@David-TP Thank you for your quick response. Well after following your instructions regarding the NBN and Router restart now everything it's working well. I have successfully connected other Deco's....

@David-TP I have followed your instructions to the letter. But it's still not working. Internet is connected and working fine. Only the Decos are not. Please help. Thank you

@Decoish I got the same issue. However, even after the Mac address change its still not working. I don't know if I'm doing it wrong but after installing the new update today it's not working at all....
