Only a few WiFi adapters are capable of doing this. Most WiFi attacks require that we are able to inject packets into the AP while, at the same time, capturing packets going over the air.
In the Aircrack-ng suite, we need to be able to use airodump-ng to collect or sniff data packets. That is not what we are willing to settle for. Without this ability, we are limited to using our WiFi adapter to only connect to wireless Access Points (APs) that accept and authenticate us. This enables us to see and manipulate all wireless traffic passing through the air around us. In wireless technology, the equivalent is monitor mode. When we want to sniff a wired connection and pick up all packets going over the wire, we put our wired network card in "promiscuous" mode. Network adapters, whether it is wired or wireless, are designed to only capture and process packets that are sent to them. A good external WiFi adapter is a must have tool for everyone who has interest in the cyber security field. In that case we also need an external WiFi adapter to play with WiFi networks. If we are running Kali Linux on Virtual Machine then also the inbuilt WiFi Adapter doesn’t work for us. It is the WiFi chipset that allows our mobile phone laptop or other devices which allows us to connect to our WiFi network and access the internet or nearby devices.īut most of the Laptops and mobile phones come with inbuilt WiFi chipset so why do we need to connect an external WiFi adapter on our system ? Well the simple answer is our in-built WiFi hardware is not much capable to perform security testing in WiFi networks.Usually inbuilt WiFi adapters are low budget and not made for WiFi hacking, they don’t support monitor mode or packet injection. Why Do We Use External USB WiFi Adapters in Kali Linux?Ī WiFi adapter is a device that can be connected to our system and allows us to communicate with other devices over a wireless network. TP Link N150 TL-WN722N version 1 is notĪvailable in the market right now. Version 2 and 3 has the Realtek RTL8188EUS chipset and requires some modification on it's driver then we can use it. Version 1 comes with Atheros AR9002U chipset and supports monitor mode. TP Link N150 TL-WN722N’s previous versions support monitor mode. For anĮxample, on the Internet lots of old and misleading articles thatĭescribe TP Link N150 TL-WN722N is good for WiFi security testing. We need to choose WiFi Adapter for Kali Linux carefully. RTL8821AU ( require some installations).RealTek RTL8812AU (RTL8812BU & Realtek8811AU doesn’t support monitor mode).Atheros AR9271 (only supports 2.4 GHz).Here are the list of WiFi motherboards supports Monitor mode and Packet injection. The ability to inject packets and capture packets simultaneously.
