How to start a WiFi hotspot in Windows with python?

Question

I want to start a WiFi hotspot in windows 10 and windows 11 with python , so that I can control my device via WiFi and get access to the wired network connected to the device, which has no Internet connection.

I tried to use the cmd command "netsh". However, it can only work when I already have an Internet connection and set the network adapter to "Enable other network user to link via this computer's Internet connection".

Then I tried to use the windows api and the function "WlanHostedNetworkForceStart ", but I am puzzled at it. The following program generated by AI can not work either.

import ctypes

# Load the Windows API library
wlanapi = ctypes.windll.wlanapi

# Define the GUID for the wireless Hosted Network
WLAN_HOSTED_NETWORK_PEER_AUTHENTICATION = 4
WLAN_HOSTED_NETWORK_REASON_SUCCESS = 0

# Define the structure for the wireless Hosted Network
class WLAN_HOSTED_NETWORK_PARAMETERS(ctypes.Structure):
    _fields_ = [
        ("SSID", ctypes.c_wchar * 32),
        ("dot11BssType", ctypes.c_uint),
        ("uNumberOfPeers", ctypes.c_uint),
        ("PeerList", ctypes.POINTER(ctypes.c_void_p)),
        ("dwMaxNumberOfPeers", ctypes.c_uint),
        ("dwAllowedPeerListSize", ctypes.c_uint),
    ]

# Define the function to start the wireless Hosted Network
def start_hosted_network():
    # Initialize the parameters for the wireless Hosted Network
    params = WLAN_HOSTED_NETWORK_PARAMETERS()
    params.SSID = "MyHostedNetwork"
    params.dot11BssType = 1
    params.uNumberOfPeers = 0
    params.PeerList = None
    params.dwMaxNumberOfPeers = 0
    params.dwAllowedPeerListSize = 0

    # Start the wireless Hosted Network
    ret = wlanapi.WlanHostedNetworkForceStart(ctypes.c_void_p(), ctypes.byref(params), None)
    if ret != WLAN_HOSTED_NETWORK_REASON_SUCCESS:
        print("Failed to start the wireless Hosted Network")

# Call the function to start the wireless Hosted Network
start_hosted_network()

What is the right way to deal with the problem?

Otherwise , I found a solution which uses another way.

Use

and run it as a .bat file or run it in cmd .

That looks amazing! How does it work? Perhaps the principle of this method can be use in Python
