Won't connect to home wi-fi

My iPhone 6s-plus won't connect to home network since 11.2 update. The 'Incorrect Password' prompt continually pops up, when i know for sure it is the correct password. I've restarted router, reset Network Settings, restarted phone with no success. It is only my home network it won't connect to. My other devices at home have no trouble connecting. Also, my phone has no trouble connecting at work. It appears just to be the network at home. Halp!?
