I just want to remind you that I'm NOT part of the support team. This is a community forum.

What error are you getting with the last option. I gave you?

On that link try choosing the gamer chat option and then ask to be redirected

Have you tried with this link as well?

Press the Xbox button.
Open Settings.
Go to Network and select Network settings.
Select Advanced settings.
Select Alternate MAC Address.
