Model: Archer AX20  
Hardware Version: V1
Firmware Version: 1.1.0 Build 20200326 rel.61977(5553)

Anybody had this issue where your router is plugged in a Gigabit Switch and the port negotiate 100Mbps Full duplex instead of 1000Mbps?

 

I have the latest firmeware - tried to reboot both my switch and the router but is still at 100Mbps - I have a 200Mbps Internet connexion which works fine on the wireless but limits internet speed when wired. 

 

 

Any ideas why and how to set it up? 

 

Nothing seem to allow me to force me negociation on the Advanced section. 

 

 

Thanks, 

 

Edit: I use a cat6 cable.

Hi,

 

For the LAN negotiation issue you encountered, please help confirm the below details and get back to the community if it cannot be solved, thanks.


1. What is the device connected to this LAN 1 port? It is suggested to change another wired device with gigabit ethernet ports to do a test. 
2. what is the negotiation speed on your PC? You may confirm it as below:

It is also suggested to change another cat5e or above cable. 

 

If none of the above works, please tell us the brand and model number of the gigabit ethernet adapter on that PC, we will check and investigate further, thanks.

@Anurag7108 

 

What is the device and model of the adapter that connected to the LAN port of the Archer AX20? Have you tried to connect other devices with a gigabit Ethernet port to one of the LAN ports of the Archer AX20 to check if the link speed can be 1000Mbps?


Try with different LAN ports, as well as different Ethernet cables, cat5e or cat6 is OK.
