Hi
I have some problem connecting if I don't follow some parameters
sequence in iwconfig command for example if I issues the following
# iwconfig wlan0 essid test ap xx:xx:xx:xx:xx:xx
#iwconfif wlan0 channel 9
in d80211 if essid and bssid set it will start authentication with
default channel and authentication will timeout then after the second
command kicks in to tune to the right channel the retry counter of
authentication will be at maximum and we wont authenticate, same problem
exist for IBSS it will start searching but once we call #iwconfif wlan0
channel 9 this will stop scanning and we stop IBSS searching . I
attached a patch for workaround this problem. I am not sure this is the
right way to fix just attached to illustrate the problem.
