![]() Mar 18, 2015 How to Join a Hidden Wi-Fi Network with No Broadcast SSID. Security by obscurity is reasonable but anyone super savvy can sniff channels and scan an. A wireless router can be configured not to broadcast its SSID. Sometimes you need to know all the available access points including the hidden ones so you can choose. • Access points: WiFi networks information (SSID/BSSID) and connected users. • Signal level: Signal quality charts for WiFi channels and detected devices. • Inventory: Naming known. • Passwords: WiFi passwords and default WPS Keys (password testing). • Channels: WiFi channel scanner and WiFi networks through channels in 2.4Ghz and 5Ghz. • Security: Network authentication and security details for WEP, WPA, WPA2 and Enterprise (802.1X) WiFi networks. • Hardware: No special hardware is required for its operation. ![]() Download your Acrylic WiFi free copy, the most advanced WLAN scanner: Acrylic WiFi Home is an wlan analysis software for personal usage.

When performing a, it is important to identify hidden network names, also known as under the 802.11 standard. Before connecting, or even attempting to connect to a wireless network, its name must be known. Furthermore, in case of WPA/WPA2 security type networks, an ESSID is required to verify the Pre-Shared Key (PSK), the encryption key. Usually, WiFi network access points send their network name as one of the Information Elements that are included in some of the management type frames, more precisely, the beacons (type=0x00, subtype=0x05) with the information element which identifier is 0. This parameter structure is shown as follows: For some years, the main manufacturers of WiFi devices operating on AP mode have been giving the option to configure the devices to hide their network names. This has been implemented as a security feature to prevent unwanted connections, since the network name is one of the required parameters to establish connection, although it has an important design flaw. How to Obtain Hidden WiFi Network Name (ESSID) Length Even when a network name is not provided, most devices operating on AP mode send the Information Element that includes the network name as a field containing a hexadecimal 0x00 value, as well as its length. This piece of information is a first approximation to obtaining the hidden WiFi network name. This is also frequent in corporate environments, where network names are usually self-explanatory or follow a certain deducible pattern, therefore it is possible to predict all network names from one of them by knowing their length. How to Obtain a Hidden WiFi Network Name (ESSID) A client device trying to connect to a WiFi network sends a Probe Request type frame to the AP and requests certain information from the AP while sending client device information to the AP.
