Here's a video of the Beagle Gadget communicating over wireless... and... browsing the web using ... drum roll ... Firefox. That's crazy. I remember the days when I was lucky to get a serial communication link going on my PalmOS Treo handheld, let alone wifi. But suffice to say, here it is, actually working:
Here's how I was able to do it:
Step 1: Format the SD card
I followed the instructions here, and made a formatted BeagleBoard SD card with the updated OS that include the kernel module to get WIFI working.
For the more hackerishly inclined, here's a direct link to the kernel image and to the rootfs image.
For reference, these links are also at the bottom of the BeagleBoard page :
Step 2: Attach the USB ethernet module
I used this USB Wifi module, so at least if you have this one, you're guaranteed to work...
I took it out of the case by cracking it open with a screw driver - not because it added anything, but just because it looks a lot cooler that way.
I plugged it into the small USB hub, but only because I also wanted to plug in a USB mouse and mini keyboard. Otherwise there wasn't really any particularly good reason to use the USB hub - I could have plugged the USB wifi module directly into the Beagle Board.
Step 3: Configure the wifi settings
There are also some more detailed instructions on the wiki for this next step...
Once it was plugged in, and Linux was booted up, I edited the file at /etc/wpa_supplicant/wpa-supplicant.conf. This file contains the parameters for the wifi adapter module, and mine looks something like this:
ssid="<your ssid here>"
psk="<your password here>"
Step 4: Turn on wifi
This is the easiest step of all... simply issue this command:
$ ifup wlan0
And then issue this command:
$ ping www.liquidware.com
$ ping www.apple.com
And here's another video showing off Firefox actually browsing on the Beagleboard Linux Gadget:
