Designed primarily for those of us who have a cable or fibre internet connection the Asus RT-AC68U router must be used with a separate modem. It isn't a replacement for the `traditional' modem/router units that are found with most broadband connections and that appears to have been the cause of some of the negative comments I've noted in other reviews of this unit. Luckily I have a fibre connection and have been using this new router in place of my Asus `Black Knight' (RT-N66U) model Asus RT-N66U Dual Band Wireless N900 Gigabit Router
. Since buying one of their laptops a few years ago (and more products since) I have gained a respect for Asus products as they tend to be very well-made so I was keen to see how this new router compared to my old one. However, having read the comments of those other reviewers on this website I must say that I did expect to have some issues with its software. Maybe I've been lucky but so far it all seems to have worked ok for me and I wonder if the software updates issued by Asus have now fixed those problems. I hope so as it's a shame to see such an advanced piece of kit causing such concern amongst users, especially from a manufacturer like Asus.
In my own experience the router has performed well with all of my devices (two smartphones, two tablets, two laptops plus other media devices) and I haven't noted any issues with connectivity or reliability through Wi-Fi or Ethernet. I have not dabbled with the settings on the router so it's pretty standard and seems to be at least as good as my other router. However, the `upgrade' in performance doesn't seem to be particularly noticeable for me so I can't help but suggest that anyone trying to decide between this model and the less expensive RT-N66U chooses that one in view of its more widely acknowledged reliability.
