When it comes to identifying a wireless network, users often get confused by the terminology, as the term "ID" can refer to completely different parameters depending on the context. In the world of networking, the term "ID" is most often used to describe MAC address physical device or BSSID (Basic Service Set Identifier), which is the access point's MAC address. These values are required for setting up MAC address filtering, roaming, or precise indoor positioning.
For the average user, knowing your access point's unique identifier may be necessary when trying to connect a new device that is tightly bound to a specific piece of hardware, or when setting up complex equipment such as IP cameras or smart plugs. Without entering this information correctly, the gadget will simply not be able to find the network or will be rejected by the router's security system, even if the password is entered correctly.
In this article, we'll take a detailed look at how to find these hidden parameters on various operating systems, using both the graphical interface and the command line. You'll learn to distinguish between the SSID (network name) and the actual technical identifier, and understand why these values may change when randomization is enabled.
Differences between SSID, BSSID and MAC address
The first thing you need to understand to successfully troubleshoot a network is the fundamental difference between a network's visible name and its technical identifier. SSID (Service Set Identifier) is the name you see in the list of available networks, such as "Home_WiFi" or "TP-Link_5G." This name can be changed to anything convenient, and it serves only as a label for users.
Unlike a changeable name, BSSID A BSSID is a unique 48-bit identifier whose structure completely replicates the MAC address of a router's wireless interface. The BSSID is used by client network cards to uniquely identify a specific access point, especially in situations where multiple routers with the same SSID are broadcasting in the same area.
It's important to understand that BSSID and MAC address in the Wi-Fi context are essentially the same thing, but the term BSSID applies specifically to the wireless segment of the network. If you configure MAC address cloning on another router, it will appear to client devices as the same physical access point, even if the SSID is different.
- 📡 SSID — a human-readable network name that can be changed infinitely.
- 🆔 BSSID — unique technical identifier of the access point (format XX:XX:XX:XX:XX:XX).
- 💻 MAC address — the "hardware" address of the network card, which in the Wi-Fi context acts as BSSID.
⚠️ Attention: Modern routers that support both 2.4 GHz and 5 GHz bands may use the "Smart Connect" feature, which combines the bands under a single name. In this case, you'll effectively have two different BSSIDs (one for each frequency band), although the network name (SSID) will remain the same.
Finding BSSID and MAC Address on Android
Mobile devices running Android Provides fairly detailed information about the current connection, but access to this information depends on the operating system version. Starting with Android 10, Google has strengthened its privacy policies by implementing MAC address randomization, which can confuse inexperienced users trying to find the router's permanent identifier.
To find out the BSSID of your current network, go to Settings → Connections → Wi-FiClick on the name of your active network or the gear icon next to it. In the menu that opens, select "View more" or scroll down to the "Network details" section. There you will see a field BSSID, which is the desired MAC address of the access point.
It's worth noting that if you use the "Randomized MAC" feature to connect, your phone will generate a temporary address for itself, but the router's BSSID will remain unchanged and visible in the same menu. This is critical for those setting up whitelisted access.
For more detailed technical information, including signal strength (RSSI) and channel frequency, you can use the hidden testing menu. Enter the code in the dialer ##4636## (doesn't work on all firmware versions), go to the "Wi-Fi information" section and select "Wi-Fi status". The full BSSID and the current gateway IP address.
Finding the Network ID in Windows
operating system Windows provides several ways to obtain information about your wireless adapter and connection point. The fastest and most reliable method, which works on all versions of Windows from Windows 7 to Windows 11, is using the command line. The graphical interface may hide some details, while the console provides the raw data.
Open the command prompt by typing cmd in the Start menu search and run the command:
netsh wlan show interfacesIn the command output, find the line BSSIDThis is the MAC address of your access point. It will also show SSID (network name), radio type (e.g., 802.11ac or 802.11ax), and signal strength as a percentage. If you're connected to a 5 GHz network, make sure you're looking at the currently active interface if you have more than one.
☑️ Data verification in Windows
The alternative method via the graphical interface requires more steps. Click Win + R, enter ncpa.cpl and press Enter. Right-click on the "Wireless Network" adapter, select "Status," and then "Details." However, this often only displays the physical address of your adapter, not your router, so the method netsh is preferred for obtaining the BSSID.
Using utilities for macOS and iOS
In the ecosystem Apple Accessing technical details of a Wi-Fi connection is somewhat limited by security policies, especially on mobile devices. On an iPhone or iPad, you won't see the BSSID field in the standard Settings menu. To obtain this information on iOS, you'll need to install third-party utilities, such as AirPort Utility from Apple, and enabling a special debugging mode.
On computers macOS The situation is much simpler thanks to the built-in diagnostic utility. Hold down the key Option (Alt) on your keyboard and simultaneously left-click on the Wi-Fi icon in the menu bar (at the top of the screen). An expanded menu will open, where you'll immediately see BSSID, channel, signal strength (RSSI) and noise.
