Unable to connect to internet on Ubuntu 11.04
 
I am really new to any Linux OS and I can not connect to the internet (I have wireless network) and it works nicely on Windows 7 on this notebook, but it doesn't find it on ubuntu. Any idea how to do it, as simply as possible? (My notebook is HP 550 if that's any help.)

Hello,

We need to know what kind of device you have, and what drivers are currently loaded for it. Run the following in a terminal, and post the output for us, using code tags please:
Code:
ifconfig
iwconfig
lspci -v
lsmod
Cheers,

Josh

I'm hoping I did it correctly...

The output you posted from the iwconfig command shows your wireless is recognized. The last part of your most recent post shows the wireless card info (part of it is posted below)

What exactly have you done to configure it? What happened? Error messages? Warnings? Nothing? I have not used Ubuntu 11.04 but, an earlier version had an icon in the upper right of the Desktop which you could click to try to set up internet. Do you have that? Have you tried it?

Hello DrArroganto,

I have a laptop with same card in it and works almost out of the box on the various *buntu's out there, every time when I upgrade to the next it seems easier.

in the beginning i needed to install WICD and NDISWRAPPER with GTK so I could then use the windows driver called BROADCOM43xx.inf. Nowadays I just go to 'additional drivers' while plugged in with a cable to my router to get connected and let it download these drivers. These days support under Ubuntu for this card is pretty good with the open drivers and have become my preferred choice. in the process can also install (although I don't use it myself any more) the built in dial up modem and graphics card drivers for '
proper open gl support.

so my question to you is, have you tried this option?

regards
Ron

Try typing
Code:
sudo rmmod b43-pci-bridge
sudo rmmod ssb
And then either
Code:
sudo modprobe brcm80211
or
Code:
sudo modprobe brcmsmac
What this does is unload the old broadcom driver which required a propietary firmware and load a newer open source one which doesn't require any propietary firmware but is only compatible with a small group of wifi chipsets (the bcm4313 that my laptop uses is one of the compatible chipsets).

It says that Firmware is missing...
@fbsduser It says error (Something is missing)
@wabbalee any idea where to get them? lol

Try your package manager and make sure you have all repositories enabled

All were enabled.. :/

You need to install the package firmware-b43-lpphy-installer for that device.

Lol.. Can you send the link for the download? Can't find it in the software center nor google.. lol

TobiSGD 10-12-2011 11:28 AM
Open a terminal and enter the commands
Code:
sudo apt-get update
sudo apt-get install firmware-b43-lpphy-installer

wabbalee 10-13-2011 05:17 PM
DrArroganto, on a ubuntu (assuming it is Ubuntu, not Kubuntu) the package manager name is 'synaptic', sending 'links' so the other user clicks it and downloads it, is not how it works with a linux system.
so start this package manager and see what happens..
when it is finished doing its thing, at the bottom of its window you will see the number of the available packages (on mine 33000+ available and 2000+ installed)
once you are in there you do a 'search' (read: not 'quick search') for 'b43' and see what it comes up with, from there, see if it makes any sense at all and tell us what you think.

good luck..
