“How to Check Your Ethernet Cable's Speed and Diagnose Network Slowdowns” — what this page in the network covers. Knowing the speed rating of your Ethernet cable is crucial for diagnosing network performance issues. Many home and office slowdowns stem from using older cable categories that can't support modern internet speeds. By checking the cable's category—printed on the jacket—you can determine its maximum data rate, such as 100 Mbps for Cat5 or 10 Gbps for Cat6a. This matters because even if you pay for gigabit internet, a Cat5 cable will bottleneck your connection to a fraction of that speed.
Upgrading to a higher-category cable is often a simple and inexpensive fix. The original guide explains how to read cable markings and test real-world speeds, helping you identify whether your cable is the culprit. Check your cable today—it might be the easiest upgrade you can make. This listing links straight to the original page, where the content is available in full.
