To make the best use of the internet at home, it is not enough just to choose good equipment, but you must take into consideration some essential precautions to get the best wifi signal quality.
The blog has already provided tips on choosing the ideal router, and today will talk about some techniques that can be employed to make the most of wireless internet.
Where to position the router?
The router should be positioned in an obstacle-free location, preferably in the room where the network will be accessed most of the time. The more hidden the device is, the smaller the signal range and the stability of the connection.
Therefore, avoid installing the router inside counters, behind decoration utensils, under shelves, etc. And it's good that it stays away from the base of the cordless phone.
The height at which it is positioned also contributes to better signal propagation: higher is better, but what prevails is the absence of obstacles.
The wireless protocol available on most modern routers can reach about 400 meters in the open. In practice, this range is significantly shorter because of obstacles and interference.
In places with different environments separated by walls, the ideal is to use a signal repeater. This device should be installed in the position where the original signal arrives at the best intensity. How to know which one? On any device that connects to the wireless network, check the icon that indicates the signal strength.
Read below about indicated applications for measuring signal strength.
How to measure signal strength and internet speed?
You can easily evaluate signal quality and internet speed using mobile applications. Among the free apps tested, the most intuitive for those without technical skills is called "Wi-Fi Monitor: WiFi Network Analyzer", available only for Android devices.
It displays available networks, how often they are operating, how many users are connected to the network, signal quality, and download and upload speeds.
The strength of the app is its simplicity, it requires advanced knowledge to interpret the results presented in the diagnosis.
For iOS phones, there is an app with equivalent functionality called "Speed Test & WiFi Analyzer".
Once you have installed the app you chose for your device, simply run it to get signal strength evaluation. The displayed result must be greater than 70% to be considered optimal. The signal is also represented by the measurement "dBm" (decibel milliwatt, unit of measurement used primarily for telecommunications to express absolute power).

What is the difference between the 2.4 GHz and 5 GHz signal on wifi routers?
The 2.4 GHz frequency is older, used in cordless phones, garage remote control and internet router.
As it is the most common in the market, it is necessary to evaluate the number of devices simultaneously connected in the same area and operating at this frequency, as there may be interference and compromise the signal quality.
Ideally, 2.4 GHz wifi will support transfer rates between 450 Mbps or 600 Mbps, depending on the router class.
To better understand what these speed rates represent in practice, we can see the settings needed to watch an HD movie via streaming. In this definition, a 5 Mbps broadband connection is required; Ultra HD must have a broadband connection speed of at least 25 Mbps.
To evaluate network performance, you must also consider the number of devices simultaneously connected to the router and the type of activity that will be performed.
Routers operating at 5GHz will support downloads of up to 1,300 Mbps. But equipment with this configuration is usually installed in a corporate environment, which has a higher demand for data.
There is no better frequency than the other, but in one of them there may be a better setting for your environment.
In this case, it is necessary to evaluate the signal quality, the size of the environment, the amount of equipment operating in the same band and the need for transmission range.
A simple router is capable of transmitting the signal from a 15 Mbps broadband network to 5 devices simultaneously, enabling social network browsing, messaging applications, listening to music online.
For games, streaming, downloads on the same number of simultaneously connected devices, a minimum of 25 Mbps is recommended.
In addition to the tips presented above, the reader must consider the need to keep the operating system of the handsets, whether a computer or smartphone, always up to date.
On computers, this tip also applies to the wireless network card, which should be up-to-date with the driver for better browsing performance.
