香港寬頻屬於邊隻上網方式

I believe HKBN is using Fibre Optics.
Cartainly not T1/T3/adsl/isdl.

You can select "lan"

Sorry I am not sure what types of software you refer to.
Most of the time, it does not matter if you choose wrongly the connectivity with your software.
Sometimes software vendor ask it for survey only.

Hope it helps!
