Hello @William_Torrez ,

Welcome to our community.

Here are some steps that will help you troubleshoot the Ethernet port speed:

1. Check Ethernet Lights
• Verify if the Ethernet light on the router is lit up when you connect the cable. If not, it indicates a potential problem with the Ethernet cable, LAN port on the router, or the Ethernet port on your wired client device.
• Try using a different Ethernet cable (ensure it's Cat5e or above), switch to another LAN port on the router, and test with a different wired client device.

2. Check Internet Port Negotiation Speed
• Log in to the router's web management interface at http://tplinkwifi.net or http://192.168.0.1
• Navigate to Advanced > Network > Internet > Internet Port Negotiation Speed Setting
• Try setting the speed to "1000Mbps Full Duplex" or "Auto Negotiation" to ensure gigabit speeds are enabled
• Apply the settings and test again

3. Verify Cable Quality
• Ensure all Ethernet cables are genuine Cat5e or higher quality cables. Some counterfeit or damaged cables may not support gigabit speeds properly.
• Try different cables from different manufacturers if possible.

4. Reboot Devices
• Reboot both your wired client device and the router. Sometimes a simple restart can resolve connectivity and negotiation issues.

5. Check IP Configuration
• Ensure that the wired client device is set to obtain an IP address automatically.
• For Windows: Go to the Network Connection Details page and verify that "DHCP enabled" is set to "Yes."
• For Mac: Navigate to Network > Advanced and confirm that "Configure IPv4" is set to "Using DHCP."

6. Test with Another Device
• Connect another device to the router using the same Ethernet cable and port. If the Internet works at gigabit speeds on the other device, the issue lies with the initial device's network adapter.

Regarding the signal issues:
If you're also experiencing WiFi signal problems, please let me know more specific details about what kind of signal issues you're experiencing (e.g., weak signal, devices dropping, slow speeds) so I can provide targeted troubleshooting steps.
