One of the easiest ways to improve Ethernet speed and performance is to upgrade your equipment to support higher data transfer rates. You should check if your devices cables routers modems switches and hubs are compatible with the latest Ethernet standards such as Gigabit Ethernet (1000 Mbps) or 10 Gigabit Ethernet (10 Gbps). You should also check if your equipment supports features such as Quality of Service (QoS) which prioritizes certain types of traffic over others or Power over Ethernet (PoE) which delivers power and data over a single cable.
