========================    
    AIROHA (AL2230/AL7230)

Function Supported
=================
    1. Support 802.11 a/b/g station functions 
    2. Support wireless extension interface(WE-17).(ex. iwconfig, see Note 1) 
    3. Support supplicant(STA) wpa/wpa2 with wpa_supplicant-0.4.9 (see Note 2)    

Installation
============
    Please enter the following commands at the UNIX prompt. Remember, UNIX is
    case sensitive and make sure your root login.

    1) Create a temporary directory:
        mkdir /temp

    2) Change to the temporary directory:
        cd /temp

    2) Copy driver (vntwusb.tgz) from DOS disk, (mcopy below is one tool in
       mtools, if you didn't install mtools, you can type 
       'mount -t msdos /dev/fd0 /mnt' and use 'cp /mnt/vntwusb.tgz /temp'
       command to copy the driver to the temporary directory):
        mcopy a:vntwusb.tgz .

    3) untar the archive file:

        tar xzvf vntwusb.tgz
        cd vntwusb
                         
    5) Compile the source files and it will generate './driver/vntwusb.ko' and 
       './ioctl/wetctl'. The file 'vntwusb.ko' will copy to driver installation 
       path and'wetctl' will copy to '/sbin/wetctl'. 
       
        make clean
        make install
        
    6) Check configuration file (/etc/modules.conf or /etc/conf.modules,it 
       depend on your Linux distribution) for loading kernel modules. Make sure
       there is the following content in the configuration file, where # is 
       interface number (eg: alias eth0 vntwusb):
        alias eth# vntwusb

    7) Configure/Modify the wireless settings. 
        
       Edit the 'sta.wlan' script files under path '/vntwusb' for required 
       wireless settings. 
       
       'sta.wlan' is an example for startup a wireless station.
       

    8) Reboot now:
        shutdown -r now
        
    9) Plug USB device    
        
    10) Install your driver module (If the driver module is in the wrong place,
       an error message will appear, and say that can't find the driver 
       module):
        insmod vntwusb

    11) Use ifconfig command to assign the IP address, where # is network 
       interface number:
        ifconfig eth# <IP>
        
    12) Run 'sta.wlan' script file to setup wireless connection:
         ./sta.wlan
        
    13) You can use 'wetctl' tools to check link status:
         /sbin/wetctl eth# link
        
        Or use wirelss extension tools 'iwconfig':
         iwconfig eth#

    14) Check the interface works:
         ping <remote_host_IP>
        
    15) Shutdown & remove driver:
         ./remove
        
  
Uninstallation
==============
    Please enter the following commands to uninstall your driver:
        make uninstall

Note
======

            
    1) You can use 'iwconfig' wireless tools (from 'wireless_tools.xx' package)
       in your Linux distribution to configue the wireless settings. 
       
       For example, to join a Access Point called "TestAP":

        /sbin/iwconfig eth# mode managed essid TestAP

       To scan available Access Point:
 
        /sbin/iwlist eth# scanning |more 		
       
       The kernel 2.6x already supports Wireless Extension Interface under
       X windows; you can use the network configure pannel to configure 
       wireless settings and network parameters(like ip,gateway).These 
       parameters will be used at boot time.

       More details see Linux user Manual, or type: 

        man iwconfig
        
        
    2) For wpa_supplicant installations:
       First untar the archive file 'wpa_supplicant-0.4.9-patch.tar.gz' then 
       follow the steps described in file 'README' to build & install this 
       freeware.  
       
        cd /wpa_supplicant
        tar xzvf wpa_supplicant-0.4.9-patch.tar.gz
       
       The 'wpa_supplicant-0.4.9-patch.tar.gz' contains the extra file:
       'driver_viawget.c' which is interface driver dedicated for 'vntwusb'
       linux driver.
