LG G3 Vigor: wifi wont turn on

hi i could use some help in solving my wifi problem please.

k it wont turn on i press the button to turn it on and it slids over and turns blueish green like its supposed to, i have also done this inall the screens that u can to see if it would make a difference and it just goes back to off when ever i exit the page.also when i turn it on, on the page that u search for avalable devices nothing happens its like the button is for show and does nothing..... i would really like some help considering i just got the phone 5 days ago and have been having this problem since the first minute of owning it...
