Hi NaymathKhan,
Could you see the the wireless projector within your network?
If not, then please check to see if you turned on Network Discovery:
Under
Settings-> Network And Internet->WIFI, click your WIFI name, turn on Make this PC discoverable;
Then under Settings->Devices, check to see if you could find the wireless projector, if yes, try to connect it.
Regarding the connecting issue, you may contact the manufacuter and see if they could offer any further assistance.
