    thats great, but id only buy this for laptops, and id need a ton of those USB dongles which make the laptop very bulky IMO.

    “Can’t get full speed out of the device with current technology.”

    I don’t see how this is a Con? You say it’s future proofed as a pro, then say it’s a con at the same time? I’d rather it be ahead of the game so I don’t have to be buying new routers when faster tech comes out.

  • Brian

    I understand the point – its very fast, but its hard to get full speeds. None of my laptops can handle this speed, due to the current technology. so its good to look ahead but right now you are limited.

    Good review actually, im buying one as I might pick up a few of those USB netgear dongles too.

    Kitguru is an excellent website but the author of this article seems to have some difficulty with consistent units of measurement. There is quite a difference between MB/s (megabytes per second) and Mb/s or Mbps (megabits per second). 450 MB/s is about 3600 Mbps (SSD data transfer speeds) and is unlikely to be seen on a current wireless router.

  • Hi Idawari, That was actually my fault as I meant to edit the 2 or 3 ‘MB/s’ errors to the correct naming.
