Internet Sharing Not Working

Hello community I have recently ran into a problem with internet sharing. I am trying to share internet from ethernet to WIFI so other devices can connect.

When I turn on internet sharing no wifi network is made and I even double check on devices to see if they can see the wireless network and none is made. Also the WIFI icon at top when internet sharing is turned on is suppose to turn to a upside down triangular shape icon but mine does nothing. I have tried messing with setting such as turned encryption off and on as well as changing the SSID of the network to be made and nothing seems to work. If someone could figure this out it would be extremely helpful as I have friends here that really want to get online.



Thank you.
