Q: internet sharing not working

I'm running a 2008 iMac 2.66 GHz Intel Core 2 Duo with OS 10.11.3.

 

When Apple pushed out that security update that broke everyone's Ethernet port recently, it busted mine too (until I installed the exclusion list update here:

So now the Ethernet port is OK to get online with the iMac, but I can no longer share my internet connection over Wifi. IPhone 6 with current iOS will "see" the network but just spins and spins (never obtains an IP). We used to use it all the time with no problems whatsoever, and with multiple various sorts of devices all at once... But no more.

 

None of the obvious fixes or things I've seen elsewhere in the forum have helped (turn off sharing and restart, screw with DNS settings, etc.). Firewall is not on. PLEASE help.

 

Thanks
