Hi I am new to Ubuntu and Linux. As I am developing a WiFi product, I want to capture the WiFi traffic wirelessly with Wireshark. Having some searching in the web, I know that I can do that with a USB WiFi adapter and Ubuntu. Then I can run the Wireshark in real monitor/promiscuous mode.
Ok so I bought a TP-Link TP-WN722NC (I want to buy the TP-WN722N at first, but the store only has this model). Also I found a laptop and installed the Ubuntu 14.04.1. Then I noticed that I need a driver for this adaptor. So I try to follow the blog post Installing TL-WN722N on Ubuntu 11.10 to install the driver ath9k_htc but seems it was not successful.
Then I downloaded the backports 3.16-1 by running these two commands:
wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.16/backports-3.16-1.tar.gz tar xvf compat-wireless-126.96.36.199-2.tar.bz2
However, after that point do not know what should I do. Could you help guide me to install the correct driver?
