Alfa Network AWUS036ACH Review of the best powerful USB WiFi adapter.
ALFA AWUS036ACH is an 867Mbps Wi-Fi USB adapter compatible with Windows XP, Vista, Windows 7/8 and Windows 10. It has two RP-SMA antenna ports with two 5 dBi dual band antennas. The antennas are removable and can be updated. It also has a power amplifier that increases its reception range compared to the previous model of ALFA AWUS036AC.
In our “Review AWUSO36ACH” we have been able to verify that currently the WiFi Adapter AWUS036ACH USB 3.0 AC1200 is the best powerful WiFi adapter “in the world” designed by Alfa Network for indoor use.
The Taiwanese manufacturer Alfa Network is considered the most innovative designer in the world in terms of adapters and powerful Wi-Fi cards. For years this brand Alfa Nertwork Inc. with the logo of the pen and the letters TW (Taiwan) has dominated the market for WiFi USB receivers with G and N technology.
By incorporating the most popular chips in their high-power Wi-Fi cards, the Realtek RTL8187L and the Ralink RT3070 have given satisfaction to all users seeking high performance WiFi cards. When the WiFi dual-band AC has been implemented in the market, Alfa Network brand wanted to continue maintaining a high level and has achieved this thanks to the AWUS036ACH adapter that follows the AWUS036 series of its predecessors the AWUS036H and the AWUS036ANEH
With this new model Alfa maintains the dominant position by manufacturing the best powerful WiFi antennas in the world at a reasonable price for its quality. The good ratings and reviews of the users and of all the fans to take the WiFi even further prove it.
The great power and discharge capacity of this USB 3.0 WiFi adapter is achieved thanks to the new Realtek RTL8812AU chip. This advanced chip allows connections in the AC standard with two 2T2R synchronized antennas allowing maximum transmission speeds of 867Mbps. As claimed by the manufacturer Realtek this chip is designed for use in drones because it allows fast connections over long distances and free of interference.
The compatibility of this AC system is retroactive and also allows to connect to all classic WiFi networks b / g / n, this means that it can be connected to any old or modern router, both at 2.4Ghz and 5Ghz.
This is the description that the manufacturer makes on their official website. RTL8812AU 802.11ac / a b g n USB WLAN Network Controller:
The Realtek RTL8812AU-CG chip is a highly integrated single chip that supports 802.11ac 2-way solutions with a wireless LAN (WLAN) USB interface driver. It combines a WLAN MAC, a WLAN baseband compatible with 2T2R and RF on a single chip. The RTL8812AU-CG provides a complete solution for a high performance integrated wireless device.
802.11ac / abgn
Host interface: USB 3.0 for WLAN driver
Applications: The product is applicable for use in Drones
The AWUSO36ACH adapter comes with two antenna inputs with female RP-SMA type threaded connector to be able to couple external antennas or more range if necessary. In the basic package comes two antennas of omnidirectional type, double band dipole of 5dBi.
The interface of connection is USB 3.0, also it is compatible with connections of USB 2.0 but in this case it will not reach the maximum speed but it will be limited to 450Mbps maximum. The end of the cable that connects to the WiFi card is Micro-B type.

AWUS036ACH USB WiFI receiver with Bluetooth anti-interference system
A novelty is the bluetooth anti-interference system.
It is well known that Bluetooth devices that are located near a WiFi adapter produce interference that decreases the speed of WiFi. The Bluetooth network transmits data through low-power radio waves between 2.402 GHz and 2.480 GHz. Therefore Bluetooth and 2.4Ghz interfere directly. The new WiFi AC of the ALFA AWUS036ACH when using the frequency of 5Ghz is less interfered by the Bluetooth frequency. In addition, the implementation to achieve low noise in the emission completely avoids the problems of this WiFi card with other Bluetooh devices.
To give a new style to the AWUS036 WiFi AC series, the Alfa Network brand has introduced a new design. The V-vents on the top perform an aesthetic and practical function at the same time, since a high-power WiFi adapter requires good ventilation. This ventilation gives you a new and angular line very different from the classic WiFi g / n cards.
In the different sensitivity tests, it has surpassed its rivals both in the frequency of 2.4 GHz and in 5 GHz.
* Improvement in 2.4 Ghz. WiFi N (up to 300Mbps)
Despite being focused on the AC protocol, the AWUS036ACH has excellent performance at 2.4Ghz frequencies and surpasses the b / g / n adapters we know. The Realtek RTL8812AU chip AWUS036ACH outperforms other powerful chips such as the Ralink RT3572 or the Atheros AR9271 working on the 2.4 Ghz frequency. In the same conditions the ALFA AWUS036ACH having more sensitivity gets more stability in the connection and more range. In good conditions you can achieve a real download speed of more than 200MB.
* Upgrade in 5Ghz WiFI AC. (up to 867 Mbps) In different tests far exceeds 300Mbps transmission. It must be remembered that these speeds can only be obtained with fiber optic lines and dual band routers that are capable of reaching these limits.
By capacity, sensitivity and stability the new Alfa AWUS036ACH is the new reference for the powerful WiFi adapters. The connection via USB 3.0 interface allows the maximum connection speed and the RTL8812AU chip makes it stable even at long distance. The implementation of ALFA to eliminate the noise in the WiFi emission has also achieved The new WiFi AC of the ALFA AWUS036ACH 5Ghz completely avoid interference with other Bluetooh devices.
AWUS036ACH 5Ghz is capable of receiving and transmitting in the 2.4 GHz and 5 GHz bands. Working with the new standard 802.11ac router, the AWUS036ACH can achieve transfer speeds of up to 867 Mbps, almost three times that of the maximum 802.11n of 300 Mbps.
The high reception sensitivity together with the internal power amplifier also allow you to pick up Wi-Fi signals up to 3 times the distance of the new internal 802.11ac Wi-Fi cards that are shipped within current laptops.
The RTL8812AU chip works with any computer that has a USB 2.0 or 3.0 port. The drivers are available with all Windows including Windows 8 / 8.1 or Windows 10.
To achieve maximum speed requires a computer with USB 3.0 port and a dual band AC router.
