Can you try the instructions for this module :

raygeeknyc,
Have you come across a list of wireless adapters that are supported “out of the box” with the BeagleBone? It seems like there would be such a list somewhere, but I haven’t had much luck in finding it.
Jerrill
I’m right there with you
same adapter
same problem
same question - this should not be this difficult
I purchased a new wireless adapter for the BeagleBone because my old one was less than stable and not natively supported. It works great on my Ubuntu laptop. Hopefully some one can shed some light on my wireless configuration problems with the BeagleBone with my new adapter. Here’s what I know:
- The USB device is “Belkin Components”
root@beaglebone:/etc# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 006: ID 05e3:0606 Genesys Logic, Inc. USB 2.0 Hub / D-Link DUB-H4 USB 2.0 Hub
Bus 001 Device 007: ID 05e3:0606 Genesys Logic, Inc. USB 2.0 Hub / D-Link DUB-H4 USB 2.0 Hub
Bus 001 Device 008: ID 050d:945a Belkin Components
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
- The driver that loads is the r8712u driver. I copied the firmware file from my Ubuntu machine…

…
WIN_ea80 { wifi_*******************_57494e5f65613830_managed_psk }
So here are my questions:
-
What am I missing to make this thing work?
-
Is there a “right” way (or at least a better/easier way) to manage wireless connection on the BeagleBone rather than go through all this?
-
Is there a way to connect to a WPA2-PSK access point from the command line? It seems like “connect SSID PSK” should be easy enough to accomplish since I can just select my access point an type a password to connect in Ubuntu. Surely someone at least has a script that does this.
-
I know I’m using Network Manager in Ubuntu and connman on the BeagleBone. Is there some difference between the two that is causing a problem?
-
Why isn’t this easier?
Thanks.
Jerrill

Jason,
Thank you for posting that link. It gave me a little more information on connman than I had before. UNFORTUNATELY, it did NOT resolve my problem. Is step #20 buy the Adafruit adapter?
Here’s what happened!
- Start over with the latest Angstrom demo image from the following site so I know that none of my previous attempts to get it working had broken anything:
http://www.angstrom-distribution.org/demo/beaglebone/
Here’s the image I loaded:
jerrill@JerrillUbuntuLT:~/Downloads$ sudo -s
[sudo] password for jerrill:
root@JerrillUbuntuLT:~/Downloads# xz -dkc Angstrom-Cloud9-IDE-GNOME-eglibc-ipk-v2012.05-beaglebone-2012.06.18.img.xz > /dev/sdb
-
I know that I won’t have any power issues with the wireless adapter. I have a 25 W power supply running the BeagleBone and a powered USB hub hosting the wireless adapter.
-
Boot the beagle bone with the new image.
-
Check my ethernet configuration:
root@beaglebone:~# ping www.google.com

- Update the package list from the internet:
root@beaglebone:~# opkg update
…
- Upgrade as per the instructions:
root@beaglebone:~# mkdir /home/root/tmp
root@beaglebone:~# opkg -t /home/root/tmp upgrade
…
- I noticed that everything was getting upgraded to kernel version 3.2.23 from the images original 3.2.18. (NOTE: This takes a while… I hope you have a fast SD card…) So, after the update I rebooted to make sure that the new kernel and upgraded modules were correctly loading…

-
Verify that the wireless dongle is plugged in and reboot.
-
Check dmesg and ifconfig for wireless. At this point is where we head off into a ditch again. No wlan0.

Ok! I have wlan0 now… back to the instructions from Adafruit…
- Configure connman to automatically manage wifi:
root@beaglebone:~# nano -w /var/lib/connman/settings
In my case the wifi setting was already set to ‘true’ so I left it alone…
[WiFi]
Enable=true
- Create the wifi settings file per the instructions:

root@beaglebone:~# cat /var/lib/connman/wifi.config
[service_home]
Type = wifi
Name = WIN_ea80
Security = wpa2
Passphrase = ***************************
- Restart connman to get it to accept the new settings:
root@beaglebone:~# systemctl restart connman.service
- Check to see if wlan0 connected:
root@beaglebone:~# ifconfig -a wlan0

Hmmm… no connection… not even after a reboot!
- I went ahead and installed the wireless tools again:
root@beaglebone:~# opkg install wireless-tools
- I tried iwconfig to see what it tells me:
root@beaglebone:~# iwconfig
