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.
The Internet of Things is one of the current phenomena in the field of IT and the Internet. Read how to use the Internet of Things (IoT) in your home and what to look out when you are using it.
If you want to connect your computer to the Internet or your home network with a cable, you have two options. You can either buy an already finished cable with connectors in the required length in the store, or you can make it yourself. The home production of the network cable is necessary especially if you need to pass it through a narrow hole into which the connector doesn't fit. You usually have to install it after passing the cable through a small hole. Read how to make such a cable and how to repair that current one.
A purchase of a router is waiting for you, but when you look at the offer, you only see boxes that differ in price and appearance? In that case, a basic overview of important parameters can not only save you a lot of money, but also significantly speed up the Internet.
The use of switches (network switches) is currently the prerogative of company networks in particular, but they are also used in home networks. In the market you will find switches in various price categories, which differ in parameters and additional functions. What to focus on and how to choose a new switch? This is the issue to what we will apply in the following lines.
When you have a fast connection, but there are significant speed fluctuations, something is probably wrong. It is a question, where to start looking. Basically, you should first verify if the connection really offers the speed which you have agreed with the provider in the contract. The problems can also be caused by a large number of running applications, it is necessary to check it and possibly leave only those one that you are currently using. Then check the aggregation and after that the router.
