Antennas can be 2, 4 or even more, but very important for these 2.4/5.0 GHz chipsets is also MIMO, which, when using multiple antennas, increases the chance of capturing a handshake and is also crucial for achieving maximum transmission speeds data under normal use.īut, unfortunately, Chinese manufacturers often multiplex antennas instead of MIMO or simply place non-connected antennas.
Some manufacturers, for example, Alfa AWUS036ACH, Alfa AWUS1900, TRENDnet TEW-809UB, use additional chips (for example, signal amplifiers) and may have other nice features.įor those who decide to save money and buy products on sites like AliExpress on the above-mentioned chipsets.
This also needs to be considered when purchasing devices. Also, some devices work only in one range of choice, others – in two ranges simultaneously. In some cases, depending on the circuit design of the device manufacturer or firmware, one antenna can be used only for transmission, and the other only for reception.
If you purchased a dual-band (2.4GHz & 5.0GHz) adapter, you need to install the rtl8812au driver, to do this please follow this tutorial: how to Install rtl8812au Drivers on Kali Linux See the article “ How to determine which WiFi adapter is suitable for Kali Linux ” for details. In addition to the monitor mode and wireless injections, in some attacks, the WiFi adapter also requires AP mode and support for virtual wireless interfaces. With any of these models, you can grab a handshake and perform most of the wireless attacks. Here is a large list of monitor mode wifi adapter and wireless adapter capable of injection. Wrong: at least Alfa AWUS036NHA (chipset: Atheros AR9271) can catch PMKID (for attacks on Access Points without clients, Learn about these attacks here). The Realtek chipset has problems (solved) when attacking WPS, and the Atheros chipset seems to be incapable of capturing PMKID. So, if you want to be able to use it to wifi audit and do all the cool stuff that we can do in kali Linux with aircrack-ng and other tools you need to get a kali Linux usb wifi adapter.ĭepending on the selected chipset, there may be nuances. So even if you install kali Linux as a main machine and then you’ll have access to your built-in wireless card but still you won’t to be able to use this wireless adapter for hacking because it doesn’t support monitor mode or packet injection.
