Broadcom Wireless Setup for Hardy (Step by step)

RE: Need help with wifi connection for laptop COMPAQ Presario V3637AU

Hi there! =)

I installed Ubuntu 8.04 on my Compaq V3637AU laptop with AMD sempron processor.

I was unable to connect via wifi so I tried using wired DSL but I encountered the same problem.

Here are my findings so far which I hope would be of help.

I noticed the wifi indicator does not turn on.
The device driver profile does not show the wifi driver.
I did the hardware test and
it showed two devices:

Broadcom Corp BCM94311MCG wlan mini PCI (rev02)
nVidiaCorp MCP67 Ethernet (vera2)

But the hardware driver profile revealed the NVIDIA accelerated graphics driver (latest cards)

I am such a greenhorn with Ubuntu yet I am driven to master it and promote it those laptop users I know.

I looked at the forums and the Ubuntu help guides like:

http://www.foogazi.com/2008/04/28/ho...in-ubuntu-804/

yet I can't make my wifi or the wired dsl connection work on my laptop. =(

I hope someone can help me out on this. I am in the San Diego Calif area somewhere in National City.

I would greatly appreciate the help from any Ubuntu expert at this time so I can get my laptop connected to the internet.

Thank you very much and more power!

I think that 8.04.1 works with the b43 driver, but 8.04 did not. Since you don't have a working internet connection, that complicates things a little. I say this because this guide needs you to have cabextract and I don't recall that being on the install CD. You might be better off trying the Broadcom wl driver. If you have a computer that has a working internet connection, you can try this link:

You might also need to install build-essential. To do this, you will need your install CD. In the Terminal:

sudo apt-cdrom add

It will ask you for your install CD. Once that is complete, do the following in the Terminal:

sudo apt-get update
sudo apt-get install build-essential

What these commands will do is add the CD package information into your computer. It will then update your computer and then install build-essential. Build-essential contains packages that will allow your computer to compile some programs.

If you don't want to do this from the Terminal, you should be able to do this through Synaptic (the Ubuntu package manager). There should be a menu item that will allow you to manage repositories. Once it is selected, there should be an option to add the CD. Unfortunately, I can't guide you too well in there. I currently don't have Synaptic installed (KDE desktops don't use Synaptic).

If you get stuck, you might want to post where you are stuck in the other link. This is because you are using the wl option instead of ndiswrapper.

Can you go into the Terminal and check to see the wireless chipset:

lspci -nn

If it says [14e4:4315] you will need to try either the wl driver or else this link:
https://help.ubuntu.com/community/Wi...eisty_No-Fluff

Otherwise, have you tried removing the encryption from your router?

well here is the result to dmesg | grep ndiswrapper:

You are right, my wirelesse chipset says [14e4:4315].
I give a look at the link you gave me and there is the same chipset working, but for BCM4310 and mine is BCM4312.
Is there any diference? If i install that drivers do you think it's going to work?

Thanks for the replies!

The 4310 and 4312 are the same. It was just labeled incorrectly before. You should try using that driver and see what happens. It has worked for some.

[adramalech]

could it be i am using the wrong version of the driver??? because everything seems to do what it should do....but it seems that the lights are on but no one is home kindof thing...

You might try another driver. The 4318 cards are hard to configure in Ubuntu for some reason.

You might even try posting on this thread:
http://ubuntuforums.org/showthread.php?t=870086

The driver for this thread is the same as the no-fluff thread but I can't seem to see why it is not working. I suggest posting on the other thread because Jamie Jackson might be able to see something that I am missing.
