A 2.5GbE switch is worth buying in Witbank when multiple local devices already support multi-gig Ethernet and regularly move large files. It does not make an internet service faster than its plan, router or fibre port. The supplied factpacks do not verify a suitable switch or price.
Map every port in the path
List the router, PCs, NAS, access points and uplink speed. Check each Ethernet controller and cable category. A 2.5GbE link can help workstation backups or game transfers from compatible local storage, but ordinary online gaming usually benefits more from stable latency and low packet loss than extra switch throughput.
Test direct Ethernet to the router and copy a large file between the two fastest devices. If neither exceeds gigabit performance, find the limiting port or storage before buying. The Cudy WR3600E router is a verified reference at R766, but its current port specifications must be checked against the proposed topology rather than assumed.
For a switch, compare documented port speeds, switching capacity, managed features, cooling, power use, mounting, warranty and local delivery support. Keep it ventilated and label every cable. Avoid buying multiple unknown adapters merely to make speed labels match. Choose multi-gig equipment as one compatible end-to-end path, and retain reliable gigabit hardware when the measured workload cannot use more.
