Wireless keeps improving, but a physical cable is faster, lower in latency, and immune to interference. If you have open walls, a crawlable attic, or a basement with exposed joists, this is the cheapest permanent speed boost you will ever buy.\n\n## What changed in 2026\n\nThe cable in the wall has not changed much, but the case for running it has. A few things worth knowing before you start:\n\n- **2.5GbE is mainstream.** New routers, motherboards, and some laptops ship with 2.5 gigabit ports, so plain Cat5e or Cat6 is enough for nearly every home.\n- **Multi-gig internet is common.** Fiber plans past 1 gigabit are widely sold now, and only a wired backbone lets several devices use that speed at once.\n- **Wired backhaul is the norm for mesh.** Running one cable to each mesh node turns a flaky wireless system into a rock-solid one.\n- **Prewired markups keep climbing.** Integrators charge a lot for structured wiring, so a few DIY drops are far cheaper if you are comfortable on a ladder.\n\n## Plan the drops before you touch a cable\n\nWalk the house and decide where wired ports actually matter: the TV wall, a home office, gaming spots, and wherever each mesh node will live. Everything should trace back to one central spot near your modem, where a small patch panel or switch lives. This is a home-run or \"star\" layout, and it is the only design worth doing.\n\nA few honest planning notes:\n\n- **Run two cables to each location, not one.** The cable is cheap; fishing a wall is the expensive part, and a spare pays for itself the first time you need it.\n- **Leave slack** at both ends, a few feet coiled in the wall or attic, so you can re-terminate a mistake.\n- **Keep runs under about 300 feet.** Ethernet tops out near 100 meters per run; almost no home comes close, so this is rarely a real limit.\n\n## Pick the right cable and parts\n\nDo not overbuy here. Plenty of people insist on the priciest cable to \"future-proof,\" but the physics rarely justify it in a house.\n\n| Cable | Realistic speed at home | Best for | Watch out for |\n| --- | --- | --- | --- |\n| Cat5e | 1GbE, often 2.5GbE on short runs | Most existing homes | Fine; do not rip it out to \"upgrade\" |\n| Cat6 | 1GbE easily, up to 10GbE short | New runs, the safe default | Stiffer, slightly harder to pull |\n| Cat6a | 10GbE across full-length runs | Offices, long 10-gig links | Thick, pricey, overkill for most |\n| Cat7/Cat8 | Marketing more than benefit | Almost nobody | Odd connectors, little real payoff |\n\nFor nearly every house, solid-core Cat6 for in-wall runs is the sweet spot. Add keystone jacks, wall plates, a patch panel, and stranded patch cables for the final hop to each device. Buy a punch-down tool and a cheap cable tester, and check current parts prices yourself.\n\n## Run, terminate, and test\n\nThe order that saves the most grief:\n\n- **Fish the cable first,** from the central panel to each room, using the attic or basement so you drill through fewer walls.\n- **Terminate to keystone jacks,** not crimped RJ45 plugs, for anything in a wall; jacks are far more forgiving.\n- **Follow one standard end to end.** Use T568B on every jack; mixing standards causes the classic \"it links but crawls\" problem.\n- **Test every run** with a cheap tester before you close up walls. Finding a bad punch-down now beats opening drywall later.\n\nHonest caveat: fishing cable through finished walls is the hard part, and it can turn a weekend job into a multi-day fight with insulation and fire blocks. If a run means cutting into several walls, price out a local pro for that one drop.\n\n## What to skip\n\n- **Skip Cat7 and Cat8** for a normal home; you pay for connectors and stiffness you will never use.\n- **Skip crimping your own RJ45 plugs** in walls; keystone jacks are more reliable and easier to redo.\n- **Skip running only one cable** per location; the second cable is almost free compared with redoing the pull.\n- **Skip ripping out working Cat5e.** If it passes a test, it likely handles your plan fine.\n\n## FAQ\n\n**Do I need Cat6a or is Cat6 enough?**\nFor almost every home, Cat6 is enough and Cat6a is overkill. Choose Cat6a only if you have specific 10-gigabit gear over long, full-length runs.\n\n**Can I wire ethernet without opening every wall?**\nOften yes. Attics, basements, and closets let you drop cable into rooms with minimal drilling, which is why single-story homes with an accessible attic are easiest to wire.\n\n**Is wired really worth it if my WiFi is fast?**\nFor anything that stays put, yes. Wired gives lower latency and steadier speeds, and it frees WiFi airtime for your phones and tablets too.\n\n**Should I hire a pro or do it myself?**\nSimple runs through open spaces are very DIY-friendly. Consider a pro for tricky fished walls, long conduit runs, or a cleanly labeled patch panel.\n\n## Where to go next\n\nOnce the cable is in the wall, feed it with the right gear: our [how to choose a router 2026](/blog/how-to-choose-a-router-2026) guide helps you avoid paying for speed your plan cannot use, and [best mesh WiFi systems 2026](/blog/best-mesh-wifi-systems-2026) covers kits that support wired backhaul.
