Hello everybody, I am quite new in BBB's world and I feel stuck in a
ridiculous way as I am not able to connect BBB by WIFI, by editing
/etc/network/interfaces and as I am trying to connect with and WPA WIFI, I
ought to edit the file /etc/wpa_supplicant/wpa_supplicant.conf .
I want to have BBB WIFI and able to change SSID, PSK, IP, NETMASK.... and
so on, just using node js which modifies the interfaces and
wpa_supplicant.conf files and restarting the wlan0 interface, so tools
like wicd or connman (I used them and worked perfectly) are not the best
way as them limit the way to change settings.
I've been trying almost everything I found over Internet, with no results.
*STARTING POINT:*
- Beaglebone Black Rev C
- Distributions used:
- Debian GNU/Linux 8.3 Jessie (I rather prefer to use this)
- Kernel 4.1.15-ti-rt-r43
- Debian 8.2 Jessie (is a tester distribution so I prefer not to
use this one)
- Debian 7.9 Wheezy (If anything goes well, I wont reject using
this)
- USB WIFI Adapter TL-WN722N & AWUS036H
- WIFI with WPA2-Personal
After all, I ll show you my results about following the next guide with a
cleaned and unused Debian 8.3. http://elinux.org/BBBWiFiConfigs I know
this tuto was tested with UWN100/200 USB WIFI adapter and with a Debian
7.4. Despite all I ll try it...
1. First of all I checked my ethernet connection is running with Connman.
*connmanctl> services*
**AO Wired ethernet_689e19571caf_cable*
* Wired gadget_689e19571ca0_usb*
*connmanctl> technologies*
*/net/connman/technology/gadget*
* Name = Gadget*
* Type = gadget*
* Powered = True*
* Connected = False*
* Tethering = False*
*/net/connman/technology/ethernet*
* Name = Wired*
* Type = ethernet*
* Powered = True*
* Connected = True*
* Tethering = False*
2. As said in General Instructions I didn't plug the WiFi device and all
steps are performed as root user.
3. Create file /etc/wpa_supplicant/wpa_supplicant.conf with WPA settings.
Inside the speech-marks I put my SSID and PKS (aplhanumeric not hexadecimal)
*ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="my-ssid"
scan_ssid=1
psk="my-psk"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
auth_alg=OPEN
}*
4. I saved the file.
5. Lets go to identify my interface name, first :
ifconfig -a
*can0 Link encap:UNSPEC HWaddr

6. Then I plug the USB Adapter TL-WN722N and repeat ifconfig -a, and show
the text before and....just the same... so I decided to reboot and try
again with the USB plugged from start. And nothing happens....
7. I jumped to modify /etc/network/interfaces file, this is my default
interfaces.
*# This file describes the network interfaces available on your system*
*# and how to activate them. For more information, see interfaces(5).*
*# The loopback network interface*
*auto lo*
*iface lo inet loopback*
*# The primary network interface*
*#auto eth0*
*#iface eth0 inet dhcp*
*# Example to keep MAC address between reboots*
*#hwaddress ether DE:AD:BE:EF:CA:FE*
*# The secondary network interface*
*#auto eth1*
*#iface eth1 inet dhcp*
*# WiFi Example*
*#auto wlan0*
*#iface wlan0 inet dhcp*
*# wpa-ssid "essid"*
*# wpa-psk "password"*
*# Ethernet/RNDIS gadget (g_ether)*
*# Used by: /opt/scripts/boot/autoconfigure_usb0.sh*
*iface usb0 inet static*
* address 192.168.7.2*
* netmask 255.255.255.252*
* network 192.168.7.0*
* gateway 192.168.7.1*
8. I saw that interface wlan0 is commented, maybe thats why iwconfig says:
*root@beaglebone:/etc/wpa_supplicant# iwconfig -a*
*-a No such device*
and ifconfig doesn't show anything similar to wlan0.
9. I ll modify interfaces unccomented just WiFi Example, this is my new
interfaces.
*# This file describes the network interfaces available on your system*
*# and how to activate them. For more information, see interfaces(5).*
*# The loopback network interface*
*auto lo*
*iface lo inet loopback*
*# The primary network interface*
*#auto eth0*
*#iface eth0 inet dhcp*
*# Example to keep MAC address between reboots*
*#hwaddress ether DE:AD:BE:EF:CA:FE*
*# The secondary network interface*
*#auto eth1*
*#iface eth1 inet dhcp*
*# WiFi Example*
*auto wlan0*
*#iface wlan0 inet dhcp*
*# wpa-ssid "essid"*
*# wpa-psk "password"*
*# Ethernet/RNDIS gadget (g_ether)*
*# Used by: /opt/scripts/boot/autoconfigure_usb0.sh*
*iface usb0 inet static*
* address 192.168.7.2*
* netmask 255.255.255.252*
* network 192.168.7.0*
* gateway 192.168.7.1*
10. Now I can reboot or sudo /etc/init.d/networking restart , I'll reboot
to be more confident, later I would use allow-hotplug wlan0 line, lets
check. After rebooting shows:
*root@beaglebone:~# ifconfig -a*

11. No wlan0 is showed up, next step, modify /etc/network/interfaces file
as shown in tutorial: They say to place these four lines at the top of the
file.... TOP ? is this necessary, I ll do it whatever I believe that order
doesn't mean to change nothing.
*allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp*
I will comment with # auto wlan0 before too, not to create any
conflict?¿?¿? The final interfaces file shows as...
*allow-hotplug wlan0*
*iface wlan0 inet manual*
* wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf*
*iface default inet dhcp*
*# This file describes the network interfaces available on your system*
*# and how to activate them. For more information, see interfaces(5).*
*# The loopback network interface*

*iface lo inet loopback*

*#iface eth1 inet dhcp*
*# WiFi Example*
*#auto wlan0*

*iface usb0 inet static*
* address 192.168.7.2*
* netmask 255.255.255.252*
* network 192.168.7.0*
* gateway 192.168.7.1*
12. With USB WIFI adapter inserted I run the next command:
root@beaglebone:/etc/network# ifup wlan0
Remains a little thinking and nothing happens... as said in tutorial I ll
power down safely, pressing S3 switch BBB. Unplug the Ethernet cable and
power back up.
Aaaaand ladies and gentlemen, when BBB power back again it shows like this:
<https://lh3.googleusercontent.com/-ueWF5k68MWQ/VrMgzwqgggI/AAAAAAAAAP8/lhGv3g4GhaI/s1600/IMG_20160127_112853.jpg>
USB WIFI ADAPTER IS ON but green light isn't blinking, so I know it is not
sending and recieving data.
iwconfig and ifconfig, shows....
