What are the primary factors that affect Ethernet speed?

The primary factors that affect Ethernet speed include the type of Ethernet cable used, the quality of the cable, and the distance between the device and the router. The most common types of Ethernet cables are Cat5, Cat5e, Cat6, and Cat7, each with its own maximum speed limit. For example, Cat5 cables have a maximum speed limit of 100 Mbps, while Cat7 cables can support speeds of up to 10 Gbps. The quality of the cable is also crucial, as a low-quality cable can lead to signal degradation and reduced speeds.

In addition to the cable type and quality, the distance between the device and the router can also impact Ethernet speed. The farther the device is from the router, the weaker the signal becomes, which can result in slower speeds. Other factors such as network congestion, interference from other devices, and the quality of the router itself can also affect Ethernet speed. To minimize these factors, it is essential to use high-quality cables, keep devices close to the router, and use a high-quality router that can handle multiple devices and high-speed connections.
