iphone 6 not connecting to Wi-Fi

My iPhone 6 no longer connects to my home Wi-Fi network. My router shows up on the list of available networks but when I try to join it all I get is the spinning circle next to the network name constantly. I've followed all Apple's advice (power cycling router and phone, resetting network settings etc.) but still the same. I can connect to Wi-Fi at work no problem and all my other devices at home can connect without any issues. My only other option is to restore factory settings but i'm hoping i won't need to go that far.
