SFOS 18.0.0 GA-Build339 Port2 (WAN) Showing as unplugged

Question

Hi, 
 I just did an upgrade from SFOS 17.5.10 MR-10 to SFOS 18.0.0 GA-Build339. 
 
 All went smoothly, rebooted, I'm a happy camper but then I notice that there's no internet connectivity. 
 
 I look under Network Interfaces and see that my PPPoE is showing as unplugged. 
 
 I check all cables and all is fine so I do the old turn it off and back on again IT Crowd trick. I noticed on my hardware upon boot, the link light is on but once booted it goes out. 
 
 So I rolled back to SFOS 17.5.10 MR-10 and everything is perfect again

Has anybody seen this with SFOS 18.0.0 GA-Build339 and knows what the fix is? 
 
 Thanks

Thank you for the pretty pictures.
Why does your v17 network show a 100 and a 1000 connection on the same interface? The WAN interface does not appear to auto negotiate and maybe the driver in v18 is a little more strict with connectivity. Have you restarted your modem. eg powered it off for about minute them on again?

 I have accepted your reply as an answer as it lead me to look at the connection. The long and the short of it is that I don't know why it was showing 100 an 1000 on the same interface, but hard-coding it to 100mb Full had me able to connect to the NBN again. 
 
 So unless Scotty from marketing increases NBN from 100mb to something faster, I should be okay. 
 
 Thanks for the help, now time to tame this V18 beast!
