OneDrive settings. I've checked and updated everything.

How do I make OneDrive upload my files at the max speed

Thank you.

Could be Send Large Offload on the IPv4 if youre using it. Should be able to find the option to enable from the network card settings/properties page.

Check if its enabled?

Hi batlhilz,

Thanks for your quick reply. I've checked that option and it's enabled. I've tried disabling it but the speed stays the same.

Okay, of course you could check the IPv6 if its on use from your broadband :) Im out of suggestions now tho

OK. Thanks for your help. Can you tell me more about your IPv6 suggestion? I don't understand that clearly
