How can I adjust the preferred WiFi order? [duplicate]

I am using 13.04 Ubuntu. I want to make order on multiple wireless access.

Is there any way to do this?

You may find this blog helpful about an app called wifi radar that can create profiles for networks.

WiFi Radar is a Python/PyGTK2 utility for managing WiFi profiles.It enables you to scan for available networks and create profiles for your preferred networks. At boot time, running WiFi Radar will automatically scan for an available preferred network and connect to it. You can drag and drop your preferred networks to arrange the profile priority.

You will require your root password to use the program. Once opened it should detect any available networks. You should then be able to drag and drop your preferred networks to arrange the profile priority as you wish.

You can download through the Ubuntu software centre or at this website. Another option to install is to open a terminal and type sudo apt-get install wifi-radar
