DFS start_dfs_cac() failed, -1

[Todd Lewis]

Thanks, I figured it out. I had  a couple things wrong. I didn't know
i had to recompile crda  with the keys generated when the regulatory
database is compiled. I'm not sure if everything I did is correct /
necessary, but it works.

I ened up doing the following.

# Compile regulatory database
cd /usr/src/
git clone git://git.kernel.org/pub/scm/linux/kernel/git/sforshee/wireless-regdb.git
cd wireless-regdb/
make  && make install

#Compile  CRDA  , must use the keys generated by regulatory database
cd /usr/src/
git clone git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/crda.git
cp /usr/lib/crda/pubkeys/*  /usr/src/crda/pubkeys/
make && make install

#Setup up Regulatory Domain  to US
echo "REGDOMAIN=US"  > /etc/default/crda
echo "options cfg80211 ieee80211_regdom=US"  > /etc/modprobe.d/cfg80211.conf
iw reg set US
