How do I connect to a hidden SSID in Windows 10 programmatically?

To connect to a hidden Wi-Fi network (SSID) programmatically in Windows 10, you can use the Windows Native Wi-Fi API. This involves using C++ code to create a Wi-Fi profile with the hidden SSID and then connect to it. Here's a step-by-step guide on how to do this:
- Include the necessary headers:
cpp#include <Windows.h>
#include <wlanapi.h>
#include <wtypes.h>
#include <objbase.h>
#include <wlanapi.h>
#include <wlancli.h>
#include <wlanui.h>
#pragma comment(lib, "wlanapi.lib")
- Define a function to connect to the hidden Wi-Fi network:
cppHRESULT ConnectToHiddenNetwork(LPCWSTR ssid, LPCWSTR key)
{
HRESULT hr = S_OK;
HANDLE hClient = NULL;
DWORD dwMaxClient = 2;
DWORD dwCurVersion = 0;
DWORD dwResult = 0;
// Open a handle to the Wi-Fi interface
hr = WlanOpenHandle(dwMaxClient, NULL, &dwCurVersion, &hClient);
if (FAILED(hr))
{
return hr;
}
WLAN_AVAILABLE_NETWORK_LIST* pBssList = NULL;
// Get the list of available Wi-Fi networks
hr = WlanGetAvailableNetworkList(hClient, NULL, 0, NULL, &pBssList);
if (FAILED(hr))
{
WlanCloseHandle(hClient, NULL);
return hr;
}
// Find the hidden network in the list
bool found = false;
for (DWORD i = 0; i < pBssList->dwNumberOfItems; i++)
{
WLAN_AVAILABLE_NETWORK* pNetwork = &pBssList->Network[i];
if (wcscmp(pNetwork->dot11Ssid.ucSSID, ssid) == 0)
{
found = true;
break;
}
}
// If the hidden network is not found, return an error
if (!found)
{
WlanFreeMemory(pBssList);
WlanCloseHandle(hClient, NULL);
return E_FAIL;
}
// Create a new Wi-Fi profile for the hidden network
WLAN_PROFILE_PARAMETERS profileParams;
ZeroMemory(&profileParams, sizeof(profileParams));
profileParams.dwFlags = WLAN_PROFILE_USER;
profileParams.strProfileXML = L"<WLANProfile xmlns=\"http://www.microsoft.com/networking/WLAN/profile/v1\"><name>HiddenNetwork</name><SSIDConfig><SSID><hex>" + std::wstring(ssid) + L"</hex><name>" + std::wstring(ssid) + L"</name></SSID><nonBroadcast>true</nonBroadcast></SSIDConfig></WLANProfile>";
hr = WlanSetProfile(hClient, NULL, &profileParams, NULL);
if (FAILED(hr))
{
WlanFreeMemory(pBssList);
WlanCloseHandle(hClient, NULL);
return hr;
}
// Connect to the hidden network
WLAN_CONNECTION_PARAMETERS connParams;
ZeroMemory(&connParams, sizeof(connParams));
connParams.wlanConnectionMode = wlan_connection_mode_profile;
connParams.strProfile = L"HiddenNetwork";
connParams.pDot11Ssid = NULL;
connParams.pDesiredBssidList = NULL;
connParams.dot11BssType = dot11_BSS_type_infrastructure;
connParams.dwFlags = 0;
hr = WlanConnect(hClient, NULL, &connParams, NULL);
if (FAILED(hr))
{
WlanDeleteProfile(hClient, NULL, L"HiddenNetwork");
WlanFreeMemory(pBssList);
WlanCloseHandle(hClient, NULL);
return hr;
}
// Clean up and close the Wi-Fi handle
WlanFreeMemory(pBssList);
WlanCloseHandle(hClient, NULL);
return S_OK;
}
- Call the function to connect to the hidden network:
cppint main()
{
// Replace these with your hidden SSID and password
LPCWSTR hiddenSsid = L"Your_Hidden_SSID";
LPCWSTR password = L"Your_WiFi_Password";
HRESULT hr = CoInitializeEx(NULL, COINIT_MULTITHREADED);
if (FAILED(hr))
{
return hr;
}
hr = ConnectToHiddenNetwork(hiddenSsid, password);
if (FAILED(hr))
{
// Handle the error
std::wcout << L"Failed to connect to the hidden network." << std::endl;
CoUninitialize();
return hr;
}
std::wcout << L"Connected to the hidden network!" << std::endl;
CoUninitialize();
return 0;
}
Note: Make sure to replace "Your_Hidden_SSID" and "Your
