I have a Beaglebone running Ubuntu 12.04.1 LTS with a Realtek Wifi USB dongle:

ubuntu@arm:~$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I am able to connect just fine to my Netgear R6300 with the following /etc/network/interfaces file:

auto lo
iface lo inet loopback

# WiFi Example
auto wlan1
iface wlan1 inet dhcp
    wpa-ssid "FalkorSystems"
    wpa-psk  "<omitted>"

However I am trying to connect to my Verizon MiFi device "Jetpack 4260L", and I'm not having any luck. I'm able to connect fine to the MiFi from my Mac. The MiFi is setup with WPA2, just like the Netgear R6300

auto lo
iface lo inet loopback

# WiFi Example
auto wlan1
iface wlan1 inet dhcp
       wpa-ssid "FalkorMifi"
       wpa-psk  "<omitted>"

I've also tried configuring the MiFi with an open network and I used:

auto lo
iface lo inet loopback

# WiFi Example
auto wlan1
iface wlan1 inet dhcp
       wireless-ssid "FalkorMifi"

I've also created an access point on my Mac using the instructions here:

http://www.dummies.com/how-to/content/how-to-make-your-mac-a-wifi-access-point.html

and I created it without any encryption, and I wasn't able to connect.

I would do:

> ifdown wlan1
> ifup wlan1

and the ifup command would hang.

I also tried rebooting rather than doing ifdown/ifup.

dmesg would tell me, when it connects successfully to my Netgear:
