RT2500 b/g driver for RT2500 b/g, Ralink Tech Corp.
=================================================================

The source code package verified for Linux version after RedHat Linux 7.1.



1) SETUP SEQUENCE
======================================================================
a. $tar -xvzf RT2500STA-Linux-1.1.0.tgz
    go to "./RT2500STA-Linux-1.1.0/Module" directory.
    
b. Use 'chmod' command to change access right of following script files :
   'load', 'unload', 'Configure'
 
c. $make config         # config build linux os version

d. $make all            # compile driver source code

e. $load                # load/insmod module(rt2500.o)

Note: Script functionality:
load            load module to kernel
unload          unload module from kernel
Configure       retrive linux version 

 
 
2) To BUILD UTILITY
======================================================================

a.  go to the "./Utility" directory

b.  run 'qmake -o Makefile raconfig2500.pro'
    If qmake command is not found in your system, you can download the QT tool 
    'qt-x11-free-3.2.1' or later at 
    http://www.trolltech.com/
    
    (qmake comes with RedHat 7.3 or later QT Package)    

c.  run 'make" to compile the utility source code.
   
d.  After all, an execution file would be generated "RaConfig2500"
    run "RaConfig2500" to config the driver as you want



3) CONFIGURATION
======================================================================
RT2500 driver can be configured via following interfaces, 
i.e. i)"iwconfig" command, ii)"iwpriv" command, iii) configuration file, iv) RaConfig2500

i)  iwconfig comes with kernel. Please refer file "iwconfig_usage.txt" for details.
ii) iwpriv usage, please refer to file "iwpriv_usage.txt" for details.
iii)copy configuration file "RT2500STA.dat" to /etc/Wireless/RT2500STA/RT2500STA.dat.
    Please refer to 3.1) for details.
iv) RT2500 provides API : RaConfig2500, please go to directory ./utility and refer to how-to-compile.txt

           
3.1) Configuration File : RT2500STA.dat

# Copy this file to /etc/Wireless/RT2500STA/RT2500STA.dat
# This file is a binary file and will be read on loading rt2500.o module.
#
# Use "vi -b RT2500STA.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 "OPEN", "SHARED", "WPAPSK", "WPANONE"
# 5.) EncrypType can be "NONE", "WEP", "TKIP", "AES"
# for more information refer to the Readme file.

4) MORE INFORMATION
=================================================================================
If you want for rt2500 driver to auto-load at boot time:
A) choose ra0 for first RT2500 WLAN card, ra1 for second RT2500 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 rt2500        
   
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
