Open a terminal (Applications, Accessories, terminal) and type "lspci" without the quotes and copy and paste the result here.
This will give us the list of your devices so that we can see what wireless card you have.

Can you see the wireless network device in Network manager (the menu that comes up if you (right) click on the system tray icon)? At what stage does it fail?

Is there a system tray icon about proprietary drivers? If so, can you click on it, and make sure that the driver for the wireless card is in use?

[I have a Broadcom 4318 wireless chipset in my laptop--I know that for 8.04, the "bcm43xx" driver has been replaced by "b43". It still works, for me, however, albeit with some failures (but it's a few years old, so I don't know that that's software rather than hardware)]

andee32 (andee32) said : #4

No wireless network device show in the network manager.

Thomas Kluyver (takluyver) said : #5

if you run the command "jockey" (or "jockey-kde" for kubuntu), does it offer you an option to install a driver for the card?

andee32 (andee32) said : #6

not for the Broadcom 4318 wireless... only NVIDIA graphics card...

Thomas Kluyver (takluyver) said : #7

Can you try:
sudo aptitude install b43-fwcutter
lsmod | grep b43
(post results)

If that doesn't show anything, try:
sudo modprobe b43

Thomas Kluyver (takluyver) said : #9

That suggests that the driver is loaded and everything. Can you post the contents of /etc/network/interfaces

andee32 (andee32) said : #10

andy@andy-laptop:~$ /etc/network/interfaces
bash: /etc/network/interfaces: Permission denied

Thomas Kluyver (takluyver) said : #11

Nope, that's a file, not a command. If you can find a way to attach files here, you can attach it, otherwise open it to show the contents, and copy and paste them here. (for example, you could use "cat /etc/network/interfaces").

andee32 (andee32) said : #12

andy@andy-laptop:~$ cat/etc/network/interfaces
bash: cat/etc/network/interfaces: No such file or directory

there is no file and no directory

Thomas Kluyver (takluyver) said : #13

No, there's a space in that command: "cat /etc/network/interfaces". So you're running the command "cat" (which, in this context, just shows you the content of the file) on the file "/etc/network/interfaces".

If it's easier, you can just open the text editor of your choice (e.g. gedit, or kate on KDE), and open the file /etc/network/interfaces

andee32 (andee32) said : #14

andy@andy-laptop:~$ cat /etc/network/interfaces
auto lo
iface lo inet loopback

iface eth0 inet dhcp

auto eth0

Shang Wu (shangwu) said : #15

Actually, I will need to see the output of following command:

lspci -vvnn | grep 14e4:4328

If it shows up, here is what you need to do:

1. Install the ndiswrapper, ndisgtk packages

2. Download the driver from the following URL:
ftp://ftp.hp.com/pub/softpaq/sp36501-37000/sp36684.exe
Extract it

3. System> Administration> Windows Wireless Devices and select the *.inf file to install the driver.

andee32 (andee32) said : #16

andy@andy-laptop:~$ lspci -vvn | grep 14e4:4328
03:00.0 0280: 14e4:4328 (rev 03)

how do I extract the file once it is downloaded?
2. Download the driver from the following URL:
ftp://ftp.hp.com/pub/softpaq/sp36501-37000/sp36684.exe
Extract it

Thomas Kluyver (takluyver) said : #18

(I would say the b43 drivers are a better bet, but I'll leave it to you.)

andee32 (andee32) said : #19

This driver is allowing me to finally see the wireless networks but they go in and out... Will the other driver work better? If so what do i need to do next to get the b43 driver to work?

Thomas Kluyver (takluyver) said : #20

It looked like they were loaded before, so I don't actually know why it wasn't showing up in Network Manager...

Shang Wu (shangwu) said : #21

do the following command and post the output:

lsmod

I suspect that you might need to put some driver into the blacklist.

andee32 (andee32) said : #22

what do I need to do next?

Shang Wu (shangwu) said : #23

do the following command and post the output:

lsmod
