Well, belive it or not it is your choice ok ? i wont responsible for your failure so with out further it do heres how do I fix the problem and abit explaination about this problem:
My LG Optimus LTE 2 have similar problem, and i fixed it myself after disassembled everything and i noticed that my atenna and the whole phone is abit dusty and after i cleaned it, it work for a while but it is back but i did an atenna replacement and some wireless-signal-related also do a fresh install of the rom and it work like a charm. so my case it is because of the atenna does not gets enough signal for it to be visibal on your software. If my methods i tried didnt work you can either try Evil Monkey's method or use a wifi signal scanner to move your router's channel to a peaceful one and it may work. And do not do my methods if your device isnt out of warranty and get a replacement or have it fix for free by the store you bought the phone
hope it works
