Practically every household, as well as most companies, has recently used wireless Wi-Fi through routers to connect computers, laptops, tablets and other devices.
Sometimes there are troubles with connection speed on the network, some of them are coming from your provider of the Internet, but many of them you can find out and remove yourself. Before you start despairing and complaining, review the options that can have a major impact on your connection speed.
The connection between the router and the connected devices is one of the most common things that can negatively affect the level of the transmitted signal. These problems manifest themselves in both directions, ie during the downloading of data (download) and sending them (upload). These are usually insufficient coverage of the space by the wireless signal, the obstacles in the direction of transmission or interferences of the transmitted signal. The combination of several mentioned factors at the same time is no exception. The frequencies 2.4 GHz, sometimes 5 GHz, are most commonly used for regular wireless connections.
If you receive the signal without problems and at the appropriate speed near the router, and with more remote devices the quality and strength and speed of the received signal is significantly worse, there are several different options as the solutions:
Warning: before starting the measurement, we measure the speed of the incoming signal and then the speed of the connection just behind the router. This is how to eliminate the problem of speed reduction caused directly by the router. (We'll get to this potential problem a little further). Measurements must always be made in such a way that at that time (measurement is very fast) there is no data transfer in either direction. You can use one of the popular tools available for free on the Internet, such as https://rychlost.cz/. You should be mainly interested in data on the speed of downloading data, but also sending data (upload), for online players, the response (ping) is undoubtedly very important, too. You do not have to copy the measured values laboriously, because if you perform repeated measurements using the same program, the results of all measurements will remain in memory and you will get a reliable averaged overview in the form of a graph or table. Repeat the measurement at different times of the day and on weekends and weekdays, because the speed may vary significantly.
The router can also be a source of problems, you can find out if you lose it by above mentioned measuring the connection speed. The first step should be to thoroughly check the router settings. You can also try a simple but often effective solution - restart the router, the problem is often solved really immediately. With older routers, sometimes the device no longer meets the requirements and does not provide adequate performance. In such a case, there is only one reasonable solution, which is to purchase a new router. If multiple users are connected to the router, you also need to check the data throughput and available supported technologies.
Classic connection testers measure the speed between a terminal and a point on the Internet (a specific server). Sometimes, however, it is good to measure the speed between the terminal and the router on the local network. It can be good for that an android application available on Google Play called " Wifi Speed Test ". This application measures speed over UDP packets, which may not check the delivery status. For this reason, it may show significantly more under certain conditions that cannot be verified. But mostly the app shows exactly.

Just hold your phone up to a terminal and within moments the payment is made. However, NFC technology is capable of much more. We will explain what NFC is and how it works, what actually happens during NFC mobile payments, what else you can use it for, and how secure it is. We will also show what NFC tags are and how they can simplify some daily tasks.

What if there was a full-day internet outage? An immediate collapse of society wouldn't occur, but daily operations would quickly become complicated because today's world is more dependent on the internet than we often realize. Which services would stop functioning first, and what would happen with payments, transportation, or work?

WPA, WPA2, WPA3, AES or TKIP? Wi-Fi security settings might initially seem unnecessarily complicated. However, when you understand what each abbreviation stands for, it becomes fairly simple. Therefore, we'll explain the differences between them and which is the best choice today. We'll also suggest what settings to choose if you have older devices at home that don't support the latest standard.

Do you think incognito mode hides you from everyone on the internet? In reality, it works a bit differently. We explain what it actually does, when it's sensible to use it, who can still see your activity, and whether history can be traced in incognito mode.

AI can answer almost any question in just a few seconds. However, sometimes it confidently states information that is not true. Why does this happen and what are so-called AI hallucinations? In this article, we'll explain how large language models work, why they sometimes create false answers and how developers are gradually trying to mitigate this issue.

Behind every loaded video, photo, or webpage is a technology called CDN. It is used by streaming services, social networks, and regular websites, yet many people have never heard of it. In this article, we will explain what this abbreviation means, how it works, why internet content is stored in various locations around the world, and why today's internet can hardly do without it.
