What is a WiFi hotspot called: technical terms and settings

Many users find themselves in a situation where they need to set up a home network, but the technical language of the instructions leaves them baffled. The question of what exactly a WiFi access point is called often leads to confusion between the visible network name and its physical address. In everyday life, we're accustomed to using the simple name displayed on our smartphone screen when searching for a connection, but this isn't enough for equipment administration.

Understanding the differences between SSID, BSSID Understanding the IP address and MAC address is critical when configuring complex equipment, such as smart home systems or corporate gateways. Misidentifying these parameters can result in devices failing to connect or weakening perimeter security. Let's clarify the terminology so you can confidently manage your network environment.

Technical documentation from providers and equipment manufacturers uses strictly defined naming standards. Knowing these terms will allow you to quickly resolve connection issues and correctly configure your router's security settings without the help of specialists.

SSID: The visible name of the wireless network

The primary identifier that every user encounters is called SSID (Service Set Identifier). This is an alphanumeric string that appears in the list of available networks on your laptop or phone. This is the "name" you choose to connect to the internet. By default, manufacturers often set a name that includes the device's brand, for example, TP-Link_2G_4A3B or Keenetic-1234.

Technically, an SSID isn't an address in the traditional sense; it's more of a label that allows devices to find each other over the air. This identifier can be up to 32 bytes long, allowing for fairly long and complex names. It's important to understand that case is important: network HomeWiFi and the network homewifi for the device there will be two different access points.

⚠️ Warning: Using special characters (such as quotation marks, commas, or currency symbols) in the SSID may prevent some older devices (such as printers and IoT light bulbs) from seeing or connecting to the network.

When setting up your router for the first time, it's highly recommended to change the default name to a unique one. This will not only help you quickly find your network in an apartment building where the airwaves are overloaded with neighbors' signals, but also hide your equipment model from potential intruders.

BSSID: Physical address of the access point

If SSID is a name that we come up with ourselves, then BSSID A Basic Service Set Identifier (BSSID) is a hard-coded identifier. Essentially, a BSSID is the MAC address of a wireless access point's radio module. Unlike a variable network name, this address is unique to every device worldwide and is assigned at the factory.

The BSSID entry format is six pairs of hexadecimal digits separated by colons, for example: 00:1A:2B:3C:4D:5EIn typical home settings, users rarely need to manually enter this parameter. However, the BSSID plays a key role when roaming between multiple access points or when configuring MAC address filtering for enhanced security.

In situations where a single router broadcasts multiple networks (guest and main) or operates in two bands (2.4 GHz and 5 GHz), each virtual interface will have its own unique BSSID, even if the SSID (name) is the same. This allows client devices to distinguish between specific radio channels and switch between them without losing the connection.

For system administrators, the BSSID is a key diagnostic tool. By analyzing association tables, one can pinpoint which physical antenna a client is connected to and assess the signal quality from that specific module, rather than the entire logical network.

Differences between SSID, ESSID and BSSID

As you delve deeper into the IEEE 802.11 networking standards, you may come across the term ESSID (Extended Service Set Identifier). In practice, for the average user, the ESSID and SSID are the same visible network name. The difference lies in the architecture: an SSID identifies a single cell (BSS), while an ESSID unites multiple access points into a single logical network with a common name.

When you're in a large office or shopping mall and see one network name, but your phone automatically switches between different routers as you move, you're using an ESS. In this case, each access point will have a different BSSID, but the ESSID will be shared. This ensures seamless roaming.

For a home network, which typically uses a single router, these distinctions are often ignored, and all three terms can be used interchangeably. However, when expanding coverage with repeaters or mesh systems, understanding this distinction becomes crucial for proper configuration.

How to find and change the access point name

To change the name of your network, you need to log into the router's web interface. Typically, you need to enter the gateway IP address (often 192.168.0.1 or 192.168.1.1) in the browser's address bar. After entering your username and password (found on the sticker on the bottom of the device), the control panel will open.

Wireless settings are usually located in the Wireless or WiFiThere you will find a field. SSID Name or simply Network Name. After entering the desired name, don't forget to save the changes by clicking the button Apply or SaveThe router will reboot the wireless module, and the devices will need to be reconnected.

• 📱 Via mobile app: Modern routers (Xiaomi, Keenetic, TP-Link) allow you to change the SSID through a proprietary app on your smartphone without accessing the browser version.
• 💻 Via command line (for advanced users): In corporate equipment (MikroTik, Ubiquiti), settings are often made via the CLI command /interface wireless set wlan1 ssid="NewName".
• 🔌 Factory reset: If you have forgotten your admin password, the only way to regain access is to click the button Reset on the case, but this will also return the standard network name.
