Why will my LG G3 connect to other wifi's but not my own?

[AC Question]

LG G3 will connect to other wifi but not my own.

My lg g3 suddenly won't connect to home wifi. It will connect to other wifi and other people can connect to mine. My friend has the same phone and his won't connect to my wifi either. So far I've tried replacing the router , forget and add network, and factory reset. Nothing works.

Try setting the router to use AES, not TKIP or TKIP+AES. (Some of the better routers, like Linksys, won't even work that way. I ended up buying a cheap Netgear WNR2000 [$40] and everything works if it's set to AES.)
