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.

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.

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.

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. Daranet Home Lab & Efficiency Mon, 09 Nov 2026 09:34:24 GMT https://daranet.co.uk/supplied-router-on-trial-isp-cpe-measurement-plan/ https://daranet.co.uk/supplied-router-on-trial-isp-cpe-measurement-plan/ 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.

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.

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.

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.

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.

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. Daranet Home Lab & Efficiency Sun, 08 Nov 2026 13:41:39 GMT https://daranet.co.uk/before-the-dial-tone-dies-analogue-audit-2027/ https://daranet.co.uk/before-the-dial-tone-dies-analogue-audit-2027/ 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. Daranet Broadband & Connectivity Sun, 08 Nov 2026 09:41:38 GMT https://daranet.co.uk/names-you-own-local-resolver-split-horizon-dns/ https://daranet.co.uk/names-you-own-local-resolver-split-horizon-dns/ 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.

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.

This explainer covers bridge-mode ISP equipment, managed switches, firewall policy and the mDNS reflection that keeps household devices usable.

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.

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. Daranet Home Lab & Efficiency Sun, 08 Nov 2026 01:45:33 GMT https://daranet.co.uk/uk-full-fibre-cgnat-double-nat-ipv6-drift/ https://daranet.co.uk/uk-full-fibre-cgnat-double-nat-ipv6-drift/ 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.
