About the choice of the Wi-Fi channel, not a few articles and detailed manuals have been written. The result is always the same - the freer the channel, the more stable, stronger and more stable the signal. For Windows 10, the preview version of the most popular radio channel monitoring utility, WiFi Analyzer, has finally been released. Now to know the free range - easy
The Windows version assumes that you already have Windows 10 on board, so you need to upgrade. On phones running Windows phone The utility will not rise for the same reason - a dozen are needed, but since it has not yet come out, you can install it only on personal computers.
A huge influence on the signal have external factors. Walls, electrical appliances, other Wi-Fi networks. Even the material of your interior door can play a big role in the capacity of the channel. Their detailed description can be found at http://optim-yug.ru/. There you can ask the price and choose for yourself a good interior door.

When the program starts, a window opens:
1 - Receiver sensitivity.For my adapter is 46 dBm (decibel-milliwatts). Sensitivity in this aspect - This is the minimum signal level at which Wi-Fi will work. The closer you are to the access point (router) - the lower the sensitivity. The farther away - the receiver needs to “plow” more in order to correctly process the signal. A value greater than -85 dBm is considered unsatisfactory for normal operation.
If any of the icons are on, then:
2 - Signal quality
3 - Basic network settings. Here we will see the name (SSID) of the network to which we are connected, the frequency and the current channel.
4 — Bssid - our MAC address wireless network.
Separately about the BSSID - what is it?
Basic service set identification (BSSID) -unique number (mac address) of our wireless network. If your router supports MBSSID technology, then you can configure up to several access points on a single router. Those. multiple networks within a single Wi-Fi network. One SSID can have up to four BSSIDs, respectively, each will have its own MAC address. You can peep it in command line by team netsh wlan show networks mode = bssid . Here's what it looks like:
What is it for? For different security policies (guest network / network for staff), different routing policies (static IP, DHCP), and so on. Yes, you can buy a second access point and configure everything there, but this is an additional financial cost + an extra device on the network.
How to choose the desired channel?
Go to the tab "Analyze" at the top of the program and see the following picture:
Every arc is someone's Wi-Fi networkaccordingly, on the left, the sensor sensitivity (signal level), below - the channels. Thus, you can track which of the channels "grazes" the greatest number of access points. To make it clearer, try turning on the SSID display. So the picture becomes even clearer:
Please note that the program itself recommends which channel is most beneficial for our laptop / pc:
Thus, we found out the most “noisy” air, looked at the receiver sensitivity and found out that the most free radio channel for our device is 12
What else can you do?
If the signal between the router and the laptop still leaves much to be desired, and the distance between them is quite small (1-3 meters), then it is recommended to remove the router from the walls to eliminate interference from neighboring devices (this may not necessarily be a router). Try to put the router in different points of your apartment - even minor movements around the room can give up to 90% (!) Signal improvements and, accordingly, speed via Wi-Fi connection
Chip Opinion: Google promises a simple solution for as much coverage as possible with the WLAN network of every home. Using the system Google wifi the Internet giant is really able to seriously improve the hardware. The system is very easy to configure and offers high performance even in the most remote corners of the apartment.
You can get the Google WiFi system with one, two or three "units" - their number depends on the size of your home. In the case of the kit we tested, we are talking about two “units” of Google WiFi, which together must provide full coverage with a WLAN signal of an apartment of up to 100 square meters.
Compact and productive
Wrapped in white plastic clothes, the Google WiFi system thanks to a quad-core processor and 512 MB random access memory has a large enough power. At the same time, four antennas are integrated into Google WiFi - two for the 2.4-band and two for 5-GHz. According to the manufacturer, the system is able to work simultaneously in two bands and thus, in theory, reach a maximum data transfer rate of up to 1200 Mbps.
With the help of 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 its encryption method, which is a modern standard.
Google WiFi: expands depending on the size of the apartment
All through the app
The WLAN system from Google is configured exclusively through the application (Google WiFi), which is installed on a smartphone or tablet. In this case, all user actions on setting are accompanied by a really good assistant assistant. Even without his prompts, you must first connect one of the “units” of Google WiFi to a power outlet and your Internet connection (existing modem router or modem) —through the integrated modem, Google WiFi will not be available.
Then you need to run on your smartphone a configuration application with an assistant. Via Bluetooth, the application will find your “primary unit” of Google WiFi. Then use the camera to scan the QR code located on the back of Google WiFi, after which 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 easy: plug into a power outlet, hold a smartphone with Bluetooth turned on for a while, scan a QR code - and that's it, too!
Something more, something less: the Google WiFi app won't share much more information You can't do much
The application does not offer a really large number of options for customization. You can prioritize requests from specific users, create a guest network, add new Google WiFi devices, test the speed of your Internet connection, and use a couple more functions.
Moreover, it is the connection tests that show “heterogeneous” results: if the net speed test of the Internet connection (measured on the LAN port of the primary “one”) gives the result in the “real” numbers, the quality of communication between the individual “units” of the system is evaluated by the application only by school marks .
Everything is displayed visually, intuitively and graphically designed accordingly. But all this is not for those users who are engaged in network settings at a professional level! In particular, it would be in vain here to search for the possibility of manually setting up WLAN channels or changing other settings on the network.
The best WLAN network everywhere!
In everyday use, you really will not notice when your device will “change” one “unit” of Google WiFi to another - in this sense, the network is absolutely homogeneous. So, in our test apartment, we could not find a single “narrow” place, which previously met in one or the other corner - the system imperceptibly and constantly connects you to the Google WiFi device you need at the right time.
Now everywhere the signal level is really very good, which is marked not only by subjective sensations, but also by the results of measurements of the Google WiFi application. Perhaps the 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 your home. According to the results of the practical test, we can confirm that it works really well. At the same time, setting up the Orbi system is also very simple.
It is often necessary to quickly check. wifi level signal to select the most free channel with good reception quality. For this task, the best possible simple android application Wifi Analyzer.
With it, you can easily not only determine the free channels, but also check the quality wi-Fi reception at various places apartments or cafes 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. In case of their intersection on the chart, this will be clearly displayed.
You can also see the “rating” of the channels, by the type of any star ratings, which clearly shows how appropriate the choice of one or another of them is at the moment. Another feature of the application is force analysis. wi-Fi signal. First you need to choose which wireless network you are checking for, and then watch the reception level, while nothing prevents you from moving around the area or checking the change in reception quality depending on the location of the router.
It would also be nice to add our interest in WiFi network can be not only in passive analysis. With help mobile phone You can also try to find a password for a wireless access point. For this you need an application called WIBR.
WIBR is a unique application with the help of which you will be able to hack a neighbor's Wi-Fi and use its Internet for free. This is not a joke, WIBR works on the principle of automatic selection of passwords (brutes) to Wi Fi, and if the password is simple, then the probability of selecting a password is close to 100 percent.
Vibr supports hacking multiple Wi-Fi networks at once, and displays 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 downloading your own dictionaries, for this you need to download them (or write all the options yourself in a notebook possible passwords and save in txt format), specify the path in the program itself. Especially for our users, we added more than 10 dictionaries with the most common passwords.
