No IPv6 on one Mac computer (Solved)
 

All of the computers in my house are Macs and they all get IPv6 addresses except one. All of the computers are on the latest macOS 10.13.4 (High Sierra) but one is older and only supports 10.11.6 (El Capitan). All of the system settings are the same, but the older one is not getting an IPv6 address. All of the searching I have done says that IPv6 is fully supported on every version of macOS since 10.6 (Snow Leopard) and it should be working. I am fairly certain is was working when I upgraded to Internet 50 and this new Actiontec T3200 router. The Actiontec was factory reset a few days ago (which caused a firmware update) and only the wireless settings were changed and some DHCP entries for the devices we have.

Does anyone know why this would be?
