Will install it. I don't get how installing wireless "Should be the easiest part". Surely installing the base OS should be easiest of all. And Ubuntu does that

I already tried that, it didn't work. It downloaded what I was suppose to download but I always got an error message when I tried enbaling internet. Sorry about spelling.

Can you give the output of:

sudo rfkill list

Thanks

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 lsmod. 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.

Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

sudo apt-get update; sudo apt-get install hwinfo grep; sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | egrep 'acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|ndiswrapper|NPE|ound|p54|prism|rtl|rt2|rt3|usb|witch|wl'; iwconfig; cat /etc/modprobe.d/* | egrep 'acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|witch|wl'; sudo hwinfo --netcard ; cat /var/lib/NetworkManager/NetworkManager.state; sudo lsmod

Step 3: Please post results (copy/paste terminal output) on this thread. The troubleshooters here need to see the full Terminal output from running the above command.

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

Regards,

Mark

To answer the question that you sent to me personally:

Q: "I'm going to do the steps you told me to do, but will I need the full
version of ubuntu to actually complete it, because I'm currently using
the trial."

A: There is no such thing as a trial version and a full version of Ubuntu. Every "desktop" installation CD of Ubuntu is both a LiveCD (for testing Ubuntu BEFORE installing) and an installation CD at the same time (except if you chose the alternate install cd image).

If you boot into an Ubuntu LiveCD session (WITHOUT installing to harddisk), then you can successfully test certain, but NOT all wireless chipsets. For example: you cannot test the BCM4312 wireless chipset during the LiveCD session, because most Broadcom chipsets require proprietary firmware that are NOT allowed to be provided as part of the Ubuntu Live/Install CD. You need a working, wired Internet connection to download and install the Broadcom firmware to the harddisk. Then you need to REBOOT before you can use the newly downloaded firmware.

If you reboot after a LiveCD session, Ubuntu will simply forget about the firmware download and boot Ubuntu from the CD in a clean state again. So Broadcom chipsets will not work out-of-the-box during LiveCD sessions.

So you need to first install Ubuntu to the harddisk and then install certain firmware, before you can test Broadcom wireless chipsets.

I currently have windows xp and I plan on switching to ubuntu 10.10, but I wanted to test it out first. If I dual boot windows xp and ubuntu 10.10, how can I remove windows xp afterwards if it works. Also, are you sure it will work?

Thanks!

I recommend making a backup of all your personal data to an offline storage medium BEFORE installing Ubuntu to the harddisk.

I am pretty certain we can get your BCM4312 802.11b/g LP-PHY wireless chipset working, AFTER you have installed Ubuntu to the harddisk.

You can always reformat your Windows partition using Ubuntu's partition manager application(s) (for example: using gparted) and use it as an ext4 filesystem, effectively deleting Windows and all applications on the Windows partition.
