Modern smartphones based on Android They have powerful network diagnostic tools that many users don't even know about. Often, when the internet is slow or the connection is frequently interrupted, the first thing you want to do is check your connection parameters. Instead of guessing about the cause of instability, it's best to immediately consult the technical data hidden deep within the operating system's menus.
Understanding your router's frequency can dramatically change your wireless experience. Many people still use the crowded 2.4 GHz band, even though their devices support the faster and more stable 5 GHz standard. Information about the current connection available to anyone who knows where to look in the smartphone interface.
In this article, we'll cover in detail all the methods for obtaining comprehensive information about your Wi-Fi network. You'll learn how to determine not only the access point name, but also its IP address, broadcast channel, security standard, and actual link speed. This knowledge will help you optimize your home network and troubleshoot most common coverage issues.
Checking basic information via the status bar and settings
The easiest way to get basic connection information is to look at the top of the screen. If you see a "6" next to the Wi-Fi signal icon, it means your device is connected to a router using a modern standard. Wi-Fi 6 (802.11ax)The absence of a number or the presence of other symbols may indicate older standards, such as 802.11n or 802.11ac.
For more detailed information, please go to the settings menu. The path may vary slightly depending on the manufacturer's shell (Samsung One UI, Xiaomi MIUI, Stock Android), but the logic remains the same. You need to open the "Network and Internet" or "Connections" section, where the current status is displayed.
Click on your network name or the arrow next to it to expand the detailed menu. Here you'll see the connection status, signal quality as a bar, and a "Manage" button or gear icon. This section also contains a button that opens a full technical connection map.
⚠️ Note: On some smartphone models with heavily customized skins, the interface may look different. If you don't find the options described, try searching through the settings by entering "Wi-Fi" or "Status."
How to determine whether your Android device is using 2.4 GHz or 5 GHz
One of the most important parameters that affects speed and stability is the frequency range. 2.4 GHz has better penetration through walls, but it is heavily congested by neighboring routers and household appliances. The range 5 GHz provides high speed, but passes through obstacles worse and has a shorter range.
To find out what frequency you're using, open the advanced Wi-Fi settings as described above. In the "Network Information" or "Details" menu, find the "Frequency" field. If it shows 2412–2472 MHz, you're in the 2.4 GHz band. Values of 5150–5800 MHz indicate a connection to the 5 GHz band.
Sometimes manufacturers hide this information in the standard interface. In this case, pay attention to the network name (SSID). Routers often append the suffix "_5G" or "_5GHz" to the 5GHz network name by default. If you see two networks with the same name, but one has "5G" appended, the choice is obvious.
Viewing the IP address of your router and gateway
Knowing the gateway IP address is necessary to log into the router's admin panel, where you can change the password, configure channels, or update the firmware. On Android, this information is available in the same network information menu where we looked for the frequency. Look for the line "Gateway" or "Router."
Most often the address looks like this 192.168.0.1 or 192.168.1.1This is the local address your router distributes within your home network. Knowing this, you can enter it into the address bar of any browser on your phone and access the device's management interface.
Your network IP address and subnet mask are also displayed here. This information may be needed for setting up port forwarding or connecting network printers and NAS storage. Make sure your IP address is in the same subnet as the gateway.
Typical gateway addresses:192.168.0.1
192.168.1.1
192.168.31.1 (often used by Xiaomi)
192.168.10.1 (often from ASUS)
Using the Wi-Fi Analyzer app for deep diagnostics
If standard system tools are not enough, specialized utilities come to the rescue. Application Wi-Fi Analyzer (or its analogues, such as Fritz!App WLAN or Network Analyzer) allows you to visualize the broadcast. It displays a channel load chart, which is critical for choosing the least noisy band.
In these apps, you'll see not only your network but also all neighboring ones. Graphs will show which channels overlap. For example, in the 2.4 GHz band, only channels 1, 6, and 11 are non-overlapping. If your router is on channel 3, it will interfere with both channels 1 and 6 of your neighbors.
