Hi.

I am an absolute beginner to Ubuntu and to this forum, and i am not especially skilled in computers in general.
Just installed from the live cd today.
My problem is that i cannot get my wireless lan to work.
My laptop is a HP pavilion dv6000.
Hope somebody can help, or point me in the right direction
/René

There are a couple of things we can check. Go to the terminal (It's on the "Applications"-->"Accessories" menu) and type in the following, and let us know the results:

iwconfig

iwlist scan
These may help us start guiding you through setting things up.

Hey again.

Thanks for the quick answer. Sure an active community inhere.
Here's the results:

rene@rene-laptop:~$ iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

rene@rene-laptop:~$ iwlist scan
lo Interface doesn't support scanning.

eth0 Interface doesn't support scanning.

rene@rene-laptop:~$

Doesn't sound too promising. or?

Can you post the results of this from the terminal:

lspci -nn
This will give us the list of your PCI cards and this will help us figure out what wireless card you have.

This is your wireless card. The Linux Broadcom Driver (b43) does not support the wireless-n cards yet so you will need to use NDISwrapper.

Here is a link that might help:

I have an HP Pavilion ze2000 with Broadcom wireless card. I was having trouble getting my wireless card to work. Last night I upgraded to Ubuntu 7.10 (Gutsy Gibbon) and when I rebooted I was prompted at the desktop to install the driver. After another reboot it worked. The wireless blue light came on and everything.

type this at the command prompt to find what version of Ubuntu you are currently running: lsb_version

What version are you running?

Hey again.

Ayuthia > The link didn't provide much help - simply can't find out what to do?

mmelville3 > Where do i find the command prompt ?

July 2nd, 2008, 05:03 PM
I don't know exactly off hand. I'm sure it's under applications somewhere... I think its called Terminal. not command prompt.

René Haas

Then i type it in terminal:
rene@rene-laptop:~$ lsb_version
bash: lsb_version: command not found
rene@rene-laptop:~$
Whats wrong?

Ayuthia
Okay decided to give the link another go.
Just got frigthened by the technical apperence of the site.

Step 1

rene@rene-laptop:~$ echo 'blacklist bcm43xx' | sudo tee -a /etc/modprobe.d/blacklist
[sudo] password for rene:
blacklist bcm43xx

Sætter ndiswrapper-utils-1.9 (1.50-1ubuntu1) op...
rene@rene-laptop:~$ mkdir ~/bcm43xx; cd ~/bcm43xx
rene@rene-laptop:~/bcm43xx$

step 2

rene@rene-laptop:~$ lspci -n | grep '14e4:43'
03:00.0 0280: 14e4:4328 (rev 03)
rene@rene-laptop:~$

Which means that i should now make step 2d Right?

step 2d

rene@rene-laptop:~$ wget http://myspamb8.googlepages.com/R151517-pruned.zip
--17:56:16-- http://myspamb8.googlepages.com/R151517-pruned.zip

rene@rene-laptop:~$

Step 3
-- Okay made some errors here, but i hope it makes sence anyway

rene@rene-laptop:~$ sudo ndiswrapper -i bcmwl5.inf
driver bcmwl5 is already installed
rene@rene-laptop:~$ ndiswrapper -l
bcmwl5 : driver installed
device (14E4:4328) present
rene@rene-laptop:~$ sudo depmod -a
rene@rene-laptop:~$ sudo modprobe ndiswrapper
rene@rene-laptop:~$ sudo cp /etc/network/interfaces /etc/network/interfaces.orig
rene@rene-laptop:~$ echo -e 'auto lo\niface lo inet loopback\n' | sudo tee /etc/network/interfaces
auto lo
iface lo inet loopback

rene@rene-laptop:~$ sudo ndiswrapper -m
adding "alias wlan0 ndiswrapper" to /etc/modprobe.d/ndiswrapper ...

rene@rene-laptop:~$ echo 'ndiswrapper' | sudo tee -a /etc/modules
ndiswrapper
rene@rene-laptop:~$ echo 'ENABLED=0' | sudo tee -a /etc/default/wpasupplicant
ENABLED=0
rene@rene-laptop:~$

Last step

rene@rene-laptop:~$ lshw -C network

Okay. As i understand it the last line (configuration: should either say: "module=ssb" or "module=ndiswrapper" but is says latency=0

What has gone wrong.

I hope this long post make any sence at all, i am, as before mentioned very new to this stuff. And thansk to all who takes time to help me.

I'm only guessing now but look for something called restricted drivers under system > Adminstration.

Also, yesterday I found this article that more closely matches your situation:

After lot of frustration, and endless typing into the terminal my wireless network is now working.
Phew. I don't hope that using Ubuntu will remain to be this difficult.
But thanks a million for helping me out.

I have found it a struggle to get a few things working in Ubuntu. With Ubuntu you have to be willing to learn about the system as you go.
