Hi @cashwood,
Welcome to the Community!
The most possible way in checking which line can provide you with the best line speed is to connect the modem physically to the socket(s) while logged in to your modem's interface or we can also check it remotely but we would still require you to connect the modem to the socket(s).
We also still need to check what type of NBN service will be available in your area as they have different types of technology.
Could you please provide us with your Customer ID via private message so we can check all these for you?
Regards,
Ahra_G
