Wi-Fi gets most of the attention, but a wired connection is still the most reliable way to link a desk, a console, a TV or a mesh node. This category covers the physical side of a home network, from choosing cable to tidying it into a patch panel.
Why wire at all
Ethernet gives you consistent speeds, low latency and no interference from neighbors or walls. Even a few well-placed runs can make a big difference, especially for wired backhaul between mesh nodes or access points.
Ethernet cable categories
Cat5e, Cat6, Cat6a and higher categories differ in the speeds they support, how far they can carry them, and how they’re built. We explain what each category realistically supports in a home, when a higher category is worth paying for, and why labels on cheap cable aren’t always trustworthy. We also cover flat versus round cable, solid versus stranded conductors, and connector types.
Running Ethernet through a house
Getting cable from one room to another is often the hardest part of a wired project.
Planning the route
We explain how to plan runs in existing homes and new builds, how to pick a central location for your equipment, and when outdoor conduit is needed.
Cable ratings and codes
Cable run inside walls, ceilings or between floors should have the right rating for the space, such as CMR riser or CMP plenum where required. We point out where local building and electrical codes apply, and we recommend a licensed electrician for anything involving mains power, outlets or electrical panels.
Termination, keystones, patch panels and racks
Once cable is in the wall, it needs clean terminations. We cover T568A and T568B wiring, keystone jacks, wall plates and patch panels, plus how to size a small network rack for a closet or utility room.
Network switches and PoE
A switch adds wired ports where you need them, and Power over Ethernet lets one cable carry both data and power to access points, cameras and other devices. We compare managed and unmanaged switches, explain PoE standards and power budgets, and clear up common mix-ups between switches, hubs, splitters and routers.
When you can’t run cable: powerline and MoCA
If running new cable isn’t practical, powerline adapters can use your electrical wiring for data, and MoCA adapters can use existing coaxial cable. We explain how each works, which homes they tend to suit, and how they compare with Wi-Fi extenders.
