Hi @xyloidhead, thanks for providing your address via PM.
I can confirm that your address is TPG NBN HFC serviceable and the modem that we currently supply for this service is TP Link VR 1600v.
1. The modem/router can support up to 30 device.
2. The DHCP option is partially configurable. The modem's firmware is customized.
3. It is AC Dual Band; the range depends on many factors like interference of other devices and environment and cannot be described just by one number.
Theoretically WiFi routers operating on the 2.4 GHz band reach up to 46 m inside and 92 m outside. The range on 5 GHz (Faster Data Rates) band reached probably 30% of the 2.4GHZ distance.
