Hi,

You could try this:

For the AP, execute the following commands:

 ·          *sudo service network-manager stop           # Disable the
Network Manager.*

·         *sudo wlanconfig ath0 destroy*

·         *sudo wlanconfig ath0 create wlandev wifi0 wlanmode ap*

·         *sudo iwconfig ath0 essid 'name'*

·         *sudo* *iwconfig ath0 channel 6*

·         *sudo ifconfig ath0 up*

·         *sudo ifconfig ath0 169.255.1.2*

For the Station, execute the following commands:

·         *sudo service network-manager stop *

·         *sudo wlanconfig ath0 destroy*

·         *sudo wlanconfig ath0 create wlandev wifi0 wlanmode sta*

·         *sudo iwconfig ath0 essid 'name'*

·         *sudo* *iwconfig ath0 channel 6*

·         *sudo ifconfig ath0 up*

·         *sudo ifconfig ath0 169.255.9.2*

Hope this helps...
