Hey,
Ill be connecting to the HFC NBN shortly and keen to get a modem in the 100-250 price band. The house isnt overly big and really the modem will be used for streaming content/netflix etc - no gaming or anything too onerous.
There is so much mumbo jumbo out there and it's hard to nail down exactly what's required for HFC NBN.
Cheers
NBN supply modem for HFC, you plug in your own router.
