User Guide(1) - connecting wireless networking using "Network Manager" GUI utility
==============================================================================================
(1) Network Manager is a utility attempts to make use of wireless networking easy.
(2) Notes: if you want to use the following command-line method to connect wireless networking,
please disable the "Network Manager", because "Network Manager" will conflict with method of command line .
===============================================================================
User Guide(2) - Set wireless lan MIBs in Command Line
===============================================================================
This driver uses Wireless Extension as an interface allowing you to set
Wireless LAN specific parameters.
Current driver supports "iwlist" to show the device status of nic
iwlist wlan0 [parameters]
where
parameter explaination [parameters]
----------------------- -------------
Show available chan and freq freq / channel
Show and Scan BSS and IBSS scan[ning]
Show supported bit-rate rate / bit[rate]
For example:
iwlist wlan0 channel
iwlist wlan0 scan
iwlist wlan0 rate
Driver also supports "iwconfig", manipulate driver private ioctls, to set
MIBs.
iwconfig wlan0 [parameters] [val]
where
parameter explaination [parameters] [val] constraints
----------------------- ------------- ------------------
Connect to AP by address ap [mac_addr]
Set the essid, join (I)BSS essid [essid]
Set operation mode mode {Managed|Ad-hoc}
Set keys and security mode key/enc[ryption] {N|open|restricted|off}
For example:
iwconfig wlan0 ap XX:XX:XX:XX:XX:XX
iwconfig wlan0 essid "ap_name"
iwconfig wlan0 mode Ad-hoc
iwconfig wlan0 essid "name" mode Ad-hoc
iwconfig wlan0 key 0123456789 [2] open
iwconfig wlan0 key off
iwconfig wlan0 key restricted [3] 0123456789
Note: Better to set these MIBS without GUI such as NetworkManager and be sure that our
nic has been brought up before these settings. WEP key index 2-4 is not supportted by
NetworkManager.
===============================================================================
Getting IP address
===============================================================================
After start up the nic, the network needs to obtain an IP address before
transmit/receive data.
This can be done by setting the static IP via "ifconfig wlan0 IP_ADDRESS"
command, or using DHCP.
If using DHCP, setting steps is as below:
(1)connect to an AP via "iwconfig" settings
iwconfig wlan0 essid [name] or
iwconfig wlan0 ap XX:XX:XX:XX:XX:XX
(2)run the script which run the dhclient
./wlan0dhcp
or
dhcpcd wlan0
(Some network admins require that you use the
hostname and domainname provided by the DHCP server.
In that case, use
dhcpcd -HD wlan0)
===============================================================================
WPAPSK/WPA2PSK - using wpa_supplicant
===============================================================================
Wpa_supplicant helps to secure wireless connection with the protection of
WPAPSK/WPA2PSK mechanism.
If the version of Wireless Extension in your system is equal or larger than 18,
WEXT driver interface is recommended. Otherwise, IPW driver interface is advised.
Note: Wireless Extension is defined us "#define WIRELESS_EXT" in Kernel
Note: To check the version of wireless extension, please type "iwconfig -v"
If IPW driver interface is used, it us suggested to follow the steps from 1 to 6.
If wpa_supplicant has been installed in your system, only steps 5 and 6 are required
to be executed for WEXT driver interface.
To see detailed description for driver interface and wpa_supplicant, please type
"man wpa_supplicant".
(1)Download latetest source code for wpa supplicant or use wpa_supplicant-0.6.9
attached in this package. (It is suggested to use default package contained
in the distribution because there should less compilation issue.)
Unpack source code of WPA supplicant:
tar -zxvf wpa_supplicant-0.6.9.tar.gz (e.g.)
cd wpa_supplicant-0.6.9
(2)Create .config file:
cp defconfig .config
(3)Edit .config file, uncomment the following line if ipw driver interface
will be applied:
#CONFIG_DRIVER_IPW=y.
