Hi Guys,

i have a problem with hostapd, i installed using this guide

http://en.tacticalcode.de/2013/03/use-y ... or-ap.html
I choose bridge mode

after i reboot the pi and i execute the command " hostapd -dd /etc/hostapd/hostapd.conf "
I get the following output, in particular

Code: Select all

nl80211: Failed to set interface 3 to mode 3: -16 (Device or resource busy)

I think your issue is rather here: "Could not add bridge br0 : Invalid argument"

AFAIK, "inet manual" in /etc/network/interfaces is now hijacked by dhcpcd.
Look at the interfaces conf in this post. The AP worked (finally) and we're using "static" with no further configuration for eth0 and wlan0. (which is silly I know, but hey...)
