So am building a house in an area that has UFB. But because it's a new build (and because I can source some materials cheaply), I am wiring up with Cat6a and have Gigabit devices (NAS, network cards in my main pc and media PC and a LinkSys WRT1900AC router with Gigabit ports).
Was a bit surprised that Spark only offer the Huawei HG630B for home users, which has only 100 Megabit LAN ports. They have another modem (in the Huawei HG659B) which has Gigabit LAN ports, but (and this is direct from someone on their customer support line), this modem is ONLY available for business users and can not be sold to residential customers.

That totally threw me, as I would have thought that business customers get it for free when signing up to a new deal and given that they were happy to give me the HG630B for free and I was offering to let them keep that and I would PAY for the HG659B, they would jump at the chance to let me give them money. Seems stupid to setup my home network as Gigabit capable only to be constrained by a 100 Megabit port on the modem when accessing internet traffic.

Because I can't find the Huawei HG659B for sale online and because Spark won't let me purchase it from them, does anyone know of a decent modem that will connect to the fiber network, has a telepermit approval and has Gigabit ports (don't care about 802.11ac wireless as my router can handle that. I just want a modem with at least one Gigabit LAN port that my router can plug into)?
