essid
Set the ESSID (or Network Name - in some products it may also be called Domain ID). The ESSID is used to identify cells which are part of the same virtual network.
As opposed to the AP Address or NWID which define a single cell, the ESSID defines a group of cells connected via repeaters or infrastructure, where the user may roam transparently.
With some cards, you may disable the ESSID checking (ESSID promiscuous) with off or any (and on to reenable it).
If the ESSID of your network is one of the special keywords (off, on or any), you should use -- to escape it.
Examples :
iwconfig eth0 essid any
$ lsmod | grep ath5k
ath5k 87680 0
$ sudo iwconfig wlan0 key off essid Golden_WiFi
$ sudo iwconfig wlan0
wlan0 IEEE 802.11bg ESSID:"Golden_WiFi"

Вот, что то получилось, далее мне нужно зайти на страничку GoldenWiFi, я так думаю dhclient запустить, но не выходит же:
$ sudo dhclient wlan0
