Wired Network Setup
A wired network setup provides stable, low-latency connectivity compared to wireless alternatives. Proper configuration requires selecting appropriate hardware, specifically Routers, Switchs, and cabling infrastructure.
Cabling Infrastructure
The physical layer of a wired network relies on twisted-pair copper cabling. Selection depends on bandwidth requirements, distance, and cost-effectiveness.
Ethernet Cable Categories
- Cat 5e: Supports up to 1 Gbps at 100 MHz. Sufficient for most standard home broadband connections.
- Cat 6: Supports up to 10 Gbps at 250 MHz (up to 55 meters). Recommended for future-proofing and higher throughput.
- Cat 6a: Supports 10 Gbps at 500 MHz (up to 100 meters). Reduces crosstalk and interference.
- Cat 7/7a: Shielded cables supporting higher frequencies; often overkill for residential use.
- Cat 8: Supports 25 Gbps or 40 Gbps at 2000 MHz. Designed for data centers and short-distance high-speed links.
Selection Criteria
- ISP Speed Alignment: Match cable category to ISP plan. Cat 5e is the bottleneck for >1 Gbps plans; upgrade to Cat 6 or higher.
- Cost-Effectiveness: Avoid over-specifying. Cat 6 is generally the sweet spot for performance vs. cost in modern homes.
- Interference: Shielded cables (STP/FTP) are necessary in environments with high electromagnetic interference.

Hardware Configuration
- Router: Acts as the gateway between the local network and the ISP.
- Switch: Expands the number of available LAN ports. Ensure switches support Gigabit or 10-Gigabit speeds depending on cabling.
- NIC (Network Interface Card): End-device hardware must support the negotiated speed of the cable and switch.
