Troubleshooting Archer AX6000 Slow Upload Speed
This Article Applies to:
Archer AX6000
Archer AX11000
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 whether 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.