A more in-depth analysis can be performed using Wireless Diagnostics. Launch it via Spotlight (Cmd + Space), then select Utilities from the Window menu (Window → Utilities). The Info tab will display detailed statistics on the current connection, including the MAC addresses of all visible access points within range.
⚠️ Attention: On Apple devices with the "Private Wi-Fi Address" feature enabled, your iPhone or Mac will use a random MAC address each time it connects to a new network. This doesn't change the router's BSSID, but it can cause problems if the router is configured to filter by client MAC addresses.
Network Parameter Correspondence Table
To help you organize your knowledge of wireless network parameters, below is a table explaining the key characteristics found in diagnostic utilities. Understanding these values will help you fine-tune your equipment and troubleshoot connection issues.
| Parameter | Description | Value format | Changeability |
|---|---|---|---|
| SSID | The name of the wireless network visible to the user | Text (up to 32 characters) | Full |
| BSSID | MAC address of the access point (router) | HEX (XX:XX:XX:XX:XX:XX) | Fixed (usually) |
| Channel | Broadcast frequency channel | Number (1-14 or 36-165) | Full |
| RSSI | Received signal level | Negative number (dBm) | Dynamic |
| Security | Data encryption type | WPA2, WPA3, WEP | Full |
Pay attention to the parameter RSSI (Received Signal Strength Indicator). It's measured in negative decibel-milliwatts (dBm). The closer the value is to zero, the better the signal. For example, -40 dBm is an excellent signal near the router, while -85 dBm is an area of poor reception where connection drops are possible.
The type of security also plays an important role. Modern standards WPA3 Provides better protection against password attacks than the outdated WPA2, but not all older devices support the new protocol. When changing the encryption type, all devices will need to be reconnected.
Why is RSSI always negative?
The RSSI value is negative because it is measured relative to 1 milliwatt. Since a Wi-Fi signal is very weak (fractions of a milliwatt), the logarithmic value is always negative. -100 dBm means a signal 100 times weaker than -80 dBm.
Command line and advanced diagnostics
For network engineers and advanced users, the graphical interface is often redundant or insufficiently informative. Using the command line allows you not only to find the ID, but also to scan the airwaves, find clear channels, and identify sources of interference. On Linux and macOS, a utility is used for this purpose. iwlist or airport.
On Linux distributions the command iwlist wlan0 scan (Where wlan0 (Your interface name) will list all available networks with their BSSID, frequency, signal quality, and supported speeds. This is an indispensable tool when planning Wi-Fi coverage in an office or large home.
sudo iwlist wlan0 scan | grep -E "Cell|ESSID|Frequency|Quality"On Windows, the equivalent is the command netsh wlan show networks mode=bssidIt will display a list of all networks within range and, for each one, all available BSSIDs (if there are multiple, such as repeaters). This allows you to understand which physical access point the device will connect to at any given moment.
Issues with randomization and privacy
Modern operating systems are actively implementing privacy protection features that can mask real identifiers. MAC address randomization (used both by the client and sometimes by scanning services) creates temporary addresses. This means that if you try to filter a device by MAC address in the router settings, and randomization is enabled on your phone, the filter will fail.
In such cases, you should either disable randomization for trusted networks (select "Use device MAC address" in the Wi-Fi settings of a specific network on your phone), or use other identification methods, such as a static IP or hostname, although the latter is less reliable.
Also worth mentioning are "hidden networks" (SSIDs), which don't broadcast their names. However, their BSSID and other parameters (channel, encryption) remain visible to any airspace scanner. Hiding the SSID isn't a security measure; it merely creates inconvenience for legitimate users, as the BSSID is still easily read by any sniffer.
⚠️ Attention: Router and operating system settings interfaces are subject to update. The location of menu items or function names (e.g., "Private Address" instead of "MAC Randomization") may differ depending on the firmware or OS version. Always consult the official documentation from your device manufacturer if you cannot find a specific option.
Frequently Asked Questions (FAQ)
Is it possible to change the BSSID of a router?
Technically, the BSSID is tied to the MAC address of the wireless chip, which is programmed at the factory. However, many modern routers (especially those with firmware OpenWrt, DD-WRT or in advanced settings Keenetic, MikroTik) allow you to clone a MAC address or set virtual BSSIDs for guest networks. For a regular user, this value is considered permanent.
Why are there multiple BSSIDs with the same name in the list of networks?
This is normal if you have a mesh system configured or multiple routers operating in access point mode with the same SSID. Each physical unit (the main router and satellites) has its own unique BSSID. The client device automatically chooses which one to connect to based on the signal strength.
How to find out your neighbor's Wi-Fi ID?
You can see the BSSID and SSID of any open network in range through standard OS tools or utilities like inSSIDer or WiFi AnalyzerHowever, obtaining a password or attempting to access someone else's network without the owner's permission is illegal and violates the principles of online ethics.
Does changing BSSID affect internet speed?
The BSSID itself is simply an identifier and doesn't affect speed. However, if you clone the MAC address (BSSID) of an old router to a new one without rebinding it with your ISP, the internet may not work if your ISP uses MAC address binding. In this case, you'll need to either clone the address in the WAN settings or provide the new address to your ISP.
