How can i turn the sound off for wifi available notifications only, on an s7 edge?

[Android Central Question]

I work at an airort and go between terminals alot which always dissconects me from the wifi. If my phone isnt on vibrate i will hear the same notification sound as the one i have for texts. Is there a way to specifically set it so that i can turn the sound off for that notification? Ive looked around and people were curious about this for other apps but seeing as the wifi isnt an app i dont seem to be able to find an option for it.
