<h1>wpa_supplicant configuration wizard</h1>
|
||
|
|
|
||
|
|
<p><a href="../">wpa_supplicant</a> supports large range of security
|
||
|
|
modes and authentication types. Just looking at the reference
|
||
|
|
information of available configuration options may not provide enough
|
||
|
|
high level understanding to select which options are needed. This page
|
||
|
|
provides information about configuring wpa_supplicant and a wizard for
|
||
|
|
generating example configuration files to make it easier to understand
|
||
|
|
different security policies and how they should be configured for
|
||
|
|
wpa_supplicant.</p>
|
||
|
|
|
||
|
|
<p>The wizard goes through steps to select suitable options based on
|
||
|
|
your input. An example configuration file is updated at each
|
||
|
|
step. This example can be seen at the bottom of this page.</p>
|
||
|
|
|
||
|
|
<h2>Step 1/5: Operating system and driver</h2>
|
||
|
|
|
||
|
|
<p>wpa_supplicant can be used with multiple operating systems and
|
||
|
|
network drivers. Most of the configuration parameters do not depend on
|
||
|
|
this, but some of the parameters may need to be changed based on
|
||
|
|
OS/driver capabilities.</p>
|
||
|
|
|
||
|
|
<form name="os_driver">
|
||
|
|
<select name="os" onChange="configure_os()" onBlur="configure_os()">

<h2>Step 2/5: Network name</h2>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
Wireless networks have a "network name" (SSID = Service Set
|
||
|
|
Identifier). This is a sequence of up to 32 characters. This name is
|
||
|
|
used to select which access points (AP) can be used and as such, it
|
||
|
|
must match with the SSID configured for the desired AP.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
Some APs allow SSIDs to be "hidden" which requires that the client is
|
||
|
|
specifically searching for the configured to SSID to be able to
|
||
|
|
connect. This may require some additional options in wpa_supplicant
|
||
|
|
configuration, so enable those here by checking "hidden SSID" if your
|
||
|
|
AP is configured to hide the SSID. This may show up as "brodcast SSID
|
||
|
|
disabled" or "hidden SSID" or something similar in the AP
|
||
|
|
configuration. Hidden SSID configuration does not prevent
|
||
|
|
wpa_supplicant from connecting to APs that do not hide SSID, so it can
|
||
|
|
be enabled for all cases.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<form name="network">
|
||
|
|
SSID: <input type="text" name="ssid" onChange="update_conf()">

Static WEP keys requires that at least one key is configured. Up to
|
||
|
|
four keys can be configured and one of them needs to be selected to be
|
||
|
|
used for transmitted frames. All configured keys can be used when
|
||
|
|
decrypting received frames.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
WEP can be used with different key length. In most cases, either
|
||
|
|
40-bit or 104-bit keys are used. These key lengths may also be shown
|
||
|
|
as 64-bit and 128-bit in some cases since WEP adds 24-bit
|
||
|
|
initialization vector into the keys. 40-bit keys can be entered as
|
||
|
|
five character string surrounded with double quotation marks, e.g.,
|
||
|
|
"abcde". Alternatively, they can be entered as a hex string of ten
|
||
|
|
characters without quotation marks, e.g., 6162636465. Both of these
|
||
|
|
options configure the same key. 104-bit keys are entered similarly,
|
||
|
|
with 13-character text string or 26-character hex string.

<p>
|

|
|
wpa_supplicant uses indexes 0 .. 3 for the WEP keys. Some other user
|
||
|
|
interfaces may use indexes 1 .. 4, so this needs to be taken into
|
||
|
|
account when determining which index to use here.
