WiFi doesn't work when SuperSU 2.72 binaries are installed on Android 7 Since a few days I have Cyanogenmod 14 for my Samsung SM-G900f. I want to use some apps by Chainfire but they all require his su binaries so I tried to install it via the SuperSU app, which always fails, and via TWRP, which then worked.
After flashing it I noticed that I when I turn on WiFi that it just scans but nothing appears; even the already saved networks won't show up. I also tried connecting via WPS pin and WPS push, but it just gives me an error message.

Does somebody have any idea what the cause might be?
Today, SuperSu released a new version with a wifi fix https://download.chainfire.eu/1014/SuperSU/SR5-SuperSU-v2.78-SR5-20161130091551.zip
