Can't see any public WiFi

Question

I cannot see any public WiFi using a USB Wifi adapter (TPLink-WN322G).

I've installed Kali Linux on my computer.

In my other PC and smartphone I can see WiFi connections.

After you connect to one of the public Wifi connections, you need to open browser and put your username and password from voucher.

But in my Kali Linux, I cannot see any SSID.

Answer 1

Since Kali Linux is based on Debian, these instructions (from this page) should help:

1. Add a "non-free" component to /etc/apt/sources.list, for example:

   # Debian 8 "Jessie"
   deb http://httpredir.debian.org/debian/ jessie main contrib non-free
   

2. Update the list of available packages and install the firmware-atheros package:

   # apt-get update && apt-get install firmware-atheros
   

3. Connect the device to your system. The ath9k_htc kernel module is automatically loaded for supported devices.

4. Configure your wireless interface as appropriate.

If the above does not help, using another USB WiFi interface might be a solution.
