1. How do I know what Hardware my computer has?

Open a Terminal Window (Console) and use these commands to get
more information on your hardware, wireless, Windows loaded drivers,
and Linux drivers that are currently blacklisted. Copy & Paste to
prevent errors!


lspci
lsusb
lshw -C network
lsmod
ndiswrapper -l
cat /etc/modprobe.d/blacklist.conf
iwconfig

iwconfig will show what the wireless is detected as......wlan0, ath0, etc.
If you are requesting help, post the output of each command........

Are you sure that the Wifi is ENABLED? Is there a Switch or Special
Keystrokes (maybe CNTL F2) that turns it ON/OFF?


You could try to manually configure the Wifi Interface, if it is ENABLED.

Manual Configure:
If you know the routers essid and the correct <interface>,
shown by using iwconfig ie wlan0, ath0, etc.... replace that
as the <interface> below:


sudo ifconfig <interface> down
sudo dhclient -r <interface>
sudo iwconfig <interface> essid "youressidofrouter"
sudo iwconfig <interface> mode Managed
sudo ifconfig <interface> up
sudo dhclient <interface>
iwconfig

example......for Airlink and Wlan0
sudo iwconfig Wlan0 essid "Airlink"

hello, I tried with iwconfig and the result is:

lo no wireless extensions.

eth0 no wireless extensions.

eth1 unassociated ESSID: off/any
Mode:Managed Channel=0 Access Point: Not-Associated
Bit Rate:0 kb/s Tx-Power=20 dBm Sensitivity=8/0
Retry limit:7 RTS thr: off Fragment thr: off
Power Management: off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

pan0 no wireless extensions.

so the manual configuration didn't work
what now? thanx, pollo

It appears you didn't read the posing correctly....
Copy and Paste each command in a Terminal Window (Console):


lspci
lsusb
lshw -C network
lsmod
ndiswrapper -l
cat /etc/modprobe.d/blacklist.conf
iwconfig

If you are requesting help, post the output of each command........

We need that information to know what your Hardware, Drivers, etc. are.

Does the dv4000 connect to the internet on window, have you turn off the wireless card itself?

I'm sorry, in windows the wireless card works correctly, so it's not that I turned it out.
following, the output of all the commands in terminal

OK, it appears that you have ndiswrapper installed along with the Broadcom
bcmwl5 driver installed. I assume you are not wanting to use the Windows
Broadcom Drivers for the Wifi hardware you have installed, because it
won't work using them. Plus you must remove these to get the proper drivers
functional.

Let's clean up the Windows drivers by removing them along with ndiswrapper.

Open a Terminal Window (Console):

REMOVE WINDOWS DRIVERS:
If you want to REMOVE the Windows Drivers:...............
If the output of ndiswrapper -l shows any drivers loaded,
remove ALL of them. If memory serves me correctly the command is:


sudo ndiswrapper -e bcmwl5

This should clean up nidswrapper & drivers and:


ndiswrapper -l

should return nothing as being loaded.

Then remove ndiswrapper:


sudo modprobe -r ndiswrapper

Remove from startup file by editing:


sudo nano /etc/modules

to remove ndiswrapper.

Once you have this corrected, and ndiswrapper -l (MINUS LOWERCASE "L") try:


sudo /etc/init.d/networking restart

or reboot. You should have the Wifi functional. If it isn't move your mouse over
the Wifi Icon in the Top Right Toolbar, then RIGHT click and ENABLE the WIFI.
It must be ENABLED.


You're Wifi is a:
Intel Corporation PRO/Wireless 2200BG [Calexico2] Network Connection (rev 05)
and hopefully Ubuntu has selected the proper Drivers...........
configuration: broadcast=yes driver=ipw2200 driverversion=1.2.2kmprq firmware=ABG:9.0.5.27 (Dec 12 2007) latency=128 maxlatency=24 mingnt=3

To try and Manually set up the Wifi try:

MANUAL SETUP:
If you know the routers essid and the correct <interface>,
shown by using iwconfig ie wlan0, ath0, etc.... replace that
as the <interface> below:


sudo ifconfig <interface> down
sudo dhclient -r <interface>
sudo iwconfig <interface> essid "youressidofrouter"
sudo iwconfig <interface> mode Managed
sudo ifconfig <interface> up
sudo dhclient <interface>
iwconfig

example......for Airlink and Wlan0


sudo iwconfig Wlan0 essid "Airlink"

It shouldn't take more than about 15 minutes......
