I remember that one of my friends (he's using a Compact laptop), he has to switch something (maybe the wireless card)before conecting to wifi., but i never switched anything into my laptop before i connect to wifi, it's automatic.i think, if im not wrong it's built in.

I did not see any button or switch that looks like the image you have given me

other people seem to have success running the following command

rfkill unblock all

Try that.

Please post the output from

Code:

lspci
lsmod |grep iwl
ifconfig
iwconfig

I'm lost here---and I imagine that you are too...

First, please give some more detail on you internet setup: Whose connection is it? Is there a wired connection available? (If not, can you somehow find a wired connection?---you will need that for several possible reasons.)

Second, did you run iwconfig? Here is mine:

Code:

[mherring@mystical log]$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

wmaster0  no wireless extensions.

wlan0     IEEE 802.11abgn  ESSID:""  
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
          Tx-Power=14 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

This tells us that there is wireless only on wlan0, but that it is not connected. If you get "no wireless extensions" for all interfaces, it means that the driver for your card is not installed. To check further, run these commands and post the output here:

Code:

lsmod|grep 3945

dmesg|grep 3945

find /lib -name  "*3945*"

If we find that the driver is not installed, you will have to find a wired connection to install it.

Stay with us---this probem WILL be fixed!!

You are referring to the | symbol---in Linux it is used to specify a pipe---it is very common when using the terminal

Look here and see if you can identify what keyboard layout you are using:

This means that you already have the wireless driver installed----the other commands will confirm this.

Have you tried "iwlist wlan0 scan"? (It might need sudo at the beginning.)

i think i have already tried this but it cant perform the scan because it's not connected in the internet.Thanks.
