in-depth: How to Run Ethernet Cables to Your Router and Keep Them

Upgrade your home network with a faster, more stable connection by running Ethernet cables. Wired connections offer superior performance for tasks like optimizing router placement, setting up mesh backhaul, or connecting an EV charger. This guide will show you how to select the right cables, plan your route, and neatly conceal them for both efficiency and aesthetics.

Before You Start: Essentials and Speed Considerations

To begin, gather your tools and understand network basics. You'll need Ethernet cables (Cat 6a or Cat 7 for main runs are recommended), an Ethernet switch (optional, if more ports are needed), cable management items like ties, sleeves, and adhesive clips, and a measuring tape. For advanced hiding, consider fiberglass snake rods, brush wall plates, bulk cable, and termination tools (punch-down tool, keystone jacks, wall plates).

Remember, your internet speed is capped by your service provider. While faster internal network transfers are possible with higher-rated gear, ensure all components—router, cables, switches, and devices—match your desired speed. The slowest link in your setup will always dictate performance.

Choosing the Right Ethernet Cables

Select cables for optimal performance and durability:

• Category (Cat) Rating: Cat 5e/6 (up to 1 Gbps) are often sufficient. Cat 6a/7 (up to 10 Gbps) are recommended for main runs for future-proofing, with minimal cost difference. Cat 7a/8 (40 Gbps) are usually overkill and more expensive.
• Shielding: UTP (Unshielded Twisted Pair) is preferred for most homes; it's flexible and durable. STP/FTP (Shielded/Foiled Twisted Pair) is only needed near strong electrical interference, but is less flexible and more fragile.
• Cable Shape: Avoid flat cables due to their proneness to interference and damage. Stick to standard round cables.
• Manufacturer: Choose recognized brands.

Do You Need an Ethernet Switch?

If your router lacks sufficient Ethernet ports, an unmanaged plug-and-play Ethernet switch is an easy solution. It expands one port into many, requiring no complex setup. Choose a 5-port or 8-port switch with a few spare ports for future expansion. Bandwidth is shared among ports. A managed switch is only needed for advanced network configurations like traffic prioritization.

Planning Your Cable Runs & Best Practices

Careful planning ensures a tidy and functional setup. Always label both ends of each Ethernet cable, especially for multiple lines or concealed runs, to save troubleshooting time and aid identification.

1. Map Route: Visualize the cable path from start to finish.
2. Avoid Kinks: Sharp bends damage cables; use gentle curves.
3. Bypass High-Traffic Areas: Place cables along walls, not under furniture or in doorways, to prevent damage.
4. Minimize Interference: Keep cables away from strong electrical sources.
5. Use Cable Management: Employ ties, sleeves, or organizers to group and secure cables.

How to Hide Ethernet Cables

Choose a method that fits your home:

1. Along the Baseboard: Tuck cables into baseboard channels/recesses, securing with adhesive or nailed clips. For room-to-room, consider drilling a small wall hole.
2. Under Carpet or Rug: Run cables beneath carpets, tight against baseboards. Use a dedicated floor cord protector if crossing doorways.
3. Using Cable Raceways (Trunking): Attach paintable channels to walls that neatly enclose cables, blending for a professional look.
4. Using Crown Molding: Incorporate cables into decorative crown molding (coving) for a concealed run. Plan discreet cable entry/exit points.
5. Behind the Wall or Under the Floor (Most Advanced): The neatest finish but invasive, requiring tools and caution against electrical/water lines. Use fiberglass snake rods for guiding and brush wall plates for finished openings. For bulk cable, use a punch-down tool, keystone jacks, and wall plates. Pro Tip: Include a pull string with hidden cables for easier future changes.

Hiding Switches and Power Strips

Conceal networking hardware in media cabinets, behind TVs, or within cable management boxes to maintain a completely tidy setup.

Next Steps

If wired solutions aren't universally practical, explore wireless network improvements. Check guides on making Wi-Fi faster, fixing Wi-Fi issues, or finding the best mesh routers, Wi-Fi routers, or extenders.

FAQ

Q: Do I really need to upgrade from Cat 5e or Cat 6 cables? A: While Cat 5e or Cat 6 cables suffice for most home internet speeds up to 1 Gbps, upgrading to Cat 6a or Cat 7 for primary runs offers future-proofing for faster internet (up to 10 Gbps) or internal transfers, often with minimal extra cost.

Q: Are flat Ethernet cables a good option for hiding? A: The source advises against flat Ethernet cables. They are more prone to interference and can be less durable than standard round cables, potentially leading to connectivity problems.

Q: What if my router doesn't have enough Ethernet ports? A: Use an unmanaged plug-and-play Ethernet switch. Connect it to one of your router's ports to gain multiple new ports. It's recommended to choose a switch with a few spare ports for future expansion.
