Program for checking wifi signal strength. Wifi Analyzer is an application for analyzing WiFi signal in Android. Google WiFi test: good signal strength everywhere How to change automatic channel selection on a D-Link router

It is often necessary to quickly check the WiFi signal level in order to select the most free channel with good reception quality. For this task, a simple android app Wifi Analyzer.

With its help you can easily not only determine free channels, but also check the quality of Wi-Fi reception in different places of the apartment or cafe or view signal changes over time. After launching, a graph will be visible in the main window of the program, which will display visible wireless networks, the reception level and the channels on which they operate. If they intersect on the graph, this will be clearly displayed.

You can also look at the “rating” of channels, similar to any star ratings, which clearly shows how appropriate it is to choose one or another of them at the moment. Another feature of the application is the analysis of Wi-Fi signal strength. First, you will need to select for which wireless network the test is being performed, and then look at the reception level, while nothing prevents you from moving around the area or checking for changes in the quality of reception depending on the location of the router.

It would also not be amiss to add that our interest in WiFi networks may not only be in passive analysis. Using your mobile phone, you can also try to guess the password for a wireless access point. For this you will need an application called WIBR.

WIBR is a unique application with which you can hack your neighbor’s Wi-Fi and use his Internet for free. This is not a joke, WIBR works on the principle of automatically selecting passwords (brute force) for Wi-Fi, and if the password is simple, then the probability of guessing the password is close to 100 percent.

Vibr supports hacking several Wi-Fi networks at once, and shows information on one screen; when you click on one of the networks, you can see detailed statistics on the progress of work: the number of passwords per minute, how many password options have already been checked and how many are left.

The application supports loading your own dictionaries; to do this, you need to download them (or write all the possible passwords in notepad yourself and save them in txt format), specify the path in the program itself. Especially for our users, we have added more than 10 dictionaries with the most common passwords.

Today I’ll tell you about a very convenient and useful, but for some reason not yet well-known program for Android. The standard interface for searching and selecting a wireless network in Android cannot be called super informative. It is minimalistic and does not provide complete information about available WiFi points. Of course, maybe this icon with three signal levels is enough for someone, but there is a more convenient tool.

The main feature of WiFi Analyzer is a detailed display of the characteristics of each available WiFi points. It shows the exact signal level and channels on which this point operates.

Speaking of channels. Those who often have to configure wireless routers, or want to get the maximum signal quality from their router, will certainly like the ability to assess in a second the current situation with the occupancy of each WiFi channel, and set the least loaded ones for their device.

This application will also help in choosing the optimal location of the router in the office, apartment, and many other places. We leave our Android where the best signal quality is required, move the router, watch the signal quality change in the application, move the router. Repeat several times until you get the best result. If necessary, you can view signal level statistics from each available point.

For those who have not yet believed in its usefulness, I will give an example: through the standard Android interface you found 3 WiFi points with a signal level of 1 out of 3. Which one should you choose? With this program you can quickly assess the stability of even a low signal and select the most stable one.

A modern router is capable of scanning, checking whether the channel is free, or detecting excess signal. You can easily find a free window. Often the router firmware needs to be updated. Be careful! A power loss will interrupt the update process - instead of a Wi-Fi channel scanner, you will get a pile of scrap metal. The wireless access point can only be restored by an official service center or a technically savvy Kulibin.

Reasons for use

External interference reduces the speed of information flow. The bitrate drops noticeably. Try placing the router next to a working microwave oven - miracles will begin immediately. Interference is created by telephones, the sun, industrial and military facilities. Even USB interface 3 is a bit phony.

The channel scanner shows a list of available SSIDs, ignoring extraneous factors. Therefore, even a visually free niche sometimes works poorly. Consider the features software, building a home network.

If you notice a significant decrease in speed, use shielding and install directional antennas. Avoid crossing the beam line with your body. Microwave radiation is extremely harmful and is perfectly absorbed by the aqueous media of the body. Memory, intelligence, blood counts deteriorate, and sleep is disturbed. Immunity declines.

Router admin panel

Even the TP-Link 300 series can recognize network congestion. The updated firmware works wonders. The hardware itself begins to look for free channels, selecting (even automatically) free bands. The screen will show amazing things: neighbors literally occupied the same rooms. The smart device will monitor and show the status of networks for the user to check.

The screen clearly demonstrates the above. If the neighbors had bothered to regularly update the firmware, a check with an analyzer would have shown a fundamentally different picture.

Updating the router firmware

TP-Link firmware update option is the best. You immediately receive a ready-made tool for monitoring frequencies. Of course, the router is only capable of testing its own operating range (2.4; 5; 60 GHz).

1. Always take the firmware from the official website.
2. Make sure the following settings match:
   • Version.
   • Model.

The range of information varies greatly. Select a file by carefully studying the label. If the latter is missing, don't despair. Hardware and firmware versions are often indicated by the admin panel. Avoid being arbitrary: an experimental test can kill your equipment.

The software update procedure will require access. We believe that setting up the router itself is as simple as possible. As a last resort, perform a hard reset of the equipment by pressing the appropriate button.

1. Download the firmware file.
2. Record to PC.
3. Update the software via the cable by selecting the appropriate item in the router's admin panel.
4. The program requires a cable connection. Otherwise, a fatal crash is possible. Also take the trouble to ensure uninterrupted power supply.

inSSIDer

Software that can determine the load density of Wi-Fi channels is widely known. The strange name inSSIDer implies the device’s ability to catch SSIDs traveling on the air. The replacement for the aging NetStumbler will please mainly Windows users.

