If you belong to the Internet users for whom the dream goal is a fast and reliable connection via a router, you may are thinking about the choice between the frequency of 2,4 GHz and 5 GHz. Which of them will be more suitable for you and will meet better all the requirements?
The answer to the question from the introduction is not as simple as it might seem at first sight. Each frequency has actually its pluses, but none of them can avoid some of the details that might not be convenient for you in practice. So before choosing the device, you should go through the options carefully and get acquainted with the qualities of the available routers.
Today's modern Wi-Fi routers work on two different frequencies. Regarding the speed, the transmission in the 5 GHz band is definitely better. When the tests are performed under optimal conditions, it is really rapidly faster in the area of download and upload. However, there are already mentioned optimal conditions, which are definitely not possible to achieve every time. The short-distance connection without an obstacle is at the 5 GHz frequency problem-free and the the band is usually more free than at 2.4 GHz frequency. This may cause an unwanted interference. On the other hand, the lower frequency (also 2.4 GHz) get through the potential obstacles much more better, although it is significantly slower.
Many models of the modern routers can easily without problems transmit a signal on both mentioned frequencies at the same time, so either we choose the desired frequency on the receiving device manually, or the one that currently offers a better connection will be automatically set itself. Therefore, if you decide to set up your own domestic wireless network using a WiFi router, think about locating it so that the reception is as easy as possible and the signal is not significantly disturbed or obstructed. You can use both frequencies at the same moment and connect to a concrete network those devices for which it pays more.
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.
