How to Set Up an Ethernet Cable on a Laptop Without an Ethernet Port
Setting up an Ethernet cable on a laptop without an Ethernet port usually requires the use of a USB-to-Ethernet adapter (also called a USB-to-Ethernet converter or USB network card). Here are the detailed setup steps:
1. Prepare the hardware
Ethernet cable: Make sure you have an Ethernet cable available (usually Cat5e or Cat6) to connect your laptop to your router or modem.
USB-to-Ethernet adapter: Purchase a USB-to-Ethernet adapter for your laptop. This adapter can be purchased at electronics stores or online at a relatively affordable price and is suitable for temporary or short-term use needs.

2. Connect the hardware
Connect the adapter: Plug one end of the USB-to-Ethernet adapter into the USB port of your laptop.
Connect the Ethernet cable: Plug one end of the Ethernet cable into the LAN port of your router (make sure it is not the WAN or Internet port) and the other end into the Ethernet port of the USB-to-Ethernet adapter.
3. Configure network settings
Auto-connect: Modern operating systems (such as Windows 10/11 and macOS) are usually able to automatically recognize and connect to Ethernet networks without additional configuration. Once the cable is connected, you may be automatically prompted to select a network and enter a password (if the network is protected).
Manual settings:
MacOS:
Open System Preferences and click Network.
Find and click Ethernet in the list of network connections on the left (you may need to click the lock icon in the lower left corner to unlock the permission to change).
Configure IPv4 to Use DHCP, then click Apply to save the settings.
Windows:
Right-click the network icon in the system tray and select Open Network and Internet Settings.
Click Change Adapter Options, find and right-click the newly appeared Ethernet connection (usually named Local Area Connection or something similar), and select Properties.
In the window that pops up, select Internet Protocol Version 4 (TCP/IPv4), then click Properties.
Select Obtain an IP address automatically and Obtain DNS server address automatically, then click OK to apply the settings.
4. Test the connection
Open a browser: Try opening a web page or using other network services to test whether the connection is successful.
Check the network connection status: In the network settings of the operating system, check the status of the Ethernet connection to make sure it is activated and has obtained the correct IP address.
5. Common Problem Solving
Unable to obtain IP address: Try restarting the router and computer to check whether the router is correctly configured and the DHCP service is turned on. If you use manual configuration of IP address, please make sure that the IP address, subnet mask, default gateway, etc. are set correctly.
Slow network connection: Check whether the router is far away from the laptop, causing signal attenuation. Restart the router and computer to clear possible network cache or failure. Check whether there are other devices taking up a lot of bandwidth, such as downloading large files or playing online games.
With the above steps, you should be able to successfully connect a laptop without an Ethernet port to an Ethernet network. Please note that different operating systems and hardware may vary, so in actual operation, adjustments may need to be made according to specific circumstances. If you encounter complex problems that cannot be solved, it is recommended to seek help from professional technicians.
