Modern users rarely think about how their device connects to the internet until they encounter a speed or stability issue. At such moments, detailed information about the current wireless connection becomes urgently needed. This may be necessary for setting up a game server, troubleshooting interference, or simply to find out who else is using your network.
There are many ways to obtain this data, from standard operating system settings to specialized software. It's important to understand that network information This includes not only the username and password, but also IP addresses, subnet mask, DNS servers, and the adapter's physical address. In this article, we'll cover all available methods for different platforms.
Getting Wi-Fi information in Windows
The Windows operating system provides sufficient tools for basic connection analysis. The easiest way is to use the graphical interface. Right-click the network icon in the system tray and select "Network & Internet settings." This displays the connection status, but for a more in-depth analysis, you need to go further.
For more detailed information, including the router's MAC address (BSSID) and security type, go to the Network and Sharing Center. Click on your connection name (blue link), then click the Details button. In the window that opens, you'll see a list of all parameters, including IPv4 address, default gateway and IP lease time.
However, the most powerful tool is the command line. It allows you to see hidden parameters that are not visible in the GUI. For example, using the command netsh wlan show interfaces You can find out the signal strength in percent, the radio type (802.11ac/n/ax), and the current channel the access point is operating on. This is critical when choosing a location for installing the router.
If you need to find out the password for an already saved network, in Windows this can be done through the command line with administrator rights. The command netsh wlan show profile name="Network_Name" key=clear will display all profile parameters, including the security key in clear text in the "Key content" field.
- 📡 netsh wlan show all — displays a complete summary of all wireless profiles and their settings.
- 🔍 ipconfig /all — shows detailed information about all network adapters, including DNS and physical address.
- ⚙️ systeminfo — contains general information about the system, including network cards and their drivers.
Network analysis on Android and iOS
Mobile operating systems are more closed, but they still allow access to important settings. On Android, the path may vary depending on the manufacturer's shell (MIUI, OneUI, Stock Android). Usually, it's enough to go to Settings → Wi-Fi and click on the name of the active network or the gear icon next to it.
In the menu that opens, you'll see the device's IP address, MAC address, connection speed (link), and gateway information. Some smartphones have a hidden testing menu. If you dial the code ##4636##, you can access the engineering menu, where the "Wi-Fi Information" tab is available. It displays RSSI (signal level in dBm), channel frequency and bandwidth.
What does RSSI mean?
RSSI (Received Signal Strength Indicator) is an indicator of the received signal strength. Values closer to 0 are better: -30 dBm is an ideal signal from a router, -80 dBm is a barely usable internet connection at the limit of range.
iOS (iPhone, iPad) users have a less flexible interface in the default settings. In the section Settings → Wi-Fi Click the blue "i" icon next to the network. This displays the IP address, subnet mask, router address, and DNS. For more detailed information, such as noise level or a detailed channel list, you'll need to use third-party utilities, as Apple restricts access to Wi-Fi chip data for apps from the App Store.
However, even standard tools are often sufficient for diagnostics. If you see a low connection speed (Link Speed) even though the router is nearby, it's possible the device is connecting on 2.4 GHz instead of 5 GHz, or a noisy channel is selected.
- 📱 On Android, use apps like WiFi Analyzer to plot a channel graph.
- 🍏 Try the app on iOS AirPort or Fing to scan the network.
- 🔒 Hide SSID is a feature that makes the network invisible to regular users, but does not hide it from sniffers.
⚠️ Attention: Mobile operating system interfaces are frequently updated. The layout of menu items may change with the release of new versions of Android or iOS. If you don't find the settings described, try searching through your phone's settings.
Using the Command Prompt and PowerShell
For advanced users and system administrators, the command line (CMD) and PowerShell offer limitless possibilities. In Windows PowerShell, cmdlets Get-NetIPConfiguration provides structured information about network interfaces. This is a more modern and readable alternative to the good old ipconfig.
To find out what networks have been previously used on a computer, enter the command netsh wlan show profiles. This will list all saved profiles. This is useful if you want to delete an old profile or view its settings. To delete a profile, use the command netsh wlan delete profile name="Name".
netsh wlan show profile name="Home_WiFi" key=clearIn Linux distributions the main tool is iwconfig or newer iw. Team iw dev wlan0 link will show the connection status, signal, and data transfer rate (tx bitrate). On macOS, use the utility networksetup or the hidden Wireless Diagnostics mode, which is accessed by holding down the Option key while clicking on the Wi-Fi icon.
A single syntax error can reset your network settings or delete important profiles. Always double-check commands before entering them, especially if you copy them from the internet.
- 💻
ipconfig /releaseAndipconfig /renew- Forces a reset and requests a new IP address from the router. - 🧹
netsh wlan delete profile name="*"- deletes all saved Wi-Fi profiles (dangerous!). - 📡
iwlist scanning— (Linux) scans available networks and displays their frequencies and signal quality.
Diagnostics via the router's web interface
The most comprehensive source of network information is the router itself. Access the control panel through a browser using the gateway IP address (usually 192.168.0.1 or 192.168.1.1). Here you see the picture from the administrator's perspective: who is connected, CPU load, temperature, and WAN port status.
The "Status" or "Network Map" section displays the connection type to your ISP (PPPoE, DHCP, Static IP), the assigned external IP address, and the uptime (the time it takes to operate without rebooting). In the Wireless section, you can see the current channel, bandwidth (20/40/80 MHz), and the number of active clients. This is the only place where you can forcefully disconnect from a specific device or limit its speed.
