thanks for all the information. My way to reliable wifi on the bone took me 3 days and 3 nights, it was a really hard job. The best explanation was given from Carl Johnson in his first post.
Now, almost one year later, I did it this way: I do not use Angstrom, it works, but only 1 of 10 times. Both, Debian and Ubuntu work, I finally switched to Ubuntu because of the more complete repositories. * download: http://rcn-ee.net/deb/rootfs/saucy/ (the latest image) * as Carl already told us, I installed the image according this description: http://embeddedprogrammer.blogspot.de/2012/10/beaglebone-installing-ubuntu-1210.html this page also shows how to test if the Wifi stick is recognized by the system. Important: * NEVER usw the N150 Micro-Sticks. These sticks work, but not reliably. * The bigger USB stick mentioned by Carl works perfect: NETGEAR N150 Wi-Fi USB Adapter (WNA1100) to setup the wlan I opened the file /etc/network/interfaces and added: auto wlan0 iface wlan0 inet dhcp wpa-ssid "MYSSID" wpa-psk "MyPassPhrase" and the same for wlan1 ! For any reason the stick was wlan0 or wlan1, I don't know why, so I configured both. VERY IMPORTANT: the bone has a CPU governor which switches the CPU frequency automatically. This makes any sort of problems, not only with wifi but also with other applications. Therefore it must be switched off using this command: cpufreq-set -c 0 -g performance Also I disabled HDMI and eMMC in the uEnv.txt file. The command is already included in the original file, just remove the #. Don't forget to press the boot button on the bone, otherwise it will use the uEnv.txt file from the eMMC. Now I removed the LAN cable, repowered the bone, and after a minute the bone got the IP via DHCP and I was able to SSH via wifi. (The LAN cable must be removed, it makes problems if wifi and wired lan is used simultaneously). With all this settings I wrote a script which copies a 100MB file between the bone and my PC via wireless SSH. I copied some 100GB of data, without any problems. The CPU load (tested with htop in another terminal) goes up to 100% during copying, but all works very stable. The end of the story is: * don't use Angstrom * don't use Micro-USB-Wifi-Sticks -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
