=======================================================================
Ralink Hardware:
===================
Ralink 802.11n Wireless LAN Card.


=======================================================================
Description:
=============
This is a linux device driver for Ralink RT2870 USB ABGN WLAN Card.


=======================================================================
Contents:
=============
Makefile	        : Makefile
*.c					: c files
*.h					: header files


=======================================================================
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 ¡¥iwe_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

MORE INFORMATION
=================================================================================
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
