Why is my broadband not working well?
Broadband speed, or bandwidth, is the maximum capacity of your internet connection, but it is network stability (low packet loss) and connectivity (low latency) within your home that truly dictates your online experience. A poor internal network creates bottlenecks that prevent you from utilizing your full broadband speed.
Speed vs. Stability
Imagine your high-speed broadband connection (e.g., 500 Mbps fiber) as a wide highway leading to your property.
Broadband Speed (Bandwidth): This is the width of the highway—the maximum data that can enter your home.
Network Stability & Connectivity: This is the quality of the roads inside your property. If these internal roads are full of potholes (high packet loss) or have long detours (high latency), your devices can't drive at the highway's speed.
A network with high latency (e.g., above 50ms) makes real-time activities like video calls stutter and online gaming lag, even if the overall download speed is high. An unstable network with high packet loss requires data to be resent repeatedly, which drastically reduces the usable speed and causes connection drops.
The Powerline Adapter Bottleneck
Powerline adapters use a building's electrical wiring to transmit network data, which is convenient but highly susceptible to interference and instability.
How Powerline Adapters Reduce Performance
Electrical Interference ("Noise"): Your home's electrical wires carry signals for devices like refrigerators and microwaves. These devices create electrical noise that interferes with the powerline data signal. The adapter must constantly compensate for this noise, leading to slow speeds and frequent packet loss.
Circuit Breaks and Distance: The signal must travel through the entire electrical circuit. If the adapters are on different electrical circuits or far apart, the signal degrades severely.
Surge Protector/Extension Lead Usage: Plugging an adapter into a surge protector often filters out the network signal, causing an immediate and significant speed drop.
Powerline adapters are generally the least reliable method for extending a network and can often deliver performance worse than a weak WiFi signal.
Modern Solutions: Wired vs. Mesh WiFi
To overcome the performance issues caused by Powerline, you must establish a reliable connection between your router and your devices or extended access points.
Wired Network (Ethernet and Hardwired Access Points)
A wired network involves running Ethernet cables (like Cat6) from a central switch to fixed devices or to Access Points (APs) installed throughout the home.
Products: Professional-grade systems from Ubiquiti UniFi and Ruijie Reyee use wired APs to provide a massive, stable WiFi bubble. TP-Link Omada is another popular option in this category. These systems offer fine-grained control via a central controller.
How it Works: The cable is the "backhaul" (the main link back to the router). This is the gold standard for stability.
Best For: Max speed, zero-lag gaming, 4K/8K media streaming, and fixed workstations.
Mesh WiFi Network
A mesh system consists of a main router and several satellite nodes that communicate wirelessly with each other, forming a single, seamless network.
Products: Consumer-friendly systems like TP-Link Deco simplify setup and are excellent for broad coverage. Ubiquiti and Ruijie APs can also be set up to form a mesh network, but they are generally less plug-and-play than Deco.
How it Works: The nodes wirelessly relay the signal from the main router to your devices.
Best For: Large or multi-story homes where running Ethernet cable is impossible, providing easy, whole-home coverage for mobile devices.
Wired Network Advantages Over Mesh
A wired network (or a Mesh system that uses wired backhaul) is always superior to a purely wireless Mesh system when speed and stability are the priority.
Stability Highest. Immunity to interference ensures virtually zero packet loss. Moderate. Performance can fluctuate due to interference from walls, floors, and distance between nodes.
Speed/Throughput Full broadband speed to the connected device/AP. No speed loss. Speed Reduction. Wireless "hops" between nodes halve the speed, resulting in lower throughput at the satellite nodes.
Latency (Lag) Lowest (typically <5ms). Best for lag-sensitive applications. Higher. The wireless signal must travel through multiple nodes, adding delay (latency) with each hop.
Installation Complex (requires running cables in walls/ceilings). Simple (plug-and-play setup via an app).
Cost Can be higher due to cable and labor costs. Generally lower upfront cost for equipment.
From Problem to Perfect Connectivity: The Cornwall WiFi Services Design Process
At Cornwall WiFi Services, we understand that a high-performance network should be heard, not seen. Our process is built on two core pillars: delivering unbeatable reliability through expert design and ensuring seamless aesthetic integration into your home or business, especially across the unique and often challenging properties in Cornwall.
Phase 1: The Essential Professional WiFi Site Survey
A network survey is the critical first step that separates a reliable, high-speed network from a frustrating, off-the-shelf solution. This is particularly vital in Cornwall's traditional stone buildings, long farmhouses, or sprawling holiday parks, where thick walls and large distances create connectivity dead zones.
What Our Survey Measures (Performance Focused):
Signal Strength and Coverage Mapping: We use professional tools (like Ekahau or similar) to generate a "heat map" of your property, pinpointing existing dead zones and areas of weak coverage. This eliminates guesswork.
Interference Detection: We use a spectrum analyser to identify sources of signal "noise" such as microwaves, neighbouring networks, smart devices, and building materials (like slate and stone), which can severely degrade performance.
Capacity Planning (Client Needs): We assess the number and type of devices (4K TVs, security cameras, smart home hubs, business workstations) to ensure the network can handle peak demand without bottlenecks, guaranteeing consistent speeds for streaming, remote work, and online gaming.
Backhaul Assessment: We determine the most stable route for data—whether a new Cat6/Cat7 Ethernet run (the gold standard for stability) or a high-speed Point-to-Point (PtP) wireless link for outbuildings, farms, or holiday lodges.
Phase 2: Bespoke Network Design & Aesthetic Integration
Using the data from the survey, we design a network that is as invisible as it is fast. We specialise in enterprise-grade equipment like Ubiquiti UniFi or similar professional systems known for their minimalist design.
Design Principle The Cornwall WiFi Services - Approach Benefit to the Client
Optimal Access Point (AP) Placement APs are strategically placed to ensure maximum radio coverage with minimal units. This avoids clutter and ensures they are never placed in visually prominent areas unless absolutely necessary. Perfect, uniform WiFi coverage without an array of visible equipment.
Aesthetic Concealment We utilise low-profile, ceiling-mounted or in-wall APs (often resembling smoke detectors). Cabling is discreetly run within walls, floor voids, or trunking designed to match existing décor. A powerful network that blends seamlessly into the architecture of a historic Cornish cottage or a modern home.
Centralised Hardware All primary networking gear (router, switch, network controller) is housed in a clean, organised cabinet, typically in a utility room, loft, or basement. This keeps the core infrastructure out of sight and safe. Tidy and Organised: No unsightly routers or flashing lights visible to the client or their guests.
Tailored Solutions We recommend specific hardware (e.g., weatherproof Ubiquiti airMAX for linking a main house to a distant holiday let) to ensure reliable connectivity across the entire, often fragmented, Cornish property. Future-proof reliability that caters to the specific demands of the client (e.g., secure guest networks for B&Bs).
