How to Improve Internet Speed with the Right LAN Cable

In today’s fast-paced digital world, reliable and high-speed internet access has become indispensable. While many factors can influence your internet speed, choosing the right LAN (Local Area Network) cable is often overlooked yet plays a crucial role in optimizing your network performance.

Cable Category

The category of the LAN cable determines its maximum supported bandwidth and speed. Higher category cables offer faster speeds. For optimal performance, consider using Cat5e, Cat6, or Cat6a cables. Cat5e cables support speeds up to 100 Mbps, Cat6 cables up to 1 Gbps, and Cat6a cables up to 10 Gbps.

Cable Length

The length of the LAN cable can also affect internet speed. Longer cables introduce signal attenuation, which can lead to reduced speeds. For optimal performance, use the shortest cable length possible for your needs. Generally, cables shorter than 100 meters (328 feet) are recommended.

Connector Type

The type of connector on the LAN cable also matters. RJ45 connectors are commonly used and support Gigabit Ethernet speeds. However, for even faster speeds, consider using RJ45 connectors with gold-plated pins, which provide improved signal transmission.

Conductor Material

The conductor material of the LAN cable influences its electrical properties. Copper conductors are generally better than aluminum conductors, as they offer lower resistance and higher conductivity. For the best performance, choose cables with high-quality copper conductors.


Shielding in LAN cables protects against electromagnetic interference (EMI), which can disrupt signal transmission. Shielded cables are typically wrapped in a foil or braid to minimize interference. Use shielded cables in areas where EMI is present, such as near wireless devices or fluorescent lighting.

Cable Termination

Proper cable termination is essential for optimal performance. Ensure that the cables are correctly terminated with the appropriate connector and that the pins are firmly seated. Avoid poorly crimped or damaged plugs, as they can cause signal loss or intermittent connectivity.

Choosing the Right Cable

To choose the right LAN cable for your needs, consider the following factors:

Bandwidth requirements: Determine the bandwidth required for your applications and choose a cable category accordingly.

Cable length: Use the shortest cable length possible to minimize signal attenuation.

Connector type: Opt for RJ45 connectors with gold-plated pins for faster speeds.

Conductor material: Choose cables with high-quality copper conductors for better performance.

Shielding: Consider shielded cables if EMI is present in your environment.

Termination: Ensure proper cable termination to maintain signal integrity.

By following these guidelines, you can choose the right LAN cable to improve your internet speed and ensure a reliable and efficient network connection.
