Everything we publish goes into one place rather than two. Rather than running a separate blog that slowly fills with announcements, our writing lives in the Connectivity Academy — the same articles, kept up to date, organised by subject instead of by the date somebody happened to write them.
This blog is the Academy
There is no separate blog archive and no CMS behind this page. Every post below is an Academy article, filtered and sorted here by when it was last updated. Articles are revised in place as equipment and conditions change, so an old post does not quietly become wrong. The most recent revision was 4 Aug 2026.
Most recently updated
Sorted by revision date, so what you read first is what we have most recently checked.
When a SIM works in a phone but not in a router, the APN is almost always why. What an access point name does, where to find it, and how to enter it correctly.
Updated
Network equipment draws far less power than people assume, so staying online through an outage is cheap and straightforward — if you size the backup against the real load.
Updated
A specification-by-specification guide to picking a router that suits your building, your devices and your signal, rather than the one with the largest number on the box.

Slowness has perhaps six common causes and they need completely different fixes. A systematic way to find yours in about twenty minutes instead of guessing for a fortnight.
Updated
Practical, proportionate security for a home or small business network. The handful of settings that genuinely matter, and the popular advice that is worth ignoring.
Updated
Mesh solves coverage, not speed, and only when the nodes are placed correctly. How to plan, position and verify a mesh system in a block-built Ghanaian home or office.
Updated
The practical steps of a real antenna installation — choosing the type, finding the mast, mounting safely, aiming by measurement, and weatherproofing so the job lasts.
Updated
From unboxing to a properly secured, well-placed network in under half an hour, including the settings most people leave at the defaults and later regret.
Updated
A methodical route from free fixes to paid ones, in the order that actually pays off. Read the numbers, move the router, then spend money only where the numbers say it will help.
Updated
Low-earth-orbit satellite internet reaches places no mast serves. Here is how the technology works, what a site genuinely needs to support it, and where it is the right answer rather than an expensive one.
Updated
Wi-Fi and mobile data are two different links in the same chain, and confusing them is behind a surprising number of support calls. Here is how to tell which one is actually letting you down.
Updated
Both turn a SIM into Wi-Fi, but they are engineered for opposite jobs. A clear comparison of power, antennas, device counts and cost so you buy the right one the first time.
Updated
5G is genuinely a step change in capacity and latency, but only where it is actually deployed and only if your signal is strong. This guide separates the engineering from the marketing so you can decide honestly.
Updated
4G LTE remains the backbone of internet access across most of Ghana. Here is what the technology actually does, what really governs the speed you get, and why the band list on the box matters far more than the marketing badge.

The Device Finder turns the general advice in these posts into a specific shortlist, and a survey confirms it on site before you buy anything.
