I’m having issues setting my routers' WAN port to 1000Mbps/Full Duplex.
My config is as follows:
- Raycore fibre CPE
- CAT 5E Ethernet cable
- TP-Link Archer C80 1.0
- Firmware 1.10.0
I recently go a speed upgrade to 200/200Mbps but haven’t been able to get the full speeds as my Archer C80 WAN port only runs at 100Mbps. It is running in Router Mode. If I connect a laptop directly to the CPE via the same Ethernet cable I can get the full 200/200Mbps.
When logging into tplinkwifi.net and navigating to Advanced > Network > Internet > Internet Port Negotiation Speed Setting, it is set at Auto Negotiation and the LAN light on the CPE is green. If I navigate to Network Map > Archer C80 > Ethernet Status, the Internet WAN port reads as 100Mbps/Full Duplex. If I change the Internet Port Negotiation Speed Setting to 1000Mbps/Full Duplex the internet drops and the CPE light turns orange. If I navigate back to Ethernet Status, the Internet WAN port is now greyed out.
For the life of me can’t figure out a way to get it working. Any help would be greatly appreciated.

@Kevin_Z Thanks, I resolved an issue. I got a cable from the router's package and replaced the one from my ISP and it works perfectly now.
