Low speed with wired/wireless connection on Archer C7
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hi team, I'm facing an issue with slow speeds with both wired & wireless when connected to router (Archer C7).
ISP : ACT broadband, Speed : 300Mbps
Router : Archer C7 v5.0 1.1.2 Build 20210125 rel.37999(5553)
Connected the cable from ISP directly to laptop and ran speed test to make sure ISP is giving the claimed speed. Got ~290Mbps both download & upload
I have done below debug but still see that the speed is low :
- Checked the duplex on router and its at Full duplex 1000Mbps
- Rebooted router , power off/on
- Router has latest FW
Anything I'm missing or the router has gone bad?
Thanks
Manu

What is the speed you got when the same computer is connected to the C7 by cable? What is the link speed on it? You can check this guide to get the link speed.
What is the speed you got when the laptop/phone is connected to the C7 2.4G or 5G network, what is the link speed on it? You can check this guide to get the link speed.
Check and ensure the QoS settings on the C7 is disabled, which may affect speed is it's not configured correctly, you can check this.

Hi @Kevin_Z,
With wired and wireless connection(2.4 & 5 Ghz) to Archer C7 I get 10-11Mbps.
QoS is not even enabled on the device.

What is the link speed on the computer when it is connected to the C7, wired or wirelessly? Please refer to the guide I provided earlier to confirm it, thanks.
Another suggestion, you can try to reset the C7 to factory defaults by pressing and holding the reset button for 10s, then reconfigure it from scratch, just set up the internet on it, don't change any other settings, then connect the computer to the C7 with cable, test the internet speed again, be aware of the link speed as well, as that will determine the actual speed you can achieve.

I used a 2ft cat6 cable for the link between TP link router & laptop, the shows up as 1000Mbps on the router web administration page as well on the laptop(1Gbps). I will try the factory reset today and update the results.
