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.
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.
