Personal Router WAN settings question.

New to Brightspeed (and Fiber). Just a quick question. I have an ASUS BE3000 WiFi7 Mesh Router.

I have an iPhone 16 Pro Max and when I dk a WiFi speed test, it seems like it caps out at about half (1200 download).

My default WAN is set to Automatic IP. I’m not sure if it’s best to left it there or change it to “Static IP” or “PPPoE”.

Any thoughts/suggestions and if I do need to change it, how should the setting be configured?

Also, does IPTV need to be set up or enabled?

Thanks!
