**** 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 ****

==========
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.

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.
