Wifi Edimax EW 7711UTn

[Tazz]

Dobrý den. Mám koupenou Wifi Edimax EW 7711UTn. Systém jí rozpozná jako Ralink 802.11 n WLAN, ale nenajde žádnou wifi síť. Zkoušel jsem to na 3 počítačích s Ubuntu 9.10 nebo 10.04 a všude je výsledek stejný. V okolí je k dispozici dostatek bezdrátových sítí, ale nezobrazí se žádná.
K zařízení bylo CD s ovladačem pro linux, ale nejspíš jsem někde udělal chybu a stále to nefunguje.

Ovladač ke stažení zde: http://www.edimax.com/en/support_detail.php?pl1_idSelect=support.php%3Fpl1_id%3D1%26mwsp%3D1&pl1_id=1&pd_id=292&button=Go
Tady je soubor README_STA, podle kterého jsem postupoval, můžete mi prosím napsat postup jak by to mělo být správně? Díky!

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
  Please set 'HAS_WPA_SUPPLICANT=y' and 'HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y'.
** Build for being controlled by WpaSupplicant with Ralink Custom Event
  Please set 'HAS_WPA_SUPPLICANT=y' and 'HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n'.
  command: #./wpa_supplicant -Dralink -ira0 -c wpa_supplicant.conf -d

4> $make # compile driver source code

5> $cp RT2870STA.dat  /etc/Wireless/RT2870STA/RT2870STA.dat
    
6> load driver, go to "os/linux/" directory.
    #[kernel 2.4]

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.

Už jsem byl fakt zoufalý, nevím jak jsem to mohl přehlédnout.
Takže řešení:

Kód: [Vybrat]

sudo bash
echo blacklist rt2800usb > /etc/modprobe.d/blacklist-wifi.conf
depmod -a

Ahoj, mám problém se stejným usb adaptérem. Jsem úplnej začátečník, ubuntu jsem si nainstaloval včera večer a to čistě z nouze. No a ten adaptér se mi teď ani nezobrazuje, takže jsem bez netu. Chtěl bych se zeptat na tři věci.

1) skutečně neexistuje jednodušší způsob, jak to připojení zprovoznit, než podle tohohle návodu ?

2) Pokud to nejde, může se z něj aspoň  vynechat část "configuration"? Pevně doufám, že jo, protože z tý už nechápu naprosto nic

3) Co to znamená   "define the GCC and LD of the target machine, define the compiler flags CFLAGS
   modify to meet your need."?
