Hardwiring Your Home for Ethernet

Hardwiring Your Home for Ethernet


Installing Ethernet cabling throughout your home is one of the best investments you can make for your home network. An Ethernet wired network provides faster, more reliable connectivity compared to WiFi and allows you to connect devices like smart TVs, game consoles, and computers directly to your router or network switch to maximize performance.

In this comprehensive guide, I will walk you through everything I learned about planning, installing, and setting up hardwired Ethernet in my home. Whether you want to wire a few rooms or every corner of your house, this guide will provide the knowledge you need to get the job done.

Reasons to Install Ethernet Cabling

Here are some of the key benefits of installing Ethernet cabling in your home:

Faster Speeds

Ethernet provides faster maximum speeds compared to WiFi. Gigabit Ethernet offers speeds up to 1000 Mbps, far greater than the maximum 480 Mbps typically delivered by the latest WiFi 6 routers. This means faster file transfers, smoother video streaming, and lag-free online gaming.

Lower Latency

The wired connection of Ethernet leads to consistently lower latency versus WiFi. This reduced lag is vital for competitive online gaming and activities like video calls and conference calls.


Ethernet offers a more reliable connection that is not subject to interference from appliances, walls, and other WiFi networks like wireless can be. The result is a solid, dependable connection anywhere you install an Ethernet jack.


Connecting devices via Ethernet removes the frustrations of troubleshooting WiFi issues or weak signal areas. It just works!


Wired Ethernet provides an excellent foundation for future network upgrades. As your internet speeds increase over time, Ethernet will be able to keep up whereas WiFi may not.

Planning Your Home Ethernet Cabling

Careful planning is crucial when installing Ethernet cables throughout your home. Here are some key steps:

Map Out Your Home

Draw up plans showing an overhead view of each room in your home. Note any potential challenges like concrete walls or lack of access to parts of your home. This map will act as your wiring guide.

Determine Device Locations

Mark on your map where devices like desktop PCs, smart TVs, and game consoles are located in each room. These are good candidates for wired connections.

Pick Network Hardware Locations

Choose central locations for your network hardware like your router, network switch, and cable modem. Basement, utility closets, and the back of a closet are common options.

Plan Cable Runs

Outline the paths where you'll run cables between devices, rooms, and network hardware. Check for access through walls, attics, basements, etc. Shorter runs are ideal.

Allow Extra Cabling

For each cable run, add 20-30% extra length to allow for mistakes, rerouting, and future flexibility. It's much easier to coil extra cable than to run out!

Ethernet Cabling Options

The type of Ethernet cable you choose will depend on your bandwidth needs and budget. Here are the key options:

Category 5e

Cat 5e cables support speeds up to 1000 Mbps which covers gigabit Ethernet. It provides the best value for most home networking uses.

Category 6

Cat 6 cables can handle speeds up to 10 Gbps and are future-proof should you upgrade to a 10 gigabit network. The premium price may not be worthwhile for homes.

Category 6a

Cat 6a is similar to Cat 6 but with greater shielding against electromagnetic interference (EMI). It's overkill for homes but useful in industrial settings.

For most homes, I recommend using Cat 5e cables, as they provide the right mix of performance and affordability.

Choosing Solid vs. Stranded Cable

Ethernet cables come in solid and stranded varieties:

For home use, I prefer stranded cable. It holds up better when pulled through walls and ceilings and is less likely to break down over years of use. The extra flexibility is worth the small price premium.

Buying Bulk Ethernet Cable

To save money on your structured wiring project, I recommend buying Ethernet cable in bulk spools rather than pre-made patch cables. Here are some tips:

Terminating your own Ethernet cables is easy with some practice. Buying bulk cable shipped to your door saves a ton over pre-made patch cables.

Installation - Running Cables

Now comes the fun part - it's time to start running cable! Here are some best practices I learned:

Label Everything

Label both ends of each cable run with masking tape indicating the room destinations. This avoids confusion down the road.

Use Wall Plates

Install wall plates with Ethernet jacks in rooms instead of just pulling cable through holes. This looks much cleaner.

Follow Building Codes

Research local building codes so your work passes inspection. Firestops are often required when running cable through walls.

Fish Wire is Your Friend

Use fish tape, glow rods, or maze runners to pull cables through walls. Watch out for insulation and other obstructions.

Attics and Basements

Route cables through attics and basements whenever possible. It's much easier than cutting drywall!

Get Help

For tricky cable runs, don't be afraid to get a helper to feed the cable while you pull or vice versa. Much easier with two people.

With good planning and some patience, the cable pulling process isn't too difficult. Just take it slow and be careful not to kink or damage the cable.

Installing the Network Panel

The network panel acts as the central hub that connects all your Ethernet runs together. Here are some tips:

Choose a Location

Pick an out-of-the-way spot like a structured media enclosure, basement, or closet for your panel.

Panel Size

Size your panel to accommodate all your planned Ethernet runs with extra room to spare. I used a 24 port panel which was overkill for my needs.

Use Patch Panels

Patch panels allow you to easily connect devices by plugging short patch cables between ports. Much more convenient than directly terminating runs.

Label Ports

Label each port on the patch panel with its corresponding room or location. This avoids future confusion.

Test Connections

Use a cable tester to validate all your runs after installing the panel. Catch any issues now before finishing the walls.

The network panel takes more planning but really ties your structured wiring together. Do it right the first time!

Installing Network Switches

The other key component of your network hardware is the Ethernet switch:

Gigabit Switch

Choose a gigabit switch with enough ports for your wired connections. Prioritize switches with:10 Gbps uplink for future-proofing.

PoE Switch

Consider a Power over Ethernet (PoE) switch to provide power to devices like WiFi access points, cameras, and phones over the Ethernet cable.

Managed vs Unmanaged

Managed switches allow for more advanced features like VLANs and link aggregation. Unmanaged are plug-and-play.

Mounting Options

Look for rackmount, wall mount, or desktop form factors to match your space. Cooling fans are a nice bonus.

For most homes, an 8 or 16 port unmanaged Gigabit switch will get the job done nicely. Connect your switch to your router, modem, and network panel to tie everything together.

Testing and Troubleshooting Your Network

As a final step, be sure to thoroughly test your new home Ethernet network. Here are some tips:

Verify Connectivity

Check that devices get IP addresses and can communicate over the network. Ping devices to test basic connectivity.

Validate Speeds

Use online speed tests and file transfers to verify you're getting your full ISP download and upload rates over the wired connections.

Check All Ports and Runs

Systematically go through all ports and cable runs, testing each one works as expected. Better to find any issues now!

Tone and Probe

If a cable isn't working, use a tone and probe kit to trace and isolate the faulty run. Super handy for troubleshooting.

Get Professional Help

For tricky issues, don't be afraid to hire a low voltage electrician or network technician to assist with diagnosing and fixing problems.

Patience and diligence during testing will help identify and resolve any weak points in your new network infrastructure.

Final Thoughts

Installing Ethernet throughout my home required careful planning, research, and plenty of labor. But all the hard work was worth it in the end! The investment provided my family with a high-speed wired backbone that will suit our needs for years to come.

The knowledge I gained along the way will also allow me to wire any future homes much more efficiently. If you're considering taking on a similar project in your own home, I hope this guide provides a helpful starting point and overview of the entire structured wiring process.