1. Visit the official project website metageek.com/products/.
2. Find the product you need.
3. Get ready to pay for the license.

The utility will provide the user with:

• Workload.
• Achievable speed.
• Writes available SSIDs (access point names).
• Will display specific parameters, such as RSSI, allowing you to analyze the signal.
• The program can catch MAC addresses.

Attention! The utility is powerless to track interference from household appliances, radio broadcasts, mobile phones, Bluetooth.

Free option

Considering what was said, Android users breathed a sigh of relief: they will have to definitely go through the channel numbers manually. However, there is another option. Yes! Acrylic WiFi (acrylicwifi.com/). The new product is free for now, please download it.

The utility collects:

1. SSID
2. BSSID
3. Channel congestion.
4. Security type and much more.

There are dozens for Windows, but such as WiFi SiStr unique of its kind. We are talking about the utmost simple application, which will allow you as a user to find out the signal strength of any Wi-Fi point. Of course, if it is within the reach of the sensor.

Interestingly, the wireless signal strength is shown digitally on the screen. After you click downloadWiFi SiStr and install the program, a small panel will appear on the desktop. You can place it in any part of the screen: bottom, top or even in the middle. It will show digital and graphical signal level values.

It often happens that a user cannot access a website for unknown reasons - especially if you are connected via Wi-Fi. There is another situation: the messaging client periodically interrupts the connection - you have to constantly reconnect. To solve this problem, just look at the signal status panel and make sure that it is sufficient for stable and fast Internet. If you have the WiFi SiStr program, then this is quite easy to do.

Features of the WiFi SiStr program:

• Flexible in setup. Despite the simple interface of the panel, you can even customize it. Just right-click on the status bar and a menu with settings will open.
• Convenient. You can monitor the signal level directly on the desktop of your PC or laptop.
• It does not consume a lot of system resources, it is not just small - it has a miniature size.
• For correct operation WiFi SiStr you will need .NETFramework versions 1.1 and higher.
• When started, it always minimizes to tray and does not interfere with computer work at all.

Chip's opinion: Google promises a simple solution for maximizing WLAN coverage in every home. With the help of the Google WiFi system, the Internet giant manages to really improve the hardware significantly. The system is very easy to set up and offers high performance even in the most remote corners of the apartment.

You can get a Google WiFi system with one, two or three “units” - the number depends on the size of your home. In the case of the kit we tested, we are talking about two Google WiFi “units”, which together should provide full WLAN signal coverage for an apartment of up to 100 square meters.

Compact and productive

Clad in white plastic, the Google WiFi system thanks to a quad-core processor and 512 MB random access memory has quite a lot of power. At the same time, four antennas are built into Google WiFi - two for the 2.4- and two for the 5-GHz band. According to the manufacturer, the system is capable of operating simultaneously in two bands and thus achieving, in theory, a maximum data transfer rate of up to 1200 Mbit/s.

Using Beamforming technology, the transmitter power can be further increased. In addition, two gigabit ports can be used for LAN or WAN connections. Google WiFi uses WPA2-PSK as an encryption method - this is a modern standard.

Google WiFi: expands depending on the size of the apartment

Everything through the app

Setting up a WLAN system from Google is done exclusively through an application (Google WiFi), which is installed on a smartphone or tablet. Moreover, all user setup actions are accompanied by a really good assistant. Even without his prompts, you must first connect one of the Google WiFi “units” to an electrical outlet and your Internet connection (your existing modem-router or modem) - Google WiFi will not be available through the integrated modem.

Next, you should launch the setup app on your smartphone, which is equipped with an assistant. Via Bluetooth, the app will find your Google WiFi "primary unit". Then use your camera to scan the QR code located on the back of Google WiFi and the WLAN connection should be established.

Now you give your network a name, then set a password to connect to it - and you're done! Adding a second “unit” is just as simple: plug it into a power outlet, keep your smartphone nearby with Bluetooth turned on for a while, scan the QR code - and you’re done!

In some ways more, in others less: the Google WiFi app won’t really share a lot of information

You can't do much

The application doesn't really offer a lot of customization options. You can prioritize requests from specific users, create a guest network, add new Google WiFi devices, test your Internet connection speed, and take advantage of a couple more features.

Moreover, it is the connection tests that show “heterogeneous” results: if a pure Internet connection speed test (measured using the LAN port of the primary “unit”) gives the result in “real” numbers, then the quality of communication between individual “units” of the system is assessed by the application only with school grades .

Everything is displayed clearly, intuitively and graphically designed accordingly. But all this is not for those users who configure networks at a professional level! In particular, it would be futile to search for the ability to manually install WLAN channels or change other settings on the network.

The best WLAN network everywhere!

In everyday use, you really won’t notice when your device “changes” one Google WiFi “unit” to another - in this sense, the network turns out to be absolutely homogeneous. So in our test apartment we were not able to detect a single “bottleneck” place, which were previously found in one corner or another - the system imperceptibly and constantly connects you to the one you need at a given moment Google device WiFi.

Now everywhere the signal level is really very good, which is noted not only by subjective sensations, but also by measurement results Google apps WiFi. Perhaps automatic channel selection works very well here.

Alternative: More Power - Netgear ORBI AC3000 (RBK50-100PES)

Netgear, too, with its WLAN system, which costs about 27,000 rubles, promises the best WLAN coverage in all corners of your apartment or home. Based on the results of our practical test, we can confirm that it works really well. At the same time, setting up the Orbi system is also very simple.
