Question

How can I programmatically enable and disable WiFi connectivity with a jailbroken iOS device?

Answer 1

void SetWiFiMode(BOOL mode)
{
    void* manager = WiFiManagerClientCreate(kCFAllocatorDefault, nil);
    if (mode)
    {
        WiFiManagerClientSetProperty(manager, CFSTR("AllowEnable"), kCFBooleanTrue);
    }
    else
    {
        WiFiManagerClientSetProperty(manager, CFSTR("AllowEnable"), kCFBooleanFalse);
    }
    CFRelease(manager);
}

To use this your application entitlements should have com.apple.wifi.manager-access key with boolean value set to true. All functions can be found in private MobileWiFi.framework

There isn't a way using the APIs provided by the SDK. It's trivial to do if you use private frameworks, but if you use private frameworks, you will be in violation of Apple's SDK license agreement.
