how to reduce the length of widi connect time

Hi:

     My PC/win10 is work on GC(wifi-direct group client) mode, My widi Sinker is work on GO mode;

     we calc the connect time is about 10 second from click widi to sink received the media stream;

     the divid time is:

     p2p connect : 2s

     dhcp(GO/sinker wait dhcp request from win10) : 3s

     create tcp connect(GO/sinker wait syn/ack from win10): 3s

     rtsp & hdcp : 1.5s

     so the most time is consume at wait from PC/win10

     is there any way to speed up the dhcp request send from  win10

     or speed up the tcp connect ?

     thank you very much

My notebook is Lenovo ideapad 300s,  which is support source of miracast and widi  and it can miracast to some "chromecast"
