Parameters

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

iwconfig eth0 essid "My Network"

iwconfig eth0 essid -- "ANY"

nwid/domain

Set the Network ID (in some products it may also be called Domain ID). As all adjacent

wireless networks share the same medium, this parameter is used to differentiate them

(create logical collocated networks) and identify nodes belonging to the same cell.

This parameter is only used for pre-802.11 hardware, the 802.11 protocol uses the ESSID

and AP Address for this function.

With some cards, you may disable the Network ID checking (NWID promiscuous) with off

(and on to enable it again).

Examples:

iwconfig eth0 nwid AB34

iwconfig eth0 nwid off

nick[name]

Set the nickname, or the station name. Some 802.11 products do define it, but this is not

used as far as the protocols (MAC, IP, TCP) are concerned and completely useless as far as

configuration goes. Only some wireless diagnostic tools may use it.

Example:

iwconfig eth0 nickname "My Linux Node"

mode

Set the operating mode of the device, which depends on the network topology.

The mode can be:

o Ad-Hoc (network composed of only one cell and without Access Point)

o Managed (node connects to a network composed of many Access Points, with

roaming)

o Master (the node is the synchronization master or acts as an Access Point)

o Repeater (the node forwards packets between other wireless nodes)

o Secondary (the node acts as a backup master/repeater)
