NO WIRELESS CONNECTION ASUS X550ca

Hello, so basically from one day to another my wireless connection has stopped working...i can only connect to my wireless by using an ethernet cable..I've tried rebooting my whole computer to factory settings...and it hasnt worked..I don't know what to do.... do any of you have any ideas as to what the problem could be? thank you in advance

Most laptops have either a key combination or dedicated switch that toggles the wireless on and off. I would check to see if maybe you accidentally disable the wireless on your laptop.
