Disclaimer I am not in Oz right now and have signed up to an unlimited mobile internet plan on a network that supposedly support 600mbps.
I am currently using a Note 3 LTE cat4 as the hotspot for home internet. So I am now in search of some decent upgrade to a proper 4g modem and maybe router.
To my surprise, most of them are only cat4, cat6 and beyond are few and far between, restricted to a couple of more expensive netgears and huaweis.
So what gives? We already have plenty of cat12, cat16 phones around, so why not modems.
Look into the netgear 810s and NETGEAR Nighthawk® M1
