Download Driver ASUS PCE-AC68 AC1900 PCI-Express. The Wi-Fi ASUS PCE-AC68 AC1900 card, this Wi-Fi card has the peculiarity that its interface is USB 3.0 but PCI-Express. This decision is because it is oriented desktops that want to get high wireless performance. The main features of this Wi-Fi PCI-E card is Wi-Fi connectivity with selectable dual band AC. We can achieve speeds of up to 600Mbps in the 2.4GHz band with its three antennas in MIMO 3T3R configuration using the Three-Stream and TurboQAM technology to achieve this speed. The technology allows using 256QAM TurboQAM frequency modulation 64QAM instead of commonly used in this band. Regarding the 5GHz band, we can achieve speeds up to 1300Mbps thanks to the Wi-Fi technology AC and three antennas 3T3R MIMO configuration. This Wi-Fi card makes use of the main features of Wi-Fi AC as 80MHz channel width, frequency modulation 256QAM and the Beamforming technology for wireless signal focus on customers, thus always get the best possible coverage, ASUS has called this feature AiRadar and promises up to 150% more performance than other computers without this technology. This device is also compatible with 802.11b / g / n networks.
With all these technical features, this PCI-Express card is the ideal companion router ASUS RT-AC68U and ASUS DSL-AC68U, both teams AC1900. A very important detail of this card is that it incorporates a Wi-Fi base where we can connect the antennas, thus, if we have many cables in the back of the computer, it will not be a problem because we can place the antennas at the base, and the base connect via antenna cable to the proper PCI-E card.
Wifi External analysis
The Wi-Fi ASUS PCE-AC68 card comes in a box of blue color with different shades, on the left we see the external base antenna Wi-Fi. In the front of the box are the main characteristics such as Wi-Fi is AC1900 or PCI-E is type. In the bottom right are other features such as speed (1300Mbps + 600Mbps), coverage of up to 150% greater than other teams, the AiRadar technology and also we can use the base antennas to avoid having to directly connect the detachable antennas .
On the right side of the box are the main technical specifications of the card that we have told in the introduction. At the top we see that is compatible with Windows 8 and IPv6. On the back of the box diagrams and graphs are its main features such as TurboQAM technology for 2.4GHz band, the technology for focusing AiRadar where we are connected wireless signal and the installation of the antenna base in instead of connecting the antennas Wi-Fi directly into the PCI-E motherboard. Finally, in this area we find a comparison with other Wi-Fi adapters, let us clear that the performance of this adapter is the best currently.
At the base of antennae, three connectors are type RP-SMA female and connect directly to the PCI-E card that has RP-SMA male connectors. Quite possibly have lower yield per signal loss if we use the base instead of directly connecting the antennas, this is normal as there is always signal loss in the cable. The base antennas also have RP-SMA Male to connect Wi-Fi antennas removable. The Wi-Fi ASUS PCE-AC68 card is red and has a large sink with ASUS logo on the front. In the area where the antennas or antenna cable that leads to the base of antennas are connected, we can see an activity LED will inform us if there is data transfer. At the rear of the plate are all the circuitry and some stickers with the card model, serial number and MAC address.
Wifi Internal Analysis
Once you have seen the Wi-Fi ASUS PCE-AC68 card out, we will remove the heatsink and see its internal components. To remove the heatsink simply unscrew the three screws that secure it to the plate, once removed will see the Wi-Fi controller and a metal plate with a thermal mass on top.
The wireless controller is Wi-Fi card is Broadcom BCM4360KMLG, an old acquaintance and also part of the wireless controller routers ASUS RT-N18U and ASUS DSL-AC68U among many others, which is why the performance is outstanding. The main features of this controller is that Wi-Fi is compatible with standard 802.11ac 3T3R MIMO configuration with the Three-Stream technology to achieve wireless speeds up to 1300Mbps on the 5GHz band. This controller incorporates everything you need to work with the standard 802.11ac as radio, Wi-Fi subsystem and the baseband. The modulation signal is 256-QAM for both bands, so why also use it to get 600Mbps 2.4GHz with Turbo QAM. The Broadcom BCM4360KMLG supports 40MHz channel widths for the 2.4GHz band and 80 MHz for the 5GHz band.
