Looking for a Wireless Router - Budget Is < $200

I'm looking for a router to replace the generic Telstra one that was installed last year. It's alright, but range is pretty poor and it isn't meant for someone who wants to alter proxies and dns…

Been looking at the Netgear R6400 but wondering if there might be anything better.

Budget is <$200

Needs to have at least 4 gigabit ethernet ports

I'm currently on Telstra cable, soon to be upgraded to the NBN HFC network - something somewhat future-proof would be ideal

Thanks in advance for any suggestions!! :)
