Thank you for contacting Intel.
Most high-speed internet connections provide fast download and slower upload speed. This is because most users download more (accessing multimedia files) than they do uploading.
Here are some settings that you may try to improve the adapter's throughput performance:
1. Reduce Interrupt Moderation Rate to Low, Minimal, or Off
2. Increase the Transmit Descriptors buffer size. The default is 256. Maximum value is 2048.
3. Increase the Receive Descriptors buffer size. The default is 256. Maximum value is 2048.
4. In Performance Option, disable the TCP/UDP Offloading options.
Refer to website below for more information:
Hope this helps improve your internet upload speed. Feel free to contact us again if you need further assistance.
