Bug Description
On Linaro Android 13.12 release image:

WiFi doesn't work on TI Panda 4430. The access point can be listed but after clicked it and typed password, a pop-up window shows:
Failed to connect to network.
"wpa_cli" command set doesn't work either:
root@pandaboard:/ # busybox ifconfig eth0 down
root@pandaboard:/ # svc wifi enable

This issue can be possibly walked around by following procedures:
1. Power on the board;
2. Turn off Ethernet (# busybox ifconfig eth0 down)
3. Turn on WiFi;
4. Connect to AP;
5. If step 4 failed, reboot the board, do step 2 and 4 again, until it can be done.
However, "UNKNOWN COMMAND" still shows up in console while using wpa_cli, which didn't happen in past.
