Unable to connect to the internet

[wobert]

Hello I got some weeks trying to connect my M4400 dell to the internet without success.
Kubuntu 10.04 @64 bits was installed.

These is the information from my network card:

0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
0c:00.0 0280: 14e4:4315 (rev 01)


I followed the instruction from a couple of threads related to my network card without success
(http://wireless.kernel.org/en/users/Drivers/b43, etc.)
I will really appreciate your help

Re: Unable to connect to the internet

is local network working or don't you have network at all?

What's the output of ifconfig -a ??

Re: Unable to connect to the internet

from here:
https://help.ubuntu.com/community/Wi...xx/#Installing b43/STA hybrid drivers
you may need to install the given package bcmwl-kernel-source then try using the Hardware Drivers app to activate it (or install the package b43-fwcutter in a terminal)

But the http://wireless.kernel.org/en/users/Drivers/b43
says your device needs 2.6.33 or newer kernel, 10.04 has 2.6.32, so I dunno if it will work. or if the info is outdated

Re: Unable to connect to the internet

I have no network at all (I am connecting through another computer).

This is the output:

I don't mean to be obnoxious, but do you have your wifi card physically turned on?

That happened to me before , thus my "stupid" question

Re: Unable to connect to the internet

Multiple threads with the same problem.

Some of it has to do with Network Manager and wireless connections.

Try plugging your computer into a wired ethernet connection and connecting. If that works, consider dumping Network Manager and installing Wicd instead:

sudo apt-get remove network-manager-kde
sudo reboot
sudo apt-get autoremove

sudo apt-get install wicd

Then everything worked for me.

Re: Unable to connect to the internet

One of the first things I checked was to ensure the switch from wireless was on.
I have also tried connecting via ethernet without success.

I am really getting crazy because I just can not connect and have tried several procedures...

The only clear thing so far is to never acquire a network card from this brand, is there a prefer brand for kubuntu?
After so much time wasted I am considering the possibility of buying another one (I want to completely leave windows now!)

Re: Unable to connect to the internet

My old Gateway m675prr had a bcm4312, which I eventually gave to my 9 year old grandson this summer. I've used ndiswrapper to install it and I've used the Hardware Drivers menu option (with an ethernet connection from the back of the wireless router. (Which, you say, doesn't work either.)

First add

blacklist b43
blacklist b43legacy
blacklist b43 ssb
blacklist ssb

to /etc/modprobe.d/blacklist


Can you access the broadcom *.inf and *.sys files from your Windows side?
(Keep in mind that if you are running 64bit then use the 64bit drivers.)

if you are using 64-bit LINUX, you MUST use 64-bit XP drivers with your 64-bit NDISwrapper; using 32-bit drivers will not work. You will get, "driver loaded, device present" when you ndiswrapper -l, but you will get no interface wlan0. A dmesg | grep ndiswrapper will show you ndiswrappers complaining that it can't use the 32-bit drivers; I have no idea why ndiswrapper -l will simply say "driver loaded, device present"

If you want a graphic gui front end to ndiswrapper you can install ndisgtk

If so, if you can download the deb packages for ndiswrapper:
ndiswrapper-utils-1.9 and
ndiswrapper-common
and install them via a USB stick or cdrom?

Then you could cd to directory where you copied the Windows *.inf and *.sys files and issue
sudo ndiswrapper -i bcmwl5.inf (or what ever it's called now)

Then list the driver to see if both the driver AND the hardware are present:
do
sudo ndiswrapper -l
and it's supposed to say:

"bcmwl5 driver present, hardware present"

but IF all it says is:
"bcmwl5 driver present"
then it didn't install and you may be using the wrong version of the driver for your hardware.

IF the "hardware present" part is listed then issue:

sudo sudo ndiswrapper -m

which should turn on your wireless and allow you to use wicd or something to connect. If your wireless light doesn't come on try
sudo modprobe ndiswrapper

If it does come on then issue
sudo depmod -a
to make it permanent.
