Can't use SSH, so I'm trying to get the BeagleBone's WiFi up via serial
link (w/ console image). My failing method:
Create /etc/network/interfaces:
iface wlan0 inet dhcp
wpa-ssid "My_WiFi_SSID"
wpa-psk "My_WiFi_Password"
Enter commands:
sudo ip link set wlan0 up
sudo ifup wlan0
Resulting output:

No DHCPOFFERS received.
No working leases in persistent database - sleeping.
I notice that `sudo ip link set wlan0 up` isn't working (`ip link` shows
that wlan0 status is still DOWN). I'm stuck. Please help!
Thanks.
