• Tested in Redhat 7.3 or later and ubuntu Drapper Drake

Descrizione

This is a linux device driver for Ralink RT61 a/b/g WLAN Card.

Contents

Makefile.4 : Makefile for kernel 2.4 series

Makefile.6 : Makefile for kernel 2.6 series

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.

Installazione dei driver

1> $tar -xvzf RT61_Linux_STA_Drv_x.x.x.x.tar.gz

• go to "./RT61_Linux_STA_Drv_x.x.x.x/Module" directory.

2> $cp Makefile.4 ./Makefile # [kernel 2.4]

• or
• $cp Makefile.6 ./Makefile # [kernel 2.6]
  • or
  $cp Makefile.RTL865x ./Makefile # big endian platform

3> [solo per chi ha il kernel 2.4]

• $chmod 755 Configure $make config # config build linux os version

4> $make all # compile driver source code

5> $cp rt2561.bin /etc/Wireless/RT61STA/ # copy firmware

• $cp rt2561s.bin /etc/Wireless/RT61STA/ $cp rt2661.bin /etc/Wireless/RT61STA/

6> $dos2unix rt61sta.dat

• (dos2linux si può installare da Synaptic)
• $cp rt61sta.dat /etc/Wireless/RT61STA/rt61sta.dat
• # !!!check if it is a binary file before loading !!!

7> $load

• c'è lo script per caricare i driver nella distribuzione scaricata prima

• #[kernel 2.4]
  #    $/sbin/insmod rt61.o
  #    $/sbin/ifconfig ra0 inet YOUR_IP up 

• #[kernel 2.6]
  #    $/sbin/insmod rt61.ko
  #    $/sbin/ifconfig ra0 inet YOUR_IP up 

Note:

Script functionality:

load

load module to kernel 

unload

unload module from kernel 

Configure retrieve linux version

Configurazioni della scheda

Una volta configurata la scheda, possiamo settarla come predefinita settando i paramentri nel file /etc/network/interfaces:

• iface ra0
  inet dhcp
  wireless-essid [il proprio ESSID]
  wireless-key [la propria key]
  auto ra0
  #auto eth1 

RT61 driver can be configured via following interfaces,

i.e. (i)"iwconfig" command, (ii)"iwpriv" command, (iii) configuration file,

• (iv)RaConfig61

i) iwconfig comes with kernel.

ii) iwpriv usage, please refer to file "iwpriv_usage.txt" for details.

iii)copy configuration file "rt61sta.dat" to /etc/Wireless/RT61STA/rt61sta.dat.

iv) RaConfig61 is utility for rt61.

Configurazione rt61sta.dat

# Copy this file to /etc/Wireless/RT61STA/rt61sta.dat

# This file is a binary file and will be read on loading rt.o module.

#

# Use "sudo gedit rt61sta.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
