iPhone 6s on iOS 11 unable to join wifi network

I updated my iPhone 6s to iOS 11 and I can no longer join my WiFi network. I know the password is correct and my modem/router are working properly as I am able to connect on my work iPhone without problem. Same with a few friends I had over.


What I’ve tried:

- soft reset

- forget network and rejoin

- reset network settings

- disabled WiFi networking services

- toggled WiFi assist

- setting custom DNS


I would like to avoid a hard reset and restoring form a backup at any cost as I’ve run into a ton of issues with doing so in the past resulting in losing everything. Any other troubleshooting ideas?
