=======================================================================

Features:

==========

This driver implements basic IEEE802.11. Infrastructure and adhoc mode with

open or shared or WPA-PSK or WPA2-PSK authentication method.

NONE, WEP, TKIP and AES encryption.

=======================================================================

Build Instructions:

====================

1> $tar -xvzf RT2870_Linux_STA_x.x.x.x.tgz

go to "./RT2870_Linux_STA_x.x.x.x" directory.

2> In Makefile

set the "MODE = STA" in Makefile and chose the TARGET to Linux by set "TARGET = LINUX"

define the linux kernel source include file path LINUX_SRC

modify to meet your need.

3> In os/linux/config.mk

define the GCC and LD of the target machine

define the compiler flags CFLAGS

modify to meet your need.

** Build for being controlled by NetworkManager or wpa_supplicant wext functions

Please set 'HAS_WPA_SUPPLICANT=y' and 'HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y'.

=> #>cd wpa_supplicant-x.x

=> #>./wpa_supplicant -Dwext -ira0 -c wpa_supplicant.conf -d

** Build for being controlled by WpaSupplicant with Ralink Driver

Please set 'HAS_WPA_SUPPLICANT=y' and 'HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n'.

=> #>cd wpa_supplicant-0.5.7

=> #>./wpa_supplicant -Dralink -ira0 -c wpa_supplicant.conf -d

4> $make

# compile driver source code

# To fix "error: too few arguments to function ˉiwe_stream_add_event"

=> $patch -i os/linux/sta_ioctl.c.patch os/linux/sta_ioctl.c

5> $cp RT2870STA.dat /etc/Wireless/RT2870STA/RT2870STA.dat

6> load driver, go to "os/linux/" directory.

#[kernel 2.4]

# $/sbin/insmod rt2870sta.o

# $/sbin/ifconfig ra0 inet YOUR_IP up

#[kernel 2.6]

# $/sbin/insmod rt2870sta.ko

# $/sbin/ifconfig ra0 inet YOUR_IP up

7> unload driver

$/sbin/ifconfig ra0 down

$/sbin/rmmod rt2870sta

CONFIGURATION:

====================

RT2870 driver can be configured via following interfaces,

i.e. (i)"iwconfig" command, (ii)"iwpriv" command, (iii) configuration file

i) iwconfig comes with kernel.

ii) iwpriv usage, please refer to file "iwpriv_usage.txt" for details.

iii)modify configuration file "RT2870STA.dat" in /etc/Wireless/RT2870STA/RT2870STA.dat.

Configuration File : RT2870STA.dat

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

# Copy this file to /etc/Wireless/RT2870STA/RT2870STA.dat

# This file is a binary file and will be read on loading rt.o module.

#

# Use "vi RT2870STA.dat" to modify settings according to your need.

#

# 1.) set NetworkType to "Adhoc" for using Adhoc-mode, otherwise using Infrastructure

# 2.) set Channel to "0" for auto-select on Infrastructure mode

# 3.) set SSID for connecting to your Accss-point.

# 4.) AuthMode can be "WEPAUTO", "OPEN", "SHARED", "WPAPSK", "WPA2PSK", "WPANONE"

# 5.) EncrypType can be "NONE", "WEP", "TKIP", "AES"

# for more information refer to the Readme file.

#

#The word of "Default" must not be removed

If you want for rt2870 driver to auto-load at boot time:

A) choose ra0 for first RT2870 WLAN card, ra1 for second RT2870 WLAN card, etc.

B) create(edit) 'ifcfg-ra0' file in /etc/sysconfig/network-scripts/,

edit( or add the line) in /etc/modules.conf:

alias ra0 rt2870sta C) edit(create) the file /etc/sysconfig/network-scripts/ifcfg-ra0 DEVICE='ra0' ONBOOT='yes' NOTE: if you use dhcp, add this line too . BOOTPROTO='dhcp' *D) To ease the Default Gateway setting, add the line GATEWAY=x.x.x.x in /etc/sysconfig/network