(4)Build and install WPA supplicant:
make
cp wpa_cli wpa_supplicant /usr/local/bin
NOTE:
1. If make error for lack of <include/md5.h>, install the openssl lib(two ways):
(1) Install the openssl lib from corresponding installation disc:
Fedora Core 2/3/4/5(openssl-0.9.71x-xx),
Mandrake10.2/Mandriva10.2(openssl-0.9.7x-xmdk),
Debian 3.1(libssl-dev), Suse 9.3/10.0/10.1(openssl_devl),
Gentoo(dev-libs/openssl), etc.
(2) Download the openssl open source package from www.openssl.org, build and
install it.
2. If make errors happen in RedHat(and also Fedora Core) for kssl.h,
please add lines below into Makefile
CPPFLAGS+=-I/usr/kerboros/include
(5)Edit wpa_supplicant.conf to set up SSID and its passphrase.
For example, the following setting in "wpa1.conf" means SSID
to join is "BufAG54_Ch6" and its passphrase is "87654321".
Example 1: Configuration for WPA-PWK
network={
ssid="BufAG54_Ch6"
#scan_ssid=1 //see note 3
proto=WPA
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP WEP104 WEP40
psk="87654321"
priority=2
}
Example 2: Configuration for LEAP
network={
ssid="BufAG54_Ch6"
key_mgmt=IEEE8021X
group=WEP40 WEP104
eap=LEAP
identity="user1"
password="1111"
}
Example 3: Linking to hidden ssid given AP's security policy exactly.(see note 3 below)
ap_scan=2
network={
ssid="Hidden_ssid"
proto=WPA
key_mgmt=WPA-PSK
pairwise=CCMP
group=CCMP
psk="12345678"
}
Example 4: Linking to ad-hoc (see note 4 below)
ap_scan=2
network={
ssid="Ad-hoc"
mode=1
proto=WPA
key_mgmt=WPA-NONE
pairwise=NONE
group=TKIP
psk="12345678"
}
Note: 1. proto=WPA for WPA, proto=RSN for WPA2.
2. If user needs to connect an AP with WPA or WPA2 mixed mode, it is suggested
to set the cipher of pairwise and group to both CCMP and TKIP unless you
know exactly which cipher type AP is configured.
3. When connecting to hidden ssid, explicit security policy should be given with
ap_scan=2 being setting.
4. It is suggested setting ap_scan to 2 and mode to 1 when linking to or creating an ad-hoc. Group and pairwise
cipher type should also be explicit, always with group setting to TKIP or CCMP and pairwise setting
to NONE. Lower version wpa_supplicant may not allow setting group to CCMP with pairwise setting to NONE.
So if any problem, you may try to set both group and pairwise to CCMP, leaving other setting unchanged, when
connecting to an CCMP-encrypted ad-hoc.
5. More config setting option, please refer to wpa_supplicant.conf in wpa_supplicant.tar.gz that we provide.
(6)Execute WPA supplicant (Assume driver and related modules had been
loaded):
./runwpa
Note: The script runwpa will check Wireless Extension version automatically.
If the version of Wireless Extension is equal or larger than 18, the
option of "-D wext" is selected. If the version of Wireless extension
is less than 18, the option of "-D ipw" is selected.
===============================================================================
WPS - PIN & PBC methods
===============================================================================
(*) please see the "README-WPS" file in the package "wpa_supplicant-0.6.9.tar.gz"
to perform the WPS function.
===============================================================================
Power Saving Mode
===============================================================================
(1) in order to enter PS Mode, you need to add the parameter of "power_mgnt=1" when executing "insmod 8712u.ko" :
~#insmod 8712u.ko power_mgnt=1
or
~#insmod 8712u.ko power_mgnt=2
(2) Notes:
power_mgnt=0 ;//default, disable PS
power_mgnt=1 ;//enable PS, MIN_PS Mode
power_mgnt=2 ;//enable PS, MAX_PS Mode |