Particular attention should be paid to the function for measuring signal speed at different points in the apartment. By walking through the rooms with your phone, you can create a heatmap of the coverage. This will help you identify "dead zones" where the signal drops below a critical level. -85 dBm.

Comparison table of Wi-Fi standards and their characteristics
Understanding the differences between wireless generations helps you assess the potential of your equipment. Below is a comparison table of the main standards you might encounter in your phone's settings.
| Standard | Maximum speed | Frequency | Peculiarities |
|---|---|---|---|
| 802.11n (Wi-Fi 4) | up to 600 Mbps | 2.4 / 5 GHz | Basic standard, MIMO support |
| 802.11ac (Wi-Fi 5) | up to 6.9 Gbps | 5 GHz | High speed, wide channels |
| 802.11ax (Wi-Fi 6) | up to 9.6 Gbps | 2.4 / 5 / 6 GHz | Efficient operation in densely populated areas |
| 802.11be (Wi-Fi 7) | up to 40 Gbps | 2.4 / 5 / 6 GHz | The latest standard, ultra-low latency |
Please note that actual speed is always lower than theoretical due to protocol overhead, interference, and distance to the router. If your phone supports Wi-Fi 5, and the router only Wi-Fi 4, the connection will work according to the standards of the older device.
⚠️ Note: Settings interfaces and available data may change with Android version updates or changes in smartphone manufacturer policies. If you don't find a setting, check the official documentation for your device model.
Hidden features: engineering menu and ADB
For advanced users, there are ways to obtain technical information through hidden menus. Entering a special code into the dialer (for example, ##4636##) can open the testing menu. However, on modern versions of Android, access to this menu is often blocked by manufacturers for security reasons.
A more reliable, but more complex method is to use USB debugging and the command line. ADB (Android Debug Bridge)By connecting your phone to your computer, you can run a command that will display a detailed log of the Wi-Fi module's operation.
adb shell dumpsys wifi | grep -i"mNetworkInfo\|mWifiInfo"This command will return raw connection status data, including RSSI (signal strength), link speed, and the access point's MAC address. This method is useful for accurately determining whether your ISP is throttling your speed or whether there are issues with your phone's drivers.
What is RSSI and why is it negative?
RSSI (Received Signal Strength Indicator) is an indicator of the received signal strength. It is measured in dBm and is always negative. The closer the value is to zero, the better the signal. For example, -40 dBm is an excellent signal near the router, while -90 dBm is the limit of connection loss.
Common problems and their solutions based on the data obtained
Once you have channel and frequency information, you can troubleshoot common issues. If you see that you're on channel 6, but three of your neighbors are also on channel 6, your speed will drop. The solution is to go to your router settings and manually set a clear channel (1 or 11).
A common mistake is using a 40 MHz channel width in the crowded 2.4 GHz band. This leads to interference. Optimal width For 2.4 GHz, use 20 MHz. For 5 GHz, you can safely use 80 MHz or even 160 MHz, if your equipment allows it.
If your phone is constantly losing network connection, check the security standard. Outdated WEP or even WPA/TKIP may cause compatibility issues with new smartphones. It is recommended to use WPA2-AES or WPA3 for maximum compatibility and protection.
Why does my phone see the 5 GHz network but not connect?
This could be due to incompatible regional settings. Some routers use 5 GHz channels that are restricted in your region, causing your phone to block the connection. Another possible cause could be a weak signal: 5 GHz doesn't penetrate walls well, and at the edge of the coverage area, the phone might see the network but fail to authenticate due to high packet loss.
How to find out the MAC address of the phone's Wi-Fi module?
You can find your MAC address in the About Phone menu -> General -> Status or in the advanced Wi-Fi settings under Wi-Fi MAC Address. Please note that modern versions of Android use a randomized MAC address for each network to protect your privacy, rather than the actual physical address of your device.
Does the number of connected devices affect the speed?
Yes, it does have a direct impact. Wi-Fi is a half-duplex medium, meaning devices take turns speaking. The more devices connected to the router, the less time each one gets. If you have a large smart home, be sure to use a guest network or a separate router for IoT devices.