☑️ Checking router settings
Event logs are also often available in the web interface. They show unauthorized connection attempts, authorization errors, and system messages. If your internet connection goes down, these logs can help you pinpoint the cause: a disconnected ISP line or a modem reboot.
Keep in mind that changes to your router settings are applied immediately and may interrupt your current connection. If you change your wireless network settings (SSID, password, channel), the device you're making the changes from will disconnect. You'll have to reconnect with the new settings.
| Parameter | Description | Where does it influence? |
|---|---|---|
| SSID | The name of the wireless network that appears when searching | Network identification by the user |
| BSSID | MAC address of the access point (router) | Technical identification of equipment |
| Channel | Frequency data transmission channel | Speed and stability, no interference |
| Security | Encryption protocol (WPA2, WPA3) | Security of transmitted data |
Specialized software for analysis
When standard means are not enough, professional snails come to the rescue. WiFi Analyzer (available in the Microsoft Store and on Android) visualizes the airwaves. It displays a channel load chart, helping you choose the clearest one for your router. This is especially useful in apartment buildings, where dozens of networks create a confusing signal mix.
For Windows, a great tool is Acrylic Wi-Fi HomeIt displays not only channels but also hidden networks, security levels, and access point manufacturers. The program can also plot signal changes over time, which is useful for finding "dead zones" in an apartment.
macOS users should pay attention to the built-in "Wireless Diagnostics" utility. To open it, hold down the Option key and click the Wi-Fi icon in the menu bar, then select "Open Wireless Diagnostics." From the "Window" menu, select "Scan." This powerful tool displays noise, signal, and recommended channels.
Use third-party software with caution. Download programs only from the developers' official websites. Utilities for "hacking" or "boosting" a signal often contain malicious code. It's impossible to actually boost a signal programmatically; you can only optimize the settings.
- 📊 Heatmap — the function of constructing a thermal map of indoor coverage.
- 🛡️ WPS Audit — checking the network vulnerability to attacks via WPS (often found in analyzers).
- 📡 Spectrum Analyzer — frequency spectrum analysis to find sources of interference (microwaves, Bluetooth).
Security and hidden parameters
Knowing your network information isn't just convenient, it's also a security issue. Knowing your IP address and open ports helps you assess risks. You can check which ports are open on your device on the local network using the command netstat -anIf you see many established connections to strange IP addresses, this is a reason to check for viruses.
It is also important to pay attention to the encryption protocol. If the network information indicates WEP or WPA/TKIP, your network can be hacked in a matter of minutes. Modern standards require the use of WPA2-AES or WPA3Information about the current protocol can be easily found in the wireless connection properties.
⚠️ Attention: Never connect to public Wi-Fi networks without a VPN if you plan to transmit confidential data. On an open network, anyone with sniffing skills can intercept your traffic.
Another hidden parameter is the MTU (Maximum Transmission Unit). An incorrect MTU value can cause some websites to fail to open, even though internet access is possible. The default value for Ethernet is 1500, while PPPoE often requires 1492. You can change it through the registry or the command line.
Regularly monitoring the list of connected devices will help identify uninvited guests. Compare the MAC addresses on your router with those of known devices. If you find an unknown device, immediately change your Wi-Fi password and enable MAC address filtering.
How to hide your MAC address?
Modern versions of iOS and Android have a feature called "Private Wi-Fi Address" or "Use Random MAC Address." This prevents your movements between access points from being tracked, but it can complicate setting up MAC filtering on your router.
Frequently Asked Questions (FAQ)
How do I find out my Wi-Fi password if I'm already connected but don't remember it?
On Windows, this can be done via the command line with the command netsh wlan show profile name="Name" key=clearOn Android (without root access), viewing the password in plain text is difficult, but you can generate a QR code to connect another device through the network settings. On an iPhone, viewing the password is only possible if the device is jailbroken or if you have a Mac with the key saved in iCloud.
What does it mean if the signal level is -70 dBm?
This is a boundary value. A signal of -30 to -50 dBm is considered excellent, while -60 to -70 dBm is considered good/average, sufficient for web surfing. Values below -80 dBm indicate a very weak signal, possibly resulting in connection drops and low speeds. For stable video playback or gaming, a signal of at least -65 dBm is recommended.
Why does the router show a speed of 300 Mbps, but the Internet is slower?
The speed shown in Wi-Fi properties (link) is the connection speed between your device and the router over the air. Actual internet speed is limited by your provider's plan. Furthermore, over the air, up to 40-50% of the theoretical speed is always lost due to protocol overhead and interference.
Is it possible to find out who exactly is using my Wi-Fi?
Yes, through the router's web interface in the "Client List" or "DHCP Server" section. The IP and MAC addresses of all connected devices are displayed there. The device name can be hidden or replaced with "Unknown," but the MAC address is unique. The first six characters of the MAC address can be used to identify the device manufacturer (e.g., Apple, Samsung, Intel).
How to reset all network settings in Windows?
Windows 10 and 11 have a built-in reset feature. Go to Settings → Network & Internet → Advanced network settings → Network resetThis will delete all saved Wi-Fi profiles, reset the TCP/IP stack, and reboot the computer. Use this if other diagnostic methods fail.
