However, if you are using a static IP address or encountering connectivity problems, you might need to configure the network settings manually. In Windows, go to Settings > Network & Internet > Change adapter options. Right-click on your Ethernet adapter and select "Properties." Double-click on "Internet Protocol Version 4 (TCP/IPv4)." Select "Use the following IP address" and enter the required information:
- IP address: A unique IP address within your network's subnet (e.g., 192.168.1.100).
- Subnet mask: Usually 255.255.255.0.
- Default gateway: The IP address of your router (e.g., 192.168.1.1).
- Preferred DNS server: The IP address of your preferred DNS server (e.g., 8.8.8.8, Google's public DNS).
- Alternate DNS server: The IP address of an alternative DNS server (e.g., 8.8.4.4).
In macOS, go to System Preferences > Network. Select your Ethernet adapter and configure the settings.
Testing the Connection: After configuration, test your internet connection. Open a web browser and try to access a website. If you can browse the internet, your LAN connection is working correctly. If not, revisit the troubleshooting steps.

Sometimes, the solution isn’t as straightforward as a cable connection. More involved troubleshooting might be necessary.

Firewall Interference: Your firewall, whether it's the built-in Windows Firewall, macOS Firewall, or a third-party firewall, can sometimes block network traffic. Temporarily disable your firewall to determine if it's interfering with your LAN connection. Remember to re-enable your firewall after testing.
IP Address Conflicts: If another device on your network is using the same IP address as your laptop, you'll experience connectivity issues. To resolve an IP address conflict, either configure your laptop to obtain an IP address automatically via DHCP, or manually assign it a unique static IP address.
Router Firmware Issues: Outdated router firmware can sometimes cause connectivity problems. Check your router manufacturer's website for firmware updates and follow the instructions to update your router's firmware.
DNS Server Problems: DNS (Domain Name System) servers translate domain names (e.g., google.com) into IP addresses. If your DNS server is down or experiencing problems, you won't be able to browse the internet. Try using a different DNS server, such as Google's public DNS servers (8.8.8.8 and 8.8.4.4) or Cloudflare's DNS servers (1.1.1.1 and 1.0.0.1).
Hardware Malfunctions: In rare cases, the Ethernet port on your laptop or router might be faulty. If you suspect a hardware malfunction, try connecting your laptop to a different Ethernet port on the router or connecting a different device to the same Ethernet port on your laptop. If the problem persists, contact a qualified technician.
