想在家無線上網, 應怎樣做? 買wirless router? Wi-fi又相同嗎?

You don't have to apply anything from netvigator. Just buy a wireless router and set it up. That's all.

But then, just wanna remind you that netvigator use the internet type is PPPoE
just need to type in ur login id and password. Everything should be fine.
