Wireless not working in Ubuntu 10.10

I do have the same problem on HP mini 210 with Broadcom 4312 chipset. After upgrading to 10.10 my wifi does not work anymore.

The wifi indicator turn on when in boot process, but when login session, it goes off.

From terminal, I type :

cat /var/lib/NetworkManager/NetworkManager.state

and the result:

[main]
NetworkingEnabled=true
WirelessEnabled=false
WWANEnabled=false

edit it and make it true, but after reboot, it becomes false again.

If I type rfkill unblock wifi, it brings both bluetooth and wifi up. but when I press the wifi button, all gone and can not up anymore.

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.

Regards,

Mark

Hi Mark

Just before I was going to follow the instructions you gave I rebooted my laptop. For some or other unexplained, odd and/or weird reason the wireless is now fully functional.

I am totally stumped as to what could've caused this to happen.
So this question has a solution and an answer, but I don't know what it is LOL.

Thanks anyway

Regards
Tanya

Hi Mark,
This is the result:
