ASUS RT-N66U Dual Band Wireless N900 Gigabit Router Review

Rating: 9.0.

For many of our readers a router is a device that will be provided by an ISP (such as Virgin or BT) but for others it is the central hub of a multimedia environment. Whichever the case is it is an essential part of any modern household. This is especially true since the rapid advances in smartphones and tablets which are requiring ever faster wireless connections.

Some households in the UK are now at the stage where they may have more than ten internet connected devices. I, for instance, have six devices that I use regularly to access the internet, whether it to watch TV, check my email or even write this review. Other homes are likely to have at least three or four devices active at any given time.

It goes without saying that an ever increasing demand is put on a router and as such having the latest model is usually a worthwhile investment.

Today's router up for review, is the ASUS RT-N66U Dual Band Wireless N900 which is capable of transferring up to 900 Mbps across the two bands, this is certainly a large step up from your more humble N300 router that your ISP will supply you with (if you are lucky).

KitGuru Games: An Ode to GAME UK

Today, I wish to look at one company which for many evokes an extreme sense of nostalgia, bittersweetness and formative memories – but for others, is a relic of a dying age. This is an ode to the UK’s most prominent – yet soon to be deceased – retailer of our collective favourite past-time: GAME...


  1. Seriously!!! You really expect me to believe that you tested correctly and received 450mbps in the same room and 405mbps 23 m away! I test computer hardware for a living and am lucky indeed if I can get half of the rated speed of a router even in the same room in ideal conditions. I would like your reviews more if you mentioned exactly how you test the equipment from a software and hardware perspective. I have tested this router and came nowhere near your results and I was using the Asus USB N66 client and Lantest.

  2. I have this router and it holds between 400-450mbps in all of my house – even downstairs through two walls. All depends on the partnering equipment and other signals in the house.

    @greg – I wouldnt be getting so excited about it. I also would look for a new job if you test hardware and get on like this, not good for your blood pressure. Even with a cape and supercharacter logo on it.

  3. I have a netgear router capable of over 500mbit and it holds over 400mbit downstairs and even between a wall. it drops to around 380 outside the house at the rear, which is quite some distance.

    The issue Greg is experiencing is conflicting signals and often neighbouring signals can reduce speeds too. my cousins house has wireless neigbouring systems all around and its not too good.

    Getting good wireless signals is very much to do with partnering gear and a clear signal without others in the path.

  4. if I make my account have a super hero avatar can I act like a twat too?

    ive a rangemax and that helps, but I notice my signal can go up and down a lot at times. sometimes I get 300mbit then other times 380mbit, but yesterday I was getting 180mbit. I need a new setup. I do notice if my wireless source is close to my mobile phone it drops badly !

  5. What options to choose? What are the benefits. Confusing 🙁
