Advantages of Wired Networks

The Advantages of Wired Networks include faster internet speeds and a more stable connection compared to wireless networks. 89% of businesses still use wired connections in their offices. If you’re looking for reliability and speed, then wired networks are the way to go. Here are some benefits of opting for a wired network:

  • Faster internet speeds: With a wired connection, data travels directly from the source to your device without any interference or lag. This results in faster download and upload speeds, making it perfect for businesses that require quick access to large files.

  • More secure: Wireless networks can be easily hacked into by cybercriminals who use them as entry points into your company’s sensitive data. Wired networks are less vulnerable to this type of security breach because they require physical access to your network cables.

  • Lower latency: Wired networks have lower latency than wireless connections. Latency is the time it takes for data to travel from one point on a network to another. A low latency means quicker response times and better performance.

However, there are also drawbacks associated with using a wired network such as limited mobility due to being tethered to cables and difficulty expanding or moving the network infrastructure once installed. Despite these disadvantages, many businesses still opt for wired connections because of their superior reliability and security features.

Setting up a Wired Network

Now it’s time for you to set up your own wired network, and don’t worry, it’s easier than you think.

First things first, you need to ensure that your devices are compatible with the type of network cable you plan on using. Ethernet cables are the most common type used for wired networks, and come in different categories based on their performance capabilities.

Category 5e (Cat5e) is suitable for most home networks, while Category 6 (Cat6) offers higher speeds and better performance for larger networks.

Once you’ve determined the compatibility of your devices with the network cable, it’s time to compare costs. While wireless networks may seem more convenient, they can also be more expensive due to the need for additional equipment such as routers and adapters.
