Model: Archer A6  
Hardware Version: V3
Firmware Version: 1.13.6

My router is changing the speed limit of the LAN 1 port. Sometimes it's at 100 Mbps, and other times it's at 10 Mbps. How can I stop this from happening? My PC is connected to LAN 1 via an Ethernet cable, and when the router changes the negotiation, my PC slows down and I experience frequent connection drops.

Hi@Vasco2529,

Here are some suggestions may help you:

1. Please change the cable and port to confirm whether it is a hardware problem;
2. Please try to adjust the placement of the router to reduce heat dissipation and interference from other devices;
3. Hard reset the router for a try.