Other features of this chipset using Wi-Fi AC is its Beamforming, LDPC (Low density parity check) and STBC (Space-Time Block Codes), all to increase the transmission efficiency and achieve maximum wireless high speed. The three amplifiers for the 2.4GHz and 5GHz (not simultaneous) are the 5003L1 Skyworks.
When checking if wireless speed and coverage falls short of the best Wi-Fi cards, or on the contrary, is below has arrived. If this is the first time you see one of our analysis, we recommend reading our test bench Wireless. Because this Wi-Fi card TurboQAM incorporates technology to achieve up to 600Mbps in the 2.4GHz band, and also has Wi-Fi AC, we decided to do all the tests with the client-server TCP JPerf and 50 concurrent threads. We have used two routers to check the wireless performance, the ASUS DSL-AC68U with Wi-Fi AC1900 and the ASUS RT-N18U N600 Wi-Fi (Turbo QAM). In the comparison table you can see the Wi-Fi achieved with other Wi-Fi cards we have in our laboratory performance.
This Wi-Fi ASUS PCE-AC68 card has swept completely all our previous records, this is the best Wi-Fi card we've tested so far. We achieved a top speed in the 2.4GHz band of 31.2 MB / s, making a speed of 250 Mbps real, we had never gotten a similar record so far. As for the 5GHz band, has been able to beat the speed record set between two routers D-Link DIR-868L getting up to 66MB / s wireless speed (the previous record was 64MB / s) as we face the best Wi-Fi market and advanced to incorporate compatibility with Turbo QAM card.
ASUS Software for Windows
ASUS offers users the ASUS PCE-AC68 software for managing different wireless networking card. We could use that one with Windows system operator actually own it integrates seamlessly with him, so we will not have any problems. After installing drivers and software like any other Windows program, restarting the PC will see the main screen of the software where we show the Wi-Fi wireless networks around us:
To connect simply tap on our Wi-Fi wireless network and enter the passkey, we may also use the WPS router to connect without entering a password. Once we have connected networks in the store Wi-Fi network is saved and can be accessed from "Settings" to at any time change its settings. As for WPS, we can connect through the introduction of the PIN number or pressing the button on the router and selecting the "WPS button". The software also allows us to check the connection status such as link speed, the signal in dBm, the IP obtained through DHCP and even frames received correctly:
Wireless performance in excellent 2.4GHz band, is also compatible with TurboQAM for greater wireless speed with compatible routers.. Wireless performance in the 5GHz band excellent, we managed to 66MB / s speed Wi-Fi, setting a new speed record. It incorporates a base antenna for easy installation thereof in case you can not do it right on the PC tower.
Wifi Final Conclusions
Most manufacturers have launched routers networking Wi-Fi and Wi-Fi AC1750 AC1900, however, most of them have only launched Wi-Fi cards AC1200 maximum unable to maximize performance wireless routers. However, the manufacturer ASUS itself has, and proof of this is the Wi-Fi card with PCI Express interface for desktop computers. While other brands the only way to take full advantage of the Wi-Fi network is buying two units of its more expensive router in ASUS we acquire the router and the Wi-Fi card you get a huge performance.
We were impressed that achieved in the two frequency bands, both for its wireless coverage as its speed performance test performance. This Wi-Fi card in conjunction with the ASUS DSL-AC68U has exceeded the current speed record that was 64MB / s via Wi-Fi AC. Another strong point is the value of the Wi-Fi card, which can be found in stores at a price of 80 €, a very competitive price when you consider the achieved performance and also incorporates a base antenna to facilitate installation.
The only fault I could put this team is its interface, and is to have a PCI Express interface means having to remove the desktop, locate the PCI Express port and prod the card, something that might not be easy for all users . If ASUS pull out a Wi-Fi card with USB 3.0 interface (albeit larger than normal to incorporate the three antennas), we are confident that devastate sales to take advantage of the Wi-Fi routers double current band.
