I have since given up and switched to Ubuntu, which includes support for this dongle natively. I was able to bitbake a version of the distribution that included the driver, but was unable to build or find a version of the firmware that would work in Angstrom. This was really disappointing to me, since I had already made quite an investment in learning all about Angstrom. I ordered a NetGear WNA1100 but soon discovered that it won't run in the Angstrom distribution, which by default doesn't provide the ath9k_htc driver and associated firmware. Robert Nelson suggested that I try using a dongle using an Atheros chipset. I don't know if or why the people who wrote these are getting reliable WiFi - I sure didn't. Most of the online tutorials about how to get WiFi running on the Bone are using these dongles. These are very common, widely available, and appear at first glance to have the best software support on the Bone, at least in the standard Angstrom distribution. Long story short, I believe that most of my problems stemmed from attempting to use dongles based upon the rtl8192cu chipset (I tried several different ones). It was really unclear to me if the problem was hardware or software related, or some combination of the two. There's a lot of online frustration about this, some of which I contributed to. I kept seeing weird behavior, such as randomly dropped or stuttering connections, and different symptoms depending upon whether the WiFi dongle was plugged directly into Bone, into an extension cable, or into a powered hub. I have been trying for over a month to get reliable WiFi working on the original BeagleBone and now on the new BeagleBone Black.
