Using a raspberry pi for remote-WiFi console access

2013-01-01 23.19.20

Bill of materials:

1 x Raspberry Pi model B rev2 (The latest version with 512 MB RAM, this version doesn’t have any issues with usb wifi dongles)

1 x USB to serial adapter

1 x usb wifi dongle


1.  Download and install the latest raspbian image from official raspberry pi website

2.  Finish the initial configuration

3.  Update repositories for available packages

  • sudo apt-get update

4.  Install minicom

  • apt-get install minicom

5.  Configure minicom

First we have to locate the proper serial device

  • find /dev | grep ttyUSB

Note down the result and proceed with minicom configuration

  • minicom –s -> Serial port setup
  • Change setting A – Serial Device

/dev/modem to /dev/ttyUSB0

(in place of ttyUSB0 enter the device listed from  find /dev | grep ttyUSB)

  • Change setting  E – Bps/Par/Bits

Most common bitrate is 9600

  • When done save configuration

6.  Next we have to setup wireless connection

  • The easy way is to open the window manager with startx command and then open the wpa_gui tool.
  • The hard to way is to edit the wpa_supplicant.conf file

vim /etc/wpa_supplicant.conf

  • Use the below link as reference:

7.  Access raspberry pi with your favourite ssh client



  1. A good practice is to always change the default root and pi user passwords to avoid any security issues.
  2. Insert minicom inthe  last line of ~/.bashrc to have minicom running on startup.
  3. Add a static IP to raspberry pi to be easier to access it.
