Almost every technical problem at home ends up at the network sooner or later. This category explains how home internet is put together and how to narrow down faults yourself: positioning and configuring the router, Wi-Fi channels and frequency bands, improving coverage with repeaters or a mesh network, network cables and powerline as alternatives, a guest network for visitors, and sensible settings for parental controls and device management. We also show how to tell whether the problem is the line, the router or the device, and when calling the provider is the faster route. Explained clearly, without jargon, with step-by-step instructions. We also cover typical sources of interference at home and which details a provider needs on the phone so troubleshooting goes faster.
