[edit] How to install Ubuntu 11.10 onto your Pandaboard and get maximum performance
This tutorial http://www.novemberkiloecho.com/?p=82 is for you if you own one PandaBoard and are unimpressed by the speed at which this little devil can perform, this tutorial may help you get the most out of your board using just the SD card. This is just the first step to getting optimal performance. You will see the best performance once you move your OS to an external (preferably SSD) drive. This tutorial will prepare you for that.

- Step by step instruction:
#general system info cat /etc/lsb_release uname -arv #update and upgrade first! sudo apt-get update sudo apt-get upgrade #so we can use iwconfig, iwlist, etc sudo apt-get install wireless-tools #check available wireless cards iwconfig #get wireless security details from wifi router #read explaination from [http://ubuntuforums.org/showthread.php?t=202834] #HOWTO: Wireless Security - WPA1, WPA2, LEAP, etc. #install wpasupplicant software sudo apt-get install wpasupplicant # generate hex hey with ssid and passphrase wpa_passphrase <ssid> <passphrase> # wpa_passphrase# copy the psk and paste it next to wpa-psk
- create a file call interfaces_wlan0 in notepad and then enter the appropriate network configuration. The file should contain settings similar to the following:
auto lo iface lo inet loopback auto wlan0 iface wlan0 inet dhcp wpa-driver wext wpa-ssidwpa-ap-scan 1 wpa-proto WPA wpa-pairwise TKIP wpa-group TKIP wpa-key-mgmt WPA-PSK wpa-psk
- copy all of the above content
#create new file using vi in terminal vi interfaces_wlan0 #hit i for insert and then right click to paste #ESC:x to save # overwrite the old interfaces file with eth0 configuration # create a backup if need to before overwrite sudo cp interfaces_wlan0 /etc/network/interfaces #turn off eth0 before restarting with new wifi configeration sudo ip link set eth0 down #restart networking sudo /etc/init.d/networking restart #check wifi status iwconfig #test ping #if doesn't work need to reboot #security option sudo chmod o=-r /etc/network/interfaces
