Re: wi-fi intel 3945



Buenas...

a luta continua!


Oi de novo Raul. Olha só, eu instalei o iwl3945 e o firmware-iwlwifi.

eu tbm..

rlonghi@thc:~$ sudo dpkg -l|grep iwl
ii  firmware-iwlwifi  0.11   Binary firmware for Intel Wireless
 
rlonghi@thc:~$ sudo dpkg -l|grep firm
ii  firmware-iwlwifi  0.11   Binary firmware for Intel Wireless

a interface sobe..

eu suponho que todo esse rolo esteja relacionado a isso. Tá erro na firmware. Pior que já baixei outras versões mas só piorava a situação.

rlonghi@thc:~$ dmesg |grep iwl

Saudações,

Saída do lsmod na minha máquina:
$  lsmod | grep 3945

iwl3945                84712  0
firmware_class          9312  1 iwl3945
mac80211              114380  1 iwl3945
Você já verificou com lsmod se está tudo certo? Se estiver, configure a wi-fi com ip fixo:

1 - $ sudo iwconfig wlan0 essid xxxxxxx
2 - $ sudo iwconfig wlan0 channel xx
3 - $ sudo iwconfig wlan0 key restricted xxxxxxxxxxxxxxxxxxxxxxxx
4 - $ sudo ifconfig wlan0 up
5 - $ sudo ifconfig wlan0 xxx.xxx.xxx.xxx netmask 255.xxx.xxx.xxx broadcast xxx.xxx.xxx.xxx
6 - $ sudo route del default
7 - $ sudo route add default wlan0
8 - $ sudo route add default gw xxx.xxx.xxx.xxx
9 - $ sudo /etc/init.d/networking restart

Resumidamente, foi como funcionou minha wi-fi. Depois surgiram alguns problemas com gateway. Mas, antes de falar sobre isso, vamos ver se sua wi-fi funciona.
Depois dos procedimento acima, tente fazer um ping na sua placa e veja se foi realmente configurada.
