How to connect new 5G Sagemcom Fast 5866T modem to Google Nest wifi?

Level 2
Hey there tech savvy people!
We just got an upgrade to 5G NBN with the brand new Sagemcom Fast 5866T modem. It's up and running but I'm not sure how to connect it to our Google Home nest wifi extender.
Our tv is mounted in our converted garage which is seperated to the rest of the house through a brick wall so we managed to get internet out there to our Sony TV through using a Google nest set up, so we need this to connect to the new modem. Otherwise the tv is useless for streaming.
Please let me know what I can do to connect the my google nest wifi extender or what alternative solutions can be employed to get the wifi to work.

Hi @Jaminjam . The Google Nest is configured by phone app, so there's no user guide to read.

The Fast has to run in normal mode; it can't be put into bridge mode.

The Nest might have an operation mode called Access Point. Connect the Nest WAN port to a Fast LAN port.

If the Nest doesn't have that setting, give it another local ip address (eg. and disable DHCP. Connect Nest WAN to Fast LAN. If that doesn't work, connect LAN to LAN.
