Have you re-entered your Wi-Fi SDID and password?

Edit: I just updated my S6 edge a few minutes ago, and it automatically reconnected to my Wi-Fi after the update.

I too just updated the S6 edge.... it automatically reconnected to wifi without problems after the long install and reboot.

The s6 update wipes your connection settings such as wifi passwords. So re entering the password like everyone here suggested should fix it 🙂
