## Updated 9 Jul 2009 to match hte wpa.html file.
## Script for running wpa_supplicant daemon,
## after installing previously set up files to connect to
## bham wireless network.
## This script ends with two steps
##    1. it invokes wpa_cli reassociate
##    2. it runs wpa_cli in interactive mode
## Step 2 can be replaced by running wpa_gui (graphical interface)
## if you have that. (See comment at end of file)
## It will provide a graphical tool, which some users may prefer.
## It also allows you to omit user name and password from the
## file /etc/wpa_supplicant/wpa_supplicant.conf
## If you leave them out then wpa_gui can ask you to type them
## into windows that it will pop up. That may be more secure than
## leaving them in a file in a laptop computer that might be lost or
## stolen
##
## NB before running this script you should have saved the files that
## it overwrites as explained in
## http://www.cs.bham.ac.uk/~axs/laptop/wpa/
