I have an iMac with OS X Mavericks (10.9) installed. I've been using the Internet Sharing feature to connect to other devices regularly, but since last week the Internet Sharing option has stopped working properly and I can't connect other devices (laptop, smartphones, consoles, etc).
Wi-Fi interface
Wi-Fi TCP/IP settings
I have everything set accordingly. The Wi-Fi is enabled and recognized in my devices but I can't seem to access the internet through them. It has a self assigned IP address and it's not able to connect to the internet. How can this be fixed?
