"sudo lshw -C network" Can't find my wireless device (card).

[jlunse]

I have a wired connection on the motherboard and a also a card for wireless communication.
Wired connection works fine but my plan is now to setup wireless connection too.

I was advised to use this in order to find installed network devices:

sudo lshw -C network

Not sure, but I think it only reports details about the wired device. Is that correct?
How could I get ubuntu to also find my wifi-card?

This is the report I get with sudo lshw -C network:

***Updated below***
Also tried this command on my daughters computer who also have two network devices, one wired (works fine in ubuntu) and one wireless connection (not working). This is what's reported by "sudo lshw -C network" and I can't find any wireless device in this text, or am I missing something?

I found a graphical tool called lshw-gtk and installed it using Package Manager.
Then I have to start it using sudo lshw-gtk
(starting it as a ordinary user might not report all information)

Anyway, it seems like it found my wireless card but with a strange error in the end. This is what's reported:

What does this error mean?

Does this mean that's there no driver available for this wifi device? Should I give up at this point?

Anyway, I also investigated this further by using WinXP and found the following information for Wireless PCI 802.11b/g adapter WN4201B:
Provider: PCTEL Inc.
Driver Provider: Accton
Driver Date: 2004-11-30
Driver Version: 2.0.2.2

Also found an "inf file" in WinXP called WN4201B (c:\i386\drv\APP270044\src\WN4201B.inf)
Could I use this "inf file" in Ubuntu?

Note! This guideline was really useful for installing my wifi driver:
Wi-Fi Card Activation Under Ubuntu Linux Using ndisgtk and Windows Drivers (http://kimbriggs.com/computers/computer-notes/linux-notes/ubuntu-linux-wi-fi-card.file)

Seems like I was lucky and managed to install the windows driver by using the following steps:

1. Install ndiswrapper (http://en.wikipedia.org/wiki/NDISwrapper) using Package Manager.

2. Install ndisgtk (http://en.wikipedia.org/wiki/Ndisgtk#Graphical_frontends) using Package Manager.

3. Install lshw-gtk using Package Manager.

4. Copied the WinXP folder (c:\i386\drv\APP270044\src) with the wireless driver to Ubuntu.

5. sudo ndisgtk and installed the driver by selecting the "inf-file": WN4201B.inf

6. sudo lshw-gtk

7. Navigate to the PCI adapter and it now shows the following information and without the ugly "this device hasn't been claimed" error:

Also, configuration of the Wireless Network was successful and I describe it in this thread:

What are the first basic steps to setup a wireless connection? (http://ubuntuforums.org/showthread.php?t=1547859)

[bkratz]

Sorry was out, post 9 gives the details of what I wanted to show you, but it looks like you did it fine without it.

You might go to the thread tools and mark as solved in case it helps someone else.

No problem:) Your information is good and I think understand now. An adapter's driver could be installed in two different ways in ubuntu and lubuntu:


Using Window XP driver: Installed by using Ubuntu's ndiswrapper and with the windows driver (*.inf file) as described above (This solved my problem in lubuntu 10.04).
Note! Switching between wired/wireless requires a reboot.

Using Linux driver: Installed by using linux-firmware-nonfree-1.6. (I also tested this for the same wifi adapter in ubuntu 10.04 and it was also successful).
This works better for me since it seamlessly switches between wired/wireless without having to reboot.


If non of the above works, then I think you have to replace the physical adapter/device with one having a commercial linux driver.
