Issue Description/Background:

Some customers reported the upload speed is much slower than that provided by the ISP when connecting to the Wi-Fi router even with a cable connection. The download speed is as good as expected. This article aims to guide you to get this resolved.

Troubleshooting Suggestions:

1. Ensure you get the correct expected download and upload speed when connecting the computer directly to the ISP-provided modem. This is very important, which will help address if the issue lies actually in the ISP modem or in the router.

2. If point 1 is confirmed and the download and upload are good, please login to the web interface page of the TP-Link router, check if the Internet Negotiation Speed is 1000Mbps Full Duplex, manually change it to that if it is on Auto or 100Mbps:

3. If you have ever modified the QoS settings on the router, check the following to see if that helps with the upload speed:

-Set the total bandwidth speed manually to that higher than your actual speed or more than 999 Mbps for up and down (Advanced > QoS, top of menu);

-Set the application priority to Standard (Advanced > QoS > Application Priority);
-Disable any device priority (Advanced > QoS > Device Priority);
-Disable HomeCare features (Advanced > Security > Antivirus);

-Save and reboot the router.
