Hey sorry for the latest reply ever. I still have these concerns and also slightly in Valorant too.
The XR1000 is connected directly to the NBN FTTP connection box (ONT).
There is no modem/router between the two.
The ONT simply converts fibre to Ethernet and does not perform routing.
The XR1000 is connected to UNI-D1 on the ONT and is handling all routing, NAT, DHCP, firewall, and Wi-Fi functions.
All devices are connected directly to the XR1000 (either via Ethernet or Wi-Fi).
I hadn't realised until today, back in September '25, NBN had rolled out a free speed upgrade to high tier plans, so mine went from 1000d/50u -> 1000d/100u. Today I then adjusted the upload speed accordingly thru Advanced -> Network Speeds.
I generally don't mess around with Congestion Control (still on the default both 100%/off). I'm aware that's probably the main thing that im going to need to do but prior to this i've just never seen much fix.. perhaps due to poor trial and error to be fair. Same goes generally with Bandwidth Allocation, that's kept at default as of now. As for Traffic Prioritization I currently have it off. For whatever reason it doesnt seem to prioritise my packets when set to only my device and Valorant and I'd rather not prioritise all gaming consoles as we have my PC and two PS5s usually running most afternoons.
As for Geo-Filter, I mainly play Valorant but even on COD aswell I only ever play on my own servers. Never found much use for Geo-Filter due to this.
