Ethernet cables have been a staple in networking for decades, connecting our computers, gaming consoles, and smart devices to the internet with unmatched reliability. Despite their importance, several myths about Ethernet cables have persisted over the years. In this blog, we’ll debunk some of the most common misconceptions and help you understand the facts behind these myths.

Myth 1: Expensive Ethernet Cables Are Always Better

Many people believe that the higher the price tag, the better the Ethernet cable. While price can sometimes reflect quality, this isn’t always true for Ethernet cables. Most mid-range cables perform just as well as expensive ones if they meet the required standards (like Cat 6 or Cat 7).

Fact: Performance depends on the category and build quality, not the price. A well-made Cat 6 cable from a reliable brand can provide excellent performance at a fraction of the cost of premium brands.

Myth 2: Ethernet Cables Don’t Wear Out

It’s a common misconception that Ethernet cables last forever. While they’re durable, they’re not indestructible. Factors like frequent bending, exposure to heat or sunlight, and poor handling can degrade their performance over time.

Fact: Over time, cables can suffer from wear and tear, resulting in slower speeds or intermittent connectivity. Replacing old or damaged cables can restore network performance.

Myth 3: All Ethernet Cables Are the Same

Some people assume that all Ethernet cables are interchangeable. However, Ethernet cables come in different categories, each with varying speeds, bandwidths, and shielding.

Fact: For example, a Cat 5 cable can’t handle gigabit speeds as efficiently as a Cat 6 or Cat 7 cable. Choosing the right cable category is essential for maximizing your network’s potential.

Myth 4: Ethernet Is Always Better Than Wi-Fi

While Ethernet is often faster and more reliable, this isn’t universally true. Modern Wi-Fi technologies, like Wi-Fi 6 and Wi-Fi 7, offer impressive speeds and convenience that sometimes-rival Ethernet connections.

Fact: Ethernet is better for scenarios requiring consistent, low-latency performance, such as gaming and video streaming. However, Wi-Fi might be more practical for mobile devices and general home use.

Myth 5: Thicker Cables Are Always Faster

Some believe that a thicker Ethernet cable automatically means faster speeds or better performance. Thickness often relates to the cable’s outer insulation and shielding, not its internal capabilities.

Fact: The internal wiring and category rating (e.g., Cat 6, Cat 7) determine speed and performance, not the cable’s thickness. Always check the cable’s specifications instead of judging by its appearance.

Myth 6: Shielded Cables Are Necessary for Home Networks

Shielded Ethernet cables (STP) are designed to reduce interference in environments with lots of electrical noise. Many people think these are essential for every setup.

Fact: For most home networks, unshielded twisted pair (UTP) cables work perfectly fine. Shielded cables are only necessary in industrial settings or places with significant interference.

Myth 7: Longer Cables Always Cause Speed Loss

There’s a widespread belief that longer Ethernet cables drastically reduce speed. While it’s true that signal degradation can occur over long distances, modern cables are designed to handle this effectively.

Fact: Ethernet cables can run up to 100 meters (328 feet) without noticeable speed loss, as long as they meet the proper standards. If you’re running cables over extreme distances, consider signal boosters or switches.

Myth 8: Ethernet Cables Are Difficult to Install

Many people shy away from using Ethernet cables because they think installation is complicated and requires professional help.

Fact: Installing Ethernet cables can be straightforward with a little guidance. Tools like cable clips, crimpers, and pre-made cables make the process simple for most users. Plenty of online tutorials can walk you through DIY installations.

Myth 9: You Need the Latest Category for Every Device

It’s easy to think that upgrading to the latest cable category, like Cat 8, is necessary for optimal performance.

Fact: Most home networks and devices don’t require Cat 8 cables. Categories like Cat 5e or Cat 6 are sufficient for typical internet speeds and usage. Choose a cable that matches your current and near-future needs.

Conclusion

Ethernet cables are a vital part of any network, but misinformation can lead to unnecessary spending or poor performance. Understanding these myths can help you make informed decisions when setting up or upgrading your network. Remember, the right Ethernet cable depends on your specific needs, not flashy marketing or high price tags.
