Wireless connection not working in Ubuntu 10.10

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.

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|prism|rtl|rt2|rt3|usb|witch|wl'; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo lsmod; cat /var/lib/NetworkManager/NetworkManager.state; sudo /etc/init.d/networking restart

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

Having done as requested, and rebooted, the problem remains. And
curiously, the mini-window showing my connection has a yellow padlock
next to it. I haven't installed any security keys, so I'm wondering what
this signifies....it may be the problem?

Cheers,

I have installed a dual boot system with Windows 7. Wireless connection
works fine with Windows. Reinstalled Ubuntu 10.10, but wireless
connection still not working. On startup, a window advised me to
download Broadcome 43xx, as per usual. On attempting this, I received
the following error message: "Broadcom BCM4312 802.11b/g LD PHY device
not ready (firmware missing)". I checked in Synaptic Packages and found
Broadcom 43 cutter installed! So what gives? This is maddening. Tomorrow
I go back to Ubuntu 9.10. Meanwhile, I'm using a Netgear USB wireless
modem with 10.10 AND IT WORKS FINE!!!

Yours in frustration,
wordsmyth

If you go visit the following URL using Firefox or Chromium

https://answers.launchpad.net/ubuntu/+source/gnome-nettool/+question/131780

you will see that attachments do not work on answers.launchpad.net

So you did not send us the terminal output...

Anyway, the error "Broadcom BCM4312 802.11b/g LD PHY device
not ready (firmware missing)" means that the b43-fwcutter package does not support the BCM4312 wireless chipset. The bcmwl-kernel-source package is the RIGHT driver for the BCM4312 chipset.

You need to install the following Broadcom driver package using aptitude or Synaptic package manager: bcmwl-kernel-source

This will of course require a working wirED Internet connection in Ubuntu. (wired, not wireless)

For example: using the Terminal, you need to run the following commands to install bcmwl-kernel-source:

sudo aptitude update
sudo aptitude install bcmwl-kernel-source

Then reboot and retest wireless using Network Manager.

A similar explanation can be found at the end of this thread:

Hi Mark:

Thanks for your prompt response. Have done as you suggested and my
wireless connection now works fine! Many, many thanks!!!
