Как использовать программу wi-fi analyzer

Why You Need a Wifi Analyzer

The main reason why you need a wifi analyzer is to maintain your connection quality. Wifi signals are in a constant state of fluctuation. Your wifi connection can be performing well until something in the network changes and starts to impede its performance.

Troubleshooting a problem requires data collection and analysis. Without the source information on the normal operations of your network and the current behavior of the troubled system, your solution will be mere guesswork.

When your wifi starts to slow down or disconnect, a wifi analyzer will help you to identify the problem. By diagnosing the problem and addressing it, you ensure your connection stays up and running with minimal interference. A wifi analyzer enables you to run diagnostics on what is happening with your connection and provides you with the information needed to optimize your network.

For example, if your signal distribution around the house is poor, you’ll be able to use an analyzer to find this information out. That being said, wifi analyzers can be used for much more than troubleshooting your signal distribution. You can use a wifi analyzer to locate and use a less congested channel.

Sharing the same channel with nearby devices results in low connection speeds, interference, and disconnection. It’s not uncommon for channels to be shared amongst your neighbors (particularly if you live in an apartment). This is one of the most common reasons for poor connectivity and can be rectified via the use of a quality wifi analyzer.

Using a wifi analyzer can help improve your user experience, speed up browsing, and eliminate the hassle of trying to guess what factors are impeding your connection quality while troubleshooting. After all, it’s almost impossible to optimize your network if you lack the tools to be able to see what’s going on.

Many advanced wifi analyzers will have an inbuilt heatmap function. As mentioned above a wifi heatmap will produce a visual display of the signal strength in your house. You’ll be able to see where your signal is strongest and choose the best location for your router.

One of the best heatmap tools on the market is the SolarWinds Wi-Fi Heat Map.

Solar Winds allows the user to create custom wireless router heat maps and displays ‘dead zones’ where connectivity is poor. The tool works by reading the signal strength of nearby access points and indicating the quality of your connection based on signal location.

What makes this tool so effective is that the wifi heat map can produce a physical image of an entire network site. This allows you to easily identify where your site is causing problems for your connection, and what needs to be done to address it. In short, a heat map makes it easier to improve your coverage and signal strength.

What’s a WiFi Analyzer?

When it comes to wifi, signal fluctuation is incredibly common. The reason is that your wifi signal strength is constantly changing due to external conditions. Some days you’ll be able to browse without disconnecting, and others you’ll be in a battle just to stay online. This is made even more difficult if you don’t have the tools to diagnose the problem. This is where a wifi analyzer app can be useful. In a nutshell, a wifi analyzer app breaks down information from access points on your network and places it into a single screen.

For example, with a wifi analyzer app like Microsoft Wifi Analyzer, you can look at other channels on your network and identify if they are faster than your current channel. Some providers will even allow you to draw up heat maps of signal distribution in your house or office to help you find the best location for your router.

Что нужно для того, чтобы выбрать наилучший канал?

Чтобы начать производить какие-либо настройки, требуется выполнить переход во вкладку «Анализировать» и найти показатели, характеризующие качественные характеристики канала.

Расшифровка этих показателей такая:

1 — Показатели вай-фай различных пользователей, живущих в квартирах, находящихся в непосредственной близости;
2 — Силы, характеризующие работу устройств, находящихся в этих квартирах;
3 — Расчет самих каналов.

По такой таблице сложно судить о том, где находятся эти точки и какой сигнал является наиболее предпочтительным. Чтобы было легче, нужно включить отображение параметра «SSID». Это упростит поиск сети, так как будут выведены все их названия.

Важно! Удобство включения отображения параметра «Название подключения» заключается еще и в том, что на экран будет выведен список каналов с рейтингом, которые будут самыми лучшими для использования на устройстве пользователя

Анализатор для Android

Как уже говорилось, подобный софт доступен и на смартфон под управлением Андроид ОС (на iPhone нет). Сам анализатор не должен доставить никаких проблем ни при загрузке apk файла онлайн с официального источника в «Гугл Плей», ни при установке. После инсталляции его нужно просто открыть и начать проверку. По ее истечению произойдет вывод результатов с данными о том, насколько активно данная сеть применяется в данном местоположении, насколько часто включается роутер. Все это доступно во вкладке свойств и каналов.

Если графики практически не пересекаются, то значит, что домашней сети практически не мешает ни одно соседское подключение. Помимо этой информации, можно узнать и то, насколько силен такой сигнал

Важно! Сканер Wi-Fi Analyzer — одна из самых полезных программ подобного плана для телефонов. Основное преимущество заключается в очень маленьком объеме занимаемой софтом памяти на SD-карте, так как память используется только при работе в режиме online

Также в интерфейсе есть возможность выбрать русский язык.

