Release Date: 2008-12-05, ver 1037

RTL8187L Linux driver version 1037

--This driver supports RealTek RTL8187L Wireless LAN NIC for

2.6 kernel:

Fedora Core 2/3/4/5/6/7, Debian 3.1, Mandrake 10.2/Mandriva 2006,

SUSE 9.3/10.1/10.2, Gentoo 3.1, etc, Ubuntu8.04/8.10.

2.4 kernel:

Redhat 9.2, etc

- Support Client mode for either infrastructure or adhoc mode

- Support WEP, WPAPSK and WPA2PSK connection

Component

The driver is composed of several parts:

1. Module source code

ieee80211

rtl8187

2. Script ot build the modules

Makefile

3. Script to load/unload modules

wlan0up

wlan0down

4. Script and configuration for DHCP

wlan0dhcp

ifcfg-wlan0

5. Supplicant source code:

wpa_supplicant-0.5.5.tar.gz

6. Example of supplicant configuration file:

wpa1.conf

Installation

<<Method 1>>

Runing the scripts can finish all operations of building up modules

from the source code, installing driver to the kernel and starting up the nic.

1. Build up the drivers from the source code

make

2. Install the driver to the kernel

make install

reboot

3. bring up wlan if nic is not brought up by GUI, such as NetworkManager

ifconfig wlan0 up

Note: use ifconfig to check whether wlan0 is brought up and use iwconfig to

check your wlan interface name,since it may change wlan0 to wlan1,etc.

<<Method 2>>

Or only load the driver module to kernel and start up nic.

1. Build up the drivers from the source code

make

2. Load driver module to kernel and start up nic.

./wlan0up

Note: when 'insmod: error inserting 'xxxx.ko': -1 File exists' comes out

after run ./wlan0up, please run ./wlan0down first, then it should

be ok..

Note: If you see the message of 'unkown symbol' during ./wlan0up, it

is suggested to build driver by <<Method 1>>.

Set wireless lan MIBs

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]

Show Power Management mode power

For example:

iwlist wlan0 channel

iwlist wlan0 scan

iwlist wlan0 rate

iwlist wlan0 power

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 mode essid 'name' mode Ad-hoc

iwconfig wlan0 key 0123456789 [2] open

iwconfig wlan0 key off

iwconfig wlan0 key restricted [3] 0123456789

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

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

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, We 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-0.5.5

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-0.5.5.tar.gz (e.g.)

cd wpa_supplicant-0.5.5

(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

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.

(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'

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'

}

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. Low kernel version which is lower than 2.6.18.rc2 may have trouble with

TKIP heavy traffic while SMP is configured. Please change your security

cipher or update your kernel.

4. According to documentaion 'wpa_supplicant.conf' provided by the package of

wpa_supplicant, ap_scan is set to 2 for IBSS connection. If user is trying to

associate to AP in Infrastructure mode, please unmark this line us as belowing

'#ap_scan=2'

(6)Execute WPA supplicant (Assume related modules had been loaded):

wpa_supplicant -D wext -c wpa1.conf -i wlan0 & (recommended)

wpa_supplicant -D ipw -c wpa1.conf -i wlan0

Note: At first, user sholud check Wireless Extension by typing 'iwconfig -v'

on the comment line. If the version of Wireless Extension is equal or

larger than 18, the option of '-D wext' is suggested. If the version

of Wireless extension is less than 18, the option of '-D ipw' is

suggested.

But before you use 'wext' or 'ipw' command, you sholud check which drivers

wpa_supplicant can support by typing command 'wpa_supplicant'. after typing the

comment line, you can see some infomations about wpa_supplicant are listed,

example:

---------------------------------------------------------------------------

usage:

XXXXXXXXX

drivers:

wext = Linux wireless extensions (generic)

atmel = ATMEL AT76C5XXx (USB, PCMCIA)

wired = wpa_supplicant wired Ethernet driver

options:

XXXXXXXXX

example:

XXXXXXXXX

---------------------------------------------------------------------------

The driver interface wpa_supplicant can support are listed in 'drivers',

if 'ipw' or 'wext' is not listed in it, you can only use the the other interface.

If the interface you want to use is not supported by wpa_supplicant. you can

follow steps (1)-(6), And in step (3) you must let:

CONFIG_DRIVER_IPW=y.

CONFIG_DRIVER_WEXT=y.

or both

CONFIG_DRIVER_IPW=y.

CONFIG_DRIVER_WEXT=y.

GPIO methord for Radio On/Off

1. The Change For Deliverring Power State:

Now we add the RadioPower.sh script in the driver root path.

When you run ./wlan0up or make install, this script will be copied

to /etc/acpi/events. And the driver can deliver the power

state 'RFON' or 'RFOFF' into /etc/acpi/events/RadioPower.sh from driver.

So you can change this script based on the power state RFON or RFOFF.

2. For Example:

Now the RadioPower.sh's content is:

if[ '$1' = 'RFON ]; then

echo '>Now Polling Method Turn RF ON!' > /etc/acpi/events/RadioPowerTest

else

echo '>Now Polling Method Turn RF OFF!' > /etc/acpi/events/RadioPowerTest

So when you turn on RF using Polling Method, you can see '>>Now Polling Method Turn RF ON!'

using command: cat /etc/acpi/events/RadioPowerTest.

And when you turn off RF using Polling Method, you can see '>>Now Polling Method Turn RF OFF!'
