Cat6 still beats WiFi for work, gaming, CCTV and access point backhaul. When a wired run is worth it in Berkshire homes, and when it is not.

If you work from home, stream in 4K, game online, or rely on video calls, you have probably experienced the frustrations of dropped connections and inconsistent speeds. Running Ethernet cable through your house solves these problems permanently, but is the investment worth it? Here is what you need to know. ## What Ethernet Cable Actually Does Ethernet is a wired connection that links devices directly to your network using a physical cable. Unlike WiFi, which broadcasts a signal through the air, Ethernet delivers data through a copper cable with no interference, no signal loss, and no contention from other devices. The result is a faster, more stable, and lower latency connection. Modern installations use Cat6 or Cat6a cable, which supports speeds up to 10 Gbps over short distances. For most homes, this is far beyond what current broadband speeds require, which means the cabling will remain future proof for years. A single Cat6 cable terminates at a wall plate or patch panel, giving you a clean, permanent Ethernet point wherever you need it. ## When Ethernet Is Worth the Investment Not every device in your home needs a wired connection, but certain use cases benefit enormously from one. If any of the following apply to you, Ethernet cabling is almost certainly worth it. ### Working From Home Video calls on Teams, Zoom, or Google Meet are one of the most demanding tasks for a home network. They require consistent upload and download speeds with low latency. WiFi can handle this when conditions are good, but it only takes one family member streaming a film or a microwave running to cause your call to freeze. A wired connection to your home office removes that risk entirely. ### Gaming Online gaming is extremely sensitive to latency and packet loss. Even small WiFi fluctuations can cause lag spikes that affect gameplay. Connecting your console or PC via Ethernet gives you the lowest possible ping and the most stable connection. For competitive gaming, this is not optional. ### Streaming and Smart Home Devices Smart TVs, Apple TVs, and streaming devices all perform better on wired connections. 4K and HDR streaming require sustained bandwidth, and WiFi buffering can interrupt the experience. Wiring your main entertainment areas ensures smooth, uninterrupted playback every time. ### WiFi Access Points This is one of the most impactful uses for Ethernet cabling. Instead of relying on wireless mesh repeaters, you can connect [wired access points](https://berkshirewifi.co.uk/blog/why-wired-access-points-matter/) throughout your home. Each access point connects back to your router via Ethernet, delivering full speed WiFi to every room without the performance loss that wireless repeaters introduce. This is the foundation of a proper [whole home WiFi installation](https://berkshirewifi.co.uk/whole-home-wifi-installation/). ## What Does Ethernet Installation Involve? Professional Ethernet installation involves routing Cat6 cable from a central point, usually near your router or a network cabinet, to each room where a connection is needed. Cables are typically run through lofts, under floors, or within wall cavities to keep them hidden. Each cable terminates at a flush mounted wall plate, giving you a clean, permanent connection point. The number of cables and the complexity of the routing depends on your property. A typical three bedroom house might need four to six cable runs, while a larger property could require ten or more. We carry out a site survey before every installation to plan the most efficient routes and identify any access challenges. Our [data cabling service](https://berkshirewifi.co.uk/data-cabling/) covers everything from single cable runs to full house wiring projects. Every installation is tested and certified to ensure it meets performance standards. ## Can You Run Ethernet Cable Yourself? It is technically possible to run Ethernet cable yourself, but there are good reasons to have it done professionally. Routing cables through walls and lofts requires knowledge of building construction, and poorly terminated cables will cause intermittent connection problems that are difficult to diagnose. Professional installation also means each cable is tested with specialist equipment to verify the connection meets Cat6 standards. This matters because a cable that appears to work but has a poor termination can still cause packet loss, reduced speeds, or complete dropouts under load. The cosmetic finish also makes a difference. A professional installer will use trunking, wall plates, and patch panels to keep everything tidy. Running cables externally, across skirting boards, or through door frames is not only unsightly but can create trip hazards and damage risks. ## Ethernet vs Powerline Adapters Powerline adapters are sometimes suggested as an alternative to running cable. These devices use your home’s electrical wiring to carry network data. While they can work in some situations, they are unreliable in many UK homes. Older wiring, separate ring mains, and electrical interference from appliances all reduce powerline performance significantly. In our experience, powerline adapters rarely deliver more than a fraction of their advertised speeds. They are also prone to dropouts and latency spikes. For anything beyond casual browsing, a direct Ethernet connection is far more reliable. ## Ethernet vs WiFi 6 and WiFi 7 Newer WiFi standards like WiFi 6 and WiFi 7 offer impressive headline speeds, but they still share bandwidth between devices and suffer from signal degradation through walls. Ethernet does not have these limitations. A wired connection delivers dedicated bandwidth to each device with zero interference. The ideal setup combines both: Ethernet cabling as the backbone of your home network, with WiFi access points connected via cable to provide wireless coverage everywhere else. This is the approach we recommend and install for homeowners who want the best of both worlds.

The cost of Ethernet installation depends on the number of cable runs, the length of each run, and the complexity of the routing. A single cable run in a straightforward property is relatively affordable, while a full house installation with multiple points across several floors will cost more. The key thing to consider is value over time. Unlike WiFi equipment that needs replacing every few years, Cat6 cabling is a permanent upgrade to your property. It adds genuine value, particularly for buyers who work from home or have high connectivity needs. We provide clear, itemised quotes after a site survey so you know exactly what is involved before any work begins. ## Is It Worth It? Our Verdict If you work from home, game, stream, or plan to install a proper [mesh WiFi system](https://berkshirewifi.co.uk/mesh-wifi-installation/) with wired backhaul, then yes, running Ethernet cable is absolutely worth it. It is a one time investment that solves connectivity problems permanently and future proofs your home network for years to come.

Yes, for the jobs WiFi is bad at: video calls, gaming, CCTV, and feeding access points. WiFi 6 and WiFi 7 still share airtime and still die through brick. Ethernet does not. [Data cabling](https://berkshirewifi.co.uk/data-cabling/). ### What cable should I run in a house, Cat5e or Cat6? Cat6 is the default for new home runs. Cat5e still works for many devices, but Cat6 is cheap insurance and is what we pull for WiFi backhaul and PoE cameras. We cover the grades in [Cat5e vs Cat6 vs Cat6a](https://berkshirewifi.co.uk/blog/cat5e-vs-cat6-vs-cat6a-home/). ### Can you run Ethernet without ripping up the house? Usually. Lofts, voids, external trunking and existing ducts cover most Berkshire homes. Full rewire-style chasing is the exception. See [adding Ethernet without ripping up the house](https://berkshirewifi.co.uk/blog/adding-ethernet-without-ripping-up-the-house/). ### How many Ethernet points does a home need? Enough for the office, the TV wall, the access points and any CCTV recorder. Extra points in spare rooms are cheap while the loft is open.
