Hi,

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

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

Step 2: Please copy-paste the following command from the https://answers.launchpad.net/ubuntu website in Firefox into the Linux Terminal. Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command. The command STARTS with the word sudo and ENDS with the word restart. So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

sudo lshw -C network; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | grep ound; dmesg | grep b43; dmesg | grep wl; dmesg | grep witch; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo /etc/init.d/networking restart

Step 3: Please post results (copy/paste terminal output) on this thread

Step 4: Please also specify the exact model and make of your PC (if known) on this thread

Regards,

Mark

Dear Sir I have tried, by coping from sudo till restart. and then came out some thing like etho=etho.
then I wrote it on the next step. and then gave my pc model nr, but thing did not work.

now i am retrying it again but now it does not come out the result etho=etho. now each time i try now.

please tell me again. sorry for disturbing agian. any way with lan it is working. I need it with wifi, as asked in the question.

Dear sir from third step i cannot go forward, I have opened terminal where came out my computer name. Then I copy and paste from scud to restart, then gave my password. and then came out some result like etho=etho.

I continued and in the next step 3 wrote these etho=etho. and then gave the command Enter.
But i think failed

I will repeat the request one more time:

Please open a Terminal.

Copy-paste the following command into the Terminal:

sudo lshw -C network; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | grep ound; dmesg | grep b43; dmesg | grep wl; dmesg | grep witch; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo /etc/init.d/networking restart

Copy-paste the output from the Terminal AFTER running the whole command and paste the output in this thread.

We need to see the full Terminal output from running the above command.....

I am not providing a solution yet. I am requesting for more info using that command....

When I write: "on this thread', I mean: copy the output to this location (the current thread):

thank you sir, waiting

According to the output you sent, your wireless card is working correctly in Ubuntu and is using the right drivers. It has scanned and detected your wireless access point called ""Alice-76653511"

The problem could be that you have not yet set up the right wireless encryption password or encryption mode using NetworkManager.

Try disabling encryption and enabling SSID broadcasting on the wireless router to see if it helps you get a working wireless connection. If that works, then you know that the issue is with setting up an ENCRYPTED connection.

tahir (tahir152) said : #10

Thank you very much sir, It is now resolved, while i was trying it came out the window with asking the password then i entered the password. and it worked.thanks again.

just a minute sir, one question after installing ubuntu and while trying to solve this problem i installed RUTILT WALAN MANAGER
 is this that made it working or it would have worked even without this software.

or in other words after installing ubuntu, to solve this problem which software one has to choose to install to make it working From ubuntu software certer.

thanks for the extra time dedicating for me.
Regards. tahir.

Instead of changing the title of this thread, please create a separate question for the webcam issue using this link:

https://answers.launchpad.net/ubuntu/+addquestion

The current thread is already solved and that is why the title should remain "Wifi, connection to enable with Alice modem ITALY"

Currently, this thread is of no use to users visiting this thread, because the solution is not linked to the incident title anymore.

I will now change the incident title, or else the thread will not be useful for others.....

Hi Mark,

it seems that I have same problem as many other boys on my laptop. This modell is a HP nc6320 with BCM4312 and I am trying to up a Kubuntu 10.0 LTS . I skimmed a couple of answers for this issue on site and of course I tried to do what you suggested to anothers. But unfortunately didn't work until now.

1. I connected my machine to a wired network (this mail is being written on the laptop), install b43-fwcutter, restarted the NB but it still doesn't working. The card indicator LED doesn't light although press some times. (Besides there is on this machine Windows with dual boot and the wireless card and radio button are working properly.). At last I have run your recommended checking command(s) and you can't see the result:

nbz@nbz-laptop:~$ sudo lshw -C network; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | grep ound; dmesg | grep eth; dmesg | grep ath; dmesg | grep b43; dmesg | grep wl; dmesg | grep witch; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo /etc/init.d/networking restart
