I need help in configuring wireless network on HP Pavilion dv4000

Hi,

Please first connect your network card to the wireless router using a LAN cable.

Then please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->
Terminal"

Step 2: Run the following commands (copy-paste each line below to the Terminal then hit <enter> after each line)

sudo iwlist scanning
nm-tool
iwconfig
ifconfig
sudo lshw -C network
lspci -nn
lsusb
uname -a
dmesg | grep ound
dmesg | grep witch

Step 3: Post results (cut/paste terminal output from each command) here

Regards,

Mark

First, let me point out that I have a dv9000, not a dv4000 so what worked for me may not work for you.

I had essentially the same problem. When I first did the install, everything seemed to go OK but some of the laptop's features didn't work, including the wireless and the webcam.

It turns out the solution, so to speak, was to do absolutely nothing.

In my case the system needed updated drivers that were not included on the install CD. After letting the system run for a few hours - plugged into the network cable - I eventually got an update notification. I applied the updates and gradually more and more features of the laptop became available.

Sometimes after you update, there will be more updates to follow.

Keep in mind that some peripherals - like wireless, which is still a peripheral even though it's "built in" - can only be accessed once the connecting hardware is correctly identified and has the appropriate drivers installed.

Consider this as an *EXAMPLE*

Suppose you had a wireless USB device on your system. You install Ubuntu and it installes the basic drivers. The problem is that the installation CD can't reasonably be expected to contain drivers for every conceivable piece of hardware out there so it only installs what it knows. This is your basic system.

It is possible on this example system that the basic drivers don't know how to handle the laptop's USB port so the FIRST round of updates will download new drivers for the USB sub-system. Once installed, the USB ports would then work. Notice that, in this example, the USB ports must be working first, before Ubuntu can even see the wireless USB device. As a result, after the FIRST round of updates, you still won't have wireless enabled because Ubuntu hasn't even seen that you have it yet.

The SECOND round of updates would then be able to see the wireless USB device in this example and only then would you have a chance of getting the correct drivers for it.

That, in a nutshell is what happened with my dv9000 - the first round of updates did NOT fix the wireless problem. I decided, in the end, to just let it sit online for a day and check it periodically for new updates and patches and install them whenever they appeared. I'm not sure at exactly what stage the wireless and webcam became operational but as far as I've checked it out, everything is now working.

So in short, make sure your system is fully updated and keep in mind what I said about some hardware not being "visible" to Ubuntu (applies to Windows too) until other hardware is detected first. Like me, you may have to go several rounds of updates to get the system fully operational.

I hope this helps. I'm a newbie myself so I'll leave this question to more experienced users if it turns out you've let all the updates install and still don't have a working system.

Good luck.
