You don't needed to apply for HGC network it is already included in the mangaement fee.
You have to fill in a form to management office then they will give you a cable. this cable is not normal CAT5 cable. If you us the normal one your telephone will be out of service (short circuit by the CAT5 cable).
There is some discussion about how to move your network to another place by yourself in this web site you have to search.
I hear that you can ask HGC help to move the connection but you have to pay $150.
