unable to net with build in wireless card on laptop
I am getting obsessed with Linux OS up to the point of starting to swap MS OS.
I opened WICD and it show (Wired network = 0 wired-default VVV
and wireless network = C STR ESSID ENCRYPT BSSID MODE CHNL
is this meaning that build in wireless card is or is not recognized?
I will keep looking for info, although is hard to learn a new OS from scratch
can anyone please!!! slap me in the neck with a how to for dummy/newbie.

One way to see information on your wireless card would be to use the iwconfig command for example:



lo        no wireless extensions.

eth0      no wireless extensions.

irda0    no wireless extensions.

eth1      IEEE 802.11g  ESSID:"netname" 
          Mode:Managed  Frequency:2.437 GHz  Access Point: 00:26:B5:44:36:00 
          Bit Rate:54 Mb/s  Tx-Power=20 dBm  Sensitivity=8/0 
          Retry limit:7  RTS thr:off  Fragment thr:off
          Power Management:off
          Link Quality=75/100  Signal level=-54 dBm  Noise level=-91 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0  Missed beacon:0

Notice eth1 has information regarding a wireless card and the others simply say no wireless extensions. To find out more information, type at the command prompt:


man iwconfig

It would help if you post which distribution you are using. We also need the output of

distro is Ubuntu... and after command lspci
I'm getting
0 ethernet controller: broadcom corporation BCM4401-B) 100Base-TX rev 02)
0 cardBus bridge: 02 Micro, Inc. 0Z711EC1 SmartCardBus Controller rev 20)
1 CardBus Bridge: 02 Micro, Inc. 0Z711EC1 SmartCardBus Controller (rev 20)
0 Netork controller: Intel Corporation PRO/Wireless LAN 2100 3BMini PCI Adapter (rev 04)

this is matching info from MS OS

I have been working for ours trying to enable the wireless card, I might be missing a lot of steps and the biggest one might be misusing the info + rushing myself in learning an OS completly new to me. I am putting all my spare time in learning, but is not ease. if someone please suggest me what I need to know first at least to have my wireless internet up.

Thank very very very much in advance to any/all/everyone who takes the time to read and try to help
