WPA is not working from the User Interface in Build 650! Some OLPCs (including in the G1G1 program) cannot connect to wireless routers protected with the WPA protocol. Although the networks are visible from the OLPC, they stall when user enters a password.

[Solution: Turn off WPA]

  • If you can turn off WPA from your router, you should be able to connect by choosing the access point from the neighborhood view. This is, by far, the least desirable solution since operating without any encryption is dangerous and WEP is trivially crackable. (Really this shouldn't even be suggested as an option.)

[Solution: Upgrade to Build 653]

Advanced members and General Public (follow general public instructions on link) should consider upgrading, from build 650 to 653 (G1G1 comes with 650 installed), where WPA is working much better (for many more access points). *Netgear access point confirmed working

[Solution: Manual Script]

  • If you are having trouble connecting to an specific access point and you want to try it manually, you can try using this script: http://wiki.laptop.org/images/4/44/Wpa.sh. Once this procedure is successful, you will not have to do it again as the settings will be remembered when you reboot.

Instructions:

  1. Copy http://wiki.laptop.org/images/4/44/Wpa.sh to a USB stick. (from a computer other than your XO)
  2. On your XO, open the terminal activity from the taskbar on the home page.
  3. Determine the name of your USB stick (if you do not know it), by typing:
  $ df
  1. Look for the line that starts with /dev/sda1 and read across to get the name of your USB stick. In this example the name is USBNAME.
  mtd0       1048576       375772  672804    36%  /
  tmpfs        35676            0   35676     0%  /dev/shm
  /dev/sda1   990432       331024   659408   34%  /media/USBNAME
  1. Copy the Wpa.sh file from the USB stick by substituting your USBNAME when typing this command. Note the period at the end of the command:
  $ cp /media/USBNAME/Wpa.sh .
  1. Execute the script as root by typing:
  $ su -
  # cd /home/olpc/
  # ./Wpa.sh
  1. If you get a "Permission denied" error, then use chmod, and try again
  $ chmod 777 Wpa.sh
  # ./Wpa.sh


  1. Follow the instructions on screen, providing the SSID, passphrase and WPA version of your Access Point. If you don't know the WPA version, try '1' first.
  2. Reboot the XO by typing:
  # reboot
  1. When it boots back up, go to the mesh neighborhood view and click on the circle of your AP, that should be showing as open now (no lock attached to the circle)
