Extremely LOW UPLOAD SPEED in Archer C6

2021-09-24 18:33:18

Model: Archer C6

Hardware Version: V3

Firmware Version: 1.0.10

I am not getting the ISP provided Upload speed in my router. The Download speed in OK, but the Upload speed is below 50% of provided speed. I have no idea why it's happening, if anyone has any solution please share. Thank you.

I have a Fiber connection.

I have 100Mbps plan.

My Download speed - 100Mbps+

Upload speed - 34Mbps

Name of my ISP - Alliance Broadband

Model of the ISP provided modem - It's a EPON ONU

Download and Upload bandwidth provided by ISP - 100Mbps

Speedtest result when connecting the ISP modem directly to my PC - 100Mbps+ (both Download & Upload)

Speedtest result when connecting to the TP-Link router with an Ethernet cable - Download 100Mbps+, Upload 30 to 40Mbps

@Logan_Gaming

Hi, how about the QoS settings on the C6, is it configured correctly? Follow this guide to confirm it:

https://www.tp-link.com/support/faq/3069/

If this doesn't help, please do a factory reset on the C6 as follows, reconfigure the router to connect to the internet, please don't change any advanced settings on the router, then perform a speedtest by connecting a computer to the C6 with a cable. If the upload speed is normal in the default mode, then try to do the modifications one by one to find out which change will cause the issue.