Common WiFi Performance Issues

Even though the performance of the average WiFi network has improved significantly during the last decade, there are still many WiFi performance issues that plague users every single day:

Slow connection: There are many factors that can cause WiFi to be slow, including limited bandwidth, poor coverage, insufficient speed provided by the ISP, or signal interference caused by nearby appliances and Bluetooth devices. To fix issues with a slow WiFi connection, you should first determine whether you’re receiving a sufficiently strong signal from your router. You can easily do that with the help of a wireless network analyzer app. The best WiFi analyzer apps can even create a signal heatmap, clearly visualizing where the signal is sufficiently strong, and where it leaves something to be desired.
No internet connection: Whenever your WiFi connection stops working, you should first check if your WiFi router is operating as it should. If you see an LED indicator light flashing, telling you that the router itself can’t connect to the internet, then your ISP might be to blame. But if the router is working fine and your ISP isn’t experiencing an outage, then you need to fix the problem yourself. First, restart the router and wait a few minutes to see if this solves the problem. If it doesn’t, establish a wired connection and see if you can connect to the internet that way. If you can, log in to the admin interface and check your WiFi settings.
Unreliable performance: Does your WiFi connection often go from flawless to aggravating? Then you should know that you’re not the only one who’s experiencing issues with unreliable WiFi performance. Such issues are common because they are caused by a number of different factors, including co-channel interference, network overload, and spotty coverage. Many of these issues can be fixed by purchasing a new router, one that supports 2.4 and 5 GHz bands and technologies like MU-MIMO and beamforming. Other issues that can cause unreliable performance require careful troubleshooting using a wireless network analyzer.
Signal weak spots: Ideally, you want to see full WiFi signal strength bars on your laptop and mobile devices regardless of if you’re standing right next to your router or in the room that’s farthest away from it. Modern mesh WiFi systems make this possible, but you need to know how to use a WiFi analyzer to determine the optimum location of each node.
WiFi speeds lagging behind wired internet: If you can achieve the maximum download and upload speeds advertised by your internet service provider when connected to your router using an Ethernet cable but struggle to achieve the same speeds when connected over WiFi, you most likely need to either improve your WiFi coverage or purchase a more capable router that supports the latest wireless networking standards, such as Wi-Fi 6.
Insufficient bandwidth for multiple users: Not all WiFi networks can support multiple simultaneous users streaming online content, playing video games, or downloading large files from the web at the same time. For starters, you need a sufficiently capable router with enough processing power to serve multiple clients at the same time. The router should support Quality of Service to ensure that one person downloading a movie won’t make it impossible for everyone else to browse the web and send email messages. Technologies like MU-MIMO and beamforming can further enhance everyone’s experience.

What Does High-Performing WiFi Look Like?

Many people who learn how to use a WiFi analyzer are interested in setting up a high-performing WiFi network, but how does such a network look like? Here are a few important characteristics of a high-performing WiFi network:

Flawless coverage: A high-performing network should cover the intended area without leaving any signal weak spots where common online activities, such as streaming movies, browsing the web, or video chatting, are impossible to perform. A wireless analyzer can be used to create a coverage heatmap that clearly highlights all areas of signal weakness, making it easy to adjust the placement of the router, the position of its antennas, or the arrangement of interference-emitting appliances.
Sufficient capacity: Sometimes referred to as bandwidth, capacity determines how many people can use the WiFi network at the same time without experiencing a significant degradation in performance. Modern routers that support the latest WiFi standards have far greater capacity than old 802.11g routers, whose capacity is limited to about 22 Mbit/s. In high-usage scenarios, it’s often necessary to deploy multiple access points to provide sufficient capacity, which is where mesh networks come in, making it possible to cover a very large area with a single WiFi network broadcasted by a large number of access points.
Great speeds: Ideally, you want your WiFi network to deliver the same download and upload speeds as a wired Ethernet connection. If you’re paying for a 100 Mbit/s internet connection, you should be able to reach the maximum speed from any part of your apartment, house, or office. Modern routers use technologies such as MU-MIMO (multi-user multiple-input multiple-output) and beamforming to enhance signal strength and ensure a speedy wireless connection to the internet.
Uninterrupted connectivity: High-performing WiFi networks should also offer an excellent user experience, and uninterrupted connectivity is an essential part of it. When going from room to room, the last thing you want is for your WiFi connection to drop for a few seconds because you left the range of one WiFi network and entered within the range of another one. Mesh networks solve this problem by wirelessly connecting together multiple routers (called nodes), arranging them in a mesh topology. Modern mesh WiFi systems are so easy to set up that even complete beginners can get them up and running in just a few minutes.
State-of-the-art security: No WiFi network will maintain its performance unless it’s secured with a strong password and robust encryption. Unsecured networks are a very common target of hackers, who don’t hesitate to take advantage of any opportunity to steal sensitive information and use it for their own personal gain. A WiFi signal analyzer can tell you if your WiFi network is using the latest security standard (WPA3), and you can also use it to determine how secure are other networks in your location.

What Is WiFi Analysis?

Any modern home isn’t modern without a wireless router. But with at least one wireless router in nearly every home, the WiFi radio spectrum can get cluttered pretty easily.

Most wireless routers use the 2.4 GHz radio band to transmit data. This radio band is divided into multiple channels, which are like the lines on the highway. In North America, the 2.4 GHz radio band is divided into exactly 11 channels, with channels 1, 6, and 11 being the only channels that don’t overlap with other channels.

In theory, 11 channels should be more than enough even for densely populated urban areas, but, in reality, people seldom change the default configuration of their wireless router, which results in a situation where too many wireless routers transmit data on the same channel.

WiFi analysis performed using a wireless network analyzer can reveal which WiFi channels are used the least and provide plenty other information necessary for comprehensive WiFi optimization. WiFi analysis isn’t hard to do, provided you use a good WiFi analyzer app, and its benefits are plentiful.
