The Physical Connection
2. Cables, Cables Everywhere, But Which Ones Actually Work?
Lets start with the basics. Your network cables are like the arteries of your LAN. If they're damaged or of poor quality, they can significantly impede data flow. Are you still using those old Cat5 cables you found in a box from 2005? It might be time for an upgrade. Cat5e or Cat6 cables are recommended for Gigabit Ethernet, which is pretty much the standard these days. Using older cables can severely limit your network's speed, even if all your devices are capable of much faster speeds.
Inspect your cables for any visible damage. Look for bends, kinks, or frayed ends. A damaged cable can cause intermittent connectivity issues and significantly reduce your network speed. It's like trying to drink through a straw that's been chewed on — not a pleasant experience, and certainly not efficient.
Also, ensure your cables are properly connected to your devices. A loose connection can cause signal degradation and slow down your network. Make sure the cables are securely plugged into your router, switch, and computers. It sounds simple, but it's a common mistake that's easily overlooked.
Finally, check the length of your cables. While Ethernet cables can theoretically run up to 100 meters (328 feet), longer cables can experience signal loss, especially if they're not high-quality. If you need to run a cable over a long distance, consider using a signal booster or switch to maintain optimal performance.
