So, I’ve done my homework and scoured many places looking for a solution but have come up short. I am trying to setup a wifi direct connection with an Android device and I have not been able to get my wifi usb dongle to work…some information:

I have a Rev A5 Beaglebone running

1) https://www.google.com/search?q=SIOCSIFFLAGS%3A+Operation+not+possible+due+to+RF-kill

so: sudo rfkill list all

2) Android does handle wifi by itself, so why are you trying to
start it from the commandline?

Thanks for the reply Vladimir.

Sorry about the confusion. I am using an android with ICS to connect to the beaglebone over a
belkin N150 micro usb wifi direct. The rfkill won’t lift

Still no success with the wifi…and this morning I tried the new image @ http://downloads.angstrom-distribution.org/demo/beaglebone/
and when it boots I get an error…

Uncompressing Linux… done, booting the kernel.
[ 0.224029] _omap_mux_get_by_name: Could not find signal leds-gpio
[ 0.524627] omap_hwmod: wkup_m3: wkup_m3: hwmod data error: OMAP4 does not support st_shift

is this specific to my board or is this image not suitable for the beaglebone?
