WiFi Alpha Adapter Review

WiFi Adapter is a device used as an additional backup wifi interface. It is also used for assessing wifi security and to pentest wifi systems. When selecting wifi adapter, the selection of a chipset is extremely important. It will help in identifying frequencies that the adapter will support.

Remember, older wifi devices used 2.4 GHz while newer wifi devices used 5 GHz. Hence while selecting adapters, It is essential to find whether the device support 2.4 GHz or 5 GHz or both frequencies.

I have recently used the Alfa AWUS036ACH adapter to hone my skills in wifi security. Below is the list of security features that I have found while using the Alpha adapter:

• 300 Mbps
• USB 3.0 wifi adapter
• Support both Linux, Mac, and Windows operating systems
• 802.11 Wireless sniffing
• Able to capture wifi frequency of 2.4/5GHz using airmon-ng (aircrack-ng suite)
• Support for monitor and packet injection mode
• Support Penetration Testing frameworks like Kali Linux (after some minor configuration changes) and Parrot
• Difficult to install on Windows 11 although you can easily install it on older Windows OS
• Supported standards include 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac

Specifications of Supported Standard

Protocol	Frequency (GHz)	Approximate Range (m)
802.11a	5	35
802.11b	2.4	35
802.11g	2.4	38
802.11n	2.4/5	70
802.11ac	5	35
