why my lg g3 wifi isn't working?

[AC Question]

I have my lg g3 for more then one year. I updated it to marshmallow and everything was perfect . Yesterday i saw that my wifi is connected but i can't use Internet. I tried to reboot it, factory reset more then 5 times but nothing works for me !

Try rebooting your router

Try forgetting the connection and trying again. Also, boot into safe mode and see if that works. If it does an installed app is causing problems
