With the wireless spectrum starved for bandwidth, the steady move towards the next generation 802.11AC standard couldn’t be coming at a better time. ASUS has been at the forefront of this movement from day one and their new AC68-series (consisting of the RT-AC68U and PCE-AC68) builds upon their previous generation RT-AC66U and PCE-AC66 models but really takes things to the next level.

The easiest way to think of these new AC68 models is that both are ASUS’ ‘tock’ model to their first generation AC66’s ‘tick’. Like Intel’s ‘tock’ models, consumers can technically purchase only one or the other and see improvements in their wireless home networks performance but, in a perfect world, they’re meant to be paired up together for optimal performance.

So what does this perfect scenario consist of? The primary component is ASUS’ $239 flagship RT-AC68U router which takes over from the well-regarded RT-AC66U. The PCE-AC68 meanwhile is a PCI-E based add-in board which retails for $99 and is supposed to bring ultra quick AC wireless compatibility to your desktop system with a minimum of headaches. These two devices are should bring home networking to the next level through their powerful interfaces, versatile installation procedures and user friendly software stacks.

With the progression from the AC66 to AC68 taking less than a year, some may be worried that these new units are nothing more than slight refreshes of their predecessors. That isn’t the case. Because the 802.11AC standard is still only in the Draft stages neither the RT nor PCE promise major improvements in their theoretical performance throughput but there are plenty of updates going on behind the scenes.

Like the previous AC66 models both are rated for 1300Mbits/s but real world component performance has been augmented and some pretty major improvements to the older 802.11N network standard have been incorporated. Instead of combined performance potential of 1750Mbits (or 1300Mbits/s over 802.11AC 5GHz network and 450Mbits/sec over 2.4GHz 802.11N) these two devices are rated for 1300+600. This is how the new ‘AC1900’ rating has come into being and is one of the largest distinctions between the AC66 series and the new AC68.

On its own this rather significant change warrants an entire new model name, but this is only the tip of the iceberg for these new devices. The PCE-AC68 may use the same half height PCI-E x1 form-factor, heatsink and technically the same controller as the previous AC66 but Broadcom has tweaked this version. So, unlike the PCE-AC66, the PCE-AC68 is fully compatible with Haswell based systems.

Ports & interfaces

Connectivity technology The technology that enables connectivity of the device, e.g. wired or wireless.
Host interface Interface that enables a host controller to communicate with a driver.
PCI Express
Interface Interface ports to connect pieces of equipment. USB (Universal Serial Bus) has become the most popular wired interface to connect peripherals. USB 2.0 supports speeds up to 480 Mbit/s (USB 1: 12 Mbit/s). The interface FireWire is also known as the IEEE 1394 standard. Enhanced IDE (EIDE)is sometimes referred to as Fast ATA, Fast IDE or ATA-2.


Maximum data transfer rate The maximum speed with which data can be transmitted from one device to another.
1300 Mbit/s
Networking standards The way in which the network is working, e.g. IEEE 802.11a, IEEE 802.11b, IEEE 802.11g.
IEEE 802.11a,IEEE 802.11ac,IEEE 802.11b,IEEE 802.11g,IEEE 802.11n
Wi-Fi band The frequency bands the product features.
Dual-band (2.4 GHz / 5 GHz)
Frequency range
2.4 - 5 GHz
Modulation Modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal (High Frequency Signal), with a modulating signal which typically contains information to be transmitted. The aim of digital modulation is to transfer a digital bit stream over an analog bandpass channel, for example over the public switched telephone network (where a bandpass filter limits the frequency range to between 300 and 3400 Hz), or over a limited radio frequency band. The aim of analog modulation is to transfer an analog baseband (or lowpass) signal, for example an audio signal or TV signal, over an analog bandpass channel at a different frequency, for example over a limited radio frequency band or a cable TV network channel.
Security algorithms Security algorithms are used to provide authentication, cipher key generation, integrity and radio link privacy to users on mobile networks. The security algorithms supported are the ones that can be used with this product.
