This is the beauty of the NBN, surely. A single provider of the underlying infrastructure and many, many choices as to your biller/modem provider. In the past with cable you were lucky to have a choice between Telstra and Optus, often it was one or the other.
Now with NBN go wherever you want, whenever you want. Unless of course you sign up for a long term contract in order to get a free/cheap modem and then to be honest that's your choice, nobody made you do it!
so I have to enable bridge mode on the Sagemcom 5366tn but I can't find any details on how to do it?
It does not have a bridge mode.
Only FTTN & FTTB require a router with a modem. What type of NBN do you have?
I have a FTTN Nbn
In that case the only things you can play with are disabling NAT & DHCP and/or putting your gaming router in the DMZ. Note that messing with any of those will/may loose:
I read this morning that Optus has added a new "Ultra WiFi" NBN modem to their lineup with 4G backup. Anyone planning to get their 5366TN replaced with this?
"nbn plus an Ultra WiFi Modem with 4G backup."
