How to connect an ethernet cable to a PC
Though the world is moving towards wireless connectivity, there are still several good reasons to remain connected to the internet through an ethernet cable.
The physical connection between the router and your PC through an ethernet cable provides higher data speeds and is more reliable.
Further, it allows you to enjoy internet connectivity in areas where Wi-Fi cannot reach.
Connecting to your Modem and Router:
- Connect the modem to the internet cord, a cable, fiber optic line, or a DSL from your wall.
- Now, connect the modem to your router if you are using a separate wireless router. Take an ethernet cable and connect the modem to the router’s internet port which may be labeled as WAN, Internet, WLAN, or UpLink. You can skip this step if you are not using a separate wireless router.
- Ensure that lights labeled as POWER, US/DS, and INTERNET/ONLINE are solid. The blinking of these lights indicates that the modem is not connected to the internet. Contact your service provider for assistance in such a case.
- Now, connect one end of the ethernet cable to the router/modem port labeled as LAN. Sometimes, the port is also named ETHERNET followed by numbers.
- Next, connect the other end of the cable to your computer’s ethernet port that you may find either on the left or right side of the laptop. In all-in-one monitors, it’s generally present on the backside.

How to connect a PC to Wi-Fi without Ethernet
A wireless network connection is becoming much more preferable by people due to its convenience.
In addition, you may not experience any considerable difference in the internet speed while transferring audio, video, and data.
However, in moving large amounts of data, the wireless connection may not be as effective as the ethernet connection.
Try these easy and affordable options if you also want to avoid ethernet cables in your network connections.
Get a Wi-Fi adapter:
Investing in a Wi-Fi adapter can be the best way to connect to a wireless network.
Some desktop PCs and laptops have in-built wireless adapters in them, while for others, you have to buy them.
These affordable devices offer high internet speed and you need not worry about battery life too.
Computers manufactured in the last decade have in-built Wi-Fi adapters. If that is the case, you have the hardware ready with you.
Even if you have a built-in Wi-Fi adapter, you can consider buying a new one, as most built-in adapters are low in quality.
They may create issues while working as they lack the latest technology. However, before purchasing a new one always check for existing Wi-Fi hardware.
Step 1: Type device manager in the search box on the lower right side of your screen. You will see the device manager in the results. Click on it.
Step 2: In the device manager results, you will see “Network Adapters.” Click on it, and it will expand giving you a list of network devices.
Step 3: Amazon the results and you may see a Wi-Fi adapter. If you have one, it verifies that your computer has some Wi-Fi adapter.
1: Find the wireless icon on the menu bar at the top of the screen.
2: You can verify through the system information screen by clicking on the Apple logo and selecting “system information.”
3: Find Wi-Fi under the network settings, and it will show you card information if it is present there.
It is a card that you can add internally. While buying a PCI card, you must invest in the fastest and latest wireless technology in the market.
It is the most versatile option, as you can use it via a USB port with any system. A USB plug-in works with both desktops and laptops equally.
Simply plug in the USB device, and you have access to the wireless network. Though the speed and technology of USB cannot beat that of PCI cards, it is still a fast option for most users.
Deciding whether you should have a PCI card or a USB plug-in can be confusing. You must know which interface is suitable for you.
The significant advantage of USB is that you can use it with multiple devices. However, if you need speed, you must go for PCI and go for USB plug-in if convenience is your priority.
Once the adapter is delivered to your place, follow the instructions with the device. Most devices are plug-in-and-play devices. If there is no instruction manual, look for similar videos on YouTube.
Once you install the hardware, the software may be installed automatically. There must also be a CD/DVD or any weblink to install the software.
Remember, whenever you use this adapter, you must access a wireless network in your home. You must also know the name and password of the network but only once.
Once the device is set up, it automatically attempts to connect whenever it turns on.
Sometimes, you have the proper hardware, but it does not connect for some reason. One common reason is that the Wi-Fi button is turned off.
All systems have a Wi-Fi button which you must turn ON before connecting to the internet.
If you cannot find this button, search the internet for the make/model you use and then turn it ON.
However, you should also remember that not all systems have this type of system.
Here are some steps for enabling Wi-Fi in different systems:
- Go to the Windows button on your desktop (lower left corner)
- Search for “Settings.”
- Click on “Network and Internet” in the Settings search results.
- Click on Wi-Fi. An ON/OFF button appears. You can click on it to turn the Wi-Fi ON.
- Once you do that, connect to the network with the help of the network name and password.
- Search for the Wi-Fi button on the menu bar
- Select it and click on Wi-Fi On.
- Select the network and connect to it through the name and password.
