There is a problem with my hotspot

hi everyone, 

 My hotspot can be connected via a mobile phone, but it cannot be connected via a computer. I want to know why. I want to implement the microcontroller as a server and send the information to any device connected to it. How can I do it?

g_provision_info.channel = 11;
nx_system_initialize();

strcpy((char *)&g_provision_info.ssid, "YYK_ap");
strcpy((char *)&g_provision_info.key, "12345678");

/*call the Wi-Fi module provision API*/

return 1;
