Guide topics
The guide is divided into four topics. The first explains what a home network is made of and where its weak points are. The second covers what to do when the connection drops or slows down. The third is about calls and video, and the fourth about protecting the network and agreeing on rules for the whole family.
A home network is not one box but a chain: the cable, the router, the air between the walls and the device itself. A fault almost always sits in one link, and it can be found.
The topics cover questions that come up in any home: where to put the router, why everything slows down in the evening, how to talk on video without stuttering, how to keep strangers off the network. We explain general principles and do not compare companies, device models or plans.
The home network
Your provider brings a cable into your home, the router turns it into a wireless network, and devices connect to the router by cable or over the air. Wi-Fi uses the 2.4 GHz and 5 GHz bands, and newer devices also support 6 GHz. The first passes through walls better; the second is usually faster close to the router.
- Five things about your network

When it doesn’t work
The connection can disappear completely, become slow, or work in one room and not in another. Each case has its own order of checks, and it almost always starts with a simple question: is the problem with one device or with all of them?
- Internet down: what to check
A step-by-step article with hypothetical examples, common mistakes and a checklist.

Why speed is lower than promised and how to measure it honestly.
- Collection for remote work
What to prepare in advance so an outage does not ruin your working day.
Calls and video
A video call needs a steady connection without drop-outs more than it needs high speed. Mobile signal indoors depends on how thick the walls are, which floor you are on and where the windows face. In Russia and across the EU, 112 is the single emergency number, and in Russia it can usually be dialled even without a SIM card or credit; readers elsewhere should use their local emergency number.

Safety and family
Three things protect a network: encryption, strong passwords and up-to-date router firmware. WPA3 is the current Wi-Fi security standard, introduced by the Wi-Fi Alliance in 2018; WPA2 is still found everywhere. In a family, agreements come on top of that: when and how children use their devices.
