**** beneath is a very helpful and well written help file, but if you are using rt3070usb, please replace every rt2870 with rt3070, Ralink's engineer(s) is(are) too lazy to correct the file ***

下面是读我文档, 照做就可以编译安装好 rt3070usb 的驱动了, 记得看见 rt2870 的时候把它换成 rt3070来理解, 雷凌的人太懒了 ****

ModelName:
===========
RT2870 Wireless Lan Linux Driver


=======================================================================
Driver lName:
===========
rt2870.o/rt2870.ko


=======================================================================
Supporting Kernel:
===================
linux kernel 2.4 and 2.6 series. 
Tested in Redhat 7.3 or later.


=======================================================================
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 DPB_RT2870_Linux_STA_x.x.x.x.tgz
    go to "./DPB_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

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
   
=======================================================================
Dongle/Clone Features:
======================
A) Dongle mode: 
    Provides a 1-to-N MAC address mapping mechanism such that more than one PC behind the STA 
    can transparently connect to the AP.

B) Clone mode:
 Provides a 1-to-1 MAC address mapping mechanism. 
 STA can use own MAC as SA MAC or 
   use user desired MAC as SA MAC or
      use source MAC of first packet coming from wired device as SA MAC.
 NOTE: In this mode, only the PC who own the specified MAC can connect to the AP.

 
C) Hybrid mode(Dongle+Clone):
 Provides a 1-to-N MAC address mapping mechanism such that more than one PC behind the STA 
    can transparently connect to the AP.
 STA can use own MAC as SA MAC or 
   use user desired MAC as SA MAC or
      use source MAC of first packet coming from wired device as SA MAC.

D) Please refer to "Config STA to link as dongle mode..." in iwpriv_usage.txt for releated commands.
