How to Disconnect a Wireless Adapter in Linux
- 1). Log in to the Linux computer as user "root." Launch a command shell, either by logging in in text mode or by launching a Terminal window from the graphical interface. Linux will present you with a text prompt.
- 2). Type the following command into the shell:
iwconfig
Press "Enter." Search for the interface name Linux assigned to the adapter you want to remove. The interface name will appear at the beginning of a line that also lists the name of the wireless network under the "ESSID:" heading. - 3). Type the following command into the shell:
ifconfig wlan0 down
Replace "wlan0" with the interface name you obtained in Step 2. ifconfig will delete the interface from the networking stack and stop using the wireless adapter's hardware. - 4). Physically disconnect the adapter from the computer.
