"repeater mode" in the DD-WRT

If you want to repeat the network from an another AP，you can set the wireless->basic-setting->"Wireless Physical Interface" to "client" or "client bridge","repeater" or "repeater bridge".the difference between these can be searched. what I want to say is above all you must set setup->Basic setup-> WAN Connection Type->connection type in "DHCP" mod。 because without this the dd-wrt cannot acquire IP address from the another AP,which you want to repeated。

how to config wireless with iwconfig

1. list the wireless ap
iwlist scan
2. set the $ssid name of ap
iwconfig wlan0 essid $ssid
3. set the $key of wep
iwconfig wlan0 key s:$key --> ascii mod
iwconfig wlan0 key xxxx-xxxx-xx --> hex mod
4. specify the ap's mac
iwconfig wlan0 ap xx:xx:xx:xx:xx:xx

obtain ip address from:
dhclient wlan0

why kismet shows "FATAL:Unknown capture source type..." error

you must install the libpcap BEFORE the compiling kismet from source.

and, when you ./configure with the "--disable-setuid" option will be helpful,becouse with this you did not assign the "suiduser“ in kismet.conf。
