The Lights on the Wall: Reading an Openreach ONT Without Guessing

The Openreach optical network terminal is the quiet boundary between your network and the fibre outside. Its LEDs are limited, but read in the right order they can separate a dead optical link from a router problem before you pick up the phone.

The Figure on the Box Is Not a Promise: Measuring Real UPS Runtime Before the Winter Cuts

Manufacturer runtime charts assume a tidy resistive load that few home labs resemble. This guide sets out a repeatable, low-risk method for measuring actual UPS runtime against the load you really draw, then converting the result into a shutdown plan for the 2026 storm season.

Somebody Else's Hands: Proving Your Network Documentation Actually Works

Most small-network documentation is written for the person who already knows the answers. This guide sets out a handover dossier built for a competent stranger, and a drill that tests it under a simulated outage before a real one arrives at an inconvenient hour.

The Power Behind the Port: Sizing PoE for a Small UK Network

A switch's PoE figure is a ceiling, not a promise. This walkthrough shows UK admins and home-lab builders how to turn port classes, cable losses and UPS headroom into a workable power plan for cameras and access points.

The Supplied Router on Trial: A Measurement Plan for ISP CPE

ISP-supplied routers are routinely declared the weak link before any evidence has been collected. This is a repeatable test plan for establishing whether the box in question is genuinely limiting a UK home lab, and for deciding when a replacement can be justified on measured grounds rather than assumption.

Copper Already in the Wall: A Measured Path to 2.5GbE in a UK Home Lab

2.5GbE is the pragmatic middle ground for UK home labs, but the upgrade is rarely about the cable alone. This guide sets out how to test existing Cat5e runs, identify the true bottlenecks in routers, access points and NAS storage, and choose switches that will not turn a spare room into a wind tunnel.

Two Lines, One Cutover: Planning a Fibre Migration That Nobody Notices

Ofcom's One Touch Switch has removed the administrative friction from changing ISP, but none of the technical risk. This is a cutover runbook for home labs and small offices: staged router configurations, TTL planning, port-forward inventories and a rollback path that works whether or not you get an overlap window.

Out of the House, Onto the LAN: Getting a Garden Office Properly Connected

A detached garden office is thirty metres of lawn away from the network and often several volts away from its earth. This decision guide compares armoured copper in ducting, preterminated fibre and point-to-point wireless, and sets out the earthing, surge and weatherproofing details that separate a permanent link from a seasonal bodge.

Exit Strategy: Keeping a Small Network Alive When a UK Altnet Folds

Consolidation among UK altnets is no longer a thought experiment. This contingency plan helps home labs and small offices document contracts, preserve DNS and remote access, and switch providers without taking self-hosted services offline.

The Sixth-GHz Decision: Separating Wi-Fi 7 Signal from Noise in a UK Lab

Wi-Fi 7 is easy to sell and harder to justify. This measured guide examines what the UK's 6 GHz rules actually permit, which lab workloads benefit, and how to test before replacing working access points.

Before the Dial Tone Dies: An Analogue Audit for the January 2027 Switch-Off

Openreach's PSTN withdrawal reaches its hard stop at the end of January 2027, and the lines most likely to be missed are the ones nobody uses daily. This checklist covers how to inventory analogue dependencies, test them with evidence, and keep a working fallback for the morning the copper goes quiet.

Names You Own: Running a Local Resolver Without Losing the Internet When It Fails

DNS is the cheapest performance, privacy and control lever in a small network, yet most UK setups hand it entirely to the ISP. A local resolver with split-horizon zones and encrypted upstreams is straightforward to build; making it fail safely is the part that separates a lab from a liability.

When the Fibre Fails: A Practical 5G Fallback for the UK Home Office

Openreach faults rarely announce themselves before a deadline. This guide sets out a credible 5G failover design for a UK home office, from SIM selection and antenna placement to health checks and a sensible bill of materials.

Segmentation Without a Rack: VLANs for a Victorian Terrace Home Network

A Victorian terrace rarely has room for a comms cabinet, but it can still support a segmented network. This explainer covers bridge-mode ISP equipment, managed switches, firewall policy and the mDNS reflection that keeps household devices usable.

Upstream Is the New Downstream: Redesigning a UK Home Lab Around Symmetric FTTP

Symmetric and near-symmetric FTTP has quietly removed the upload ceiling that shaped a generation of home lab design. This is a practical audit of the workloads, backup windows, VPN topologies and QoS rules that are still tuned for 20 Mb/s - and how to re-plan them around real upstream capacity.

No drills, no permanent cabling, no argument with the letting agent at the end of the tenancy. A practical build guide for UK renters who still want a properly segmented lab - covering adhesive trunking, flat Cat6, free-standing racks, patch panel alternatives and a teardown that takes one afternoon.

The Address Is the Problem: Diagnosing CGNAT, Double NAT and IPv6 Drift on UK Full-Fibre

A full-fibre connection can still leave you without a public IPv4 address, behind two routers, or with IPv6 that works only on some devices. This Daranet guide sets out the checks, workarounds and ISP questions that separate the three problems.

Watts Behind the Wall: A £50 Energy Audit for a UK Home Lab

Always-on switches, NAS boxes and PoE gear can cost more than the hardware they support. Here is a practical £50 audit using a UK smart meter and a plug-in monitor, with the arithmetic to decide what stays powered.
