I have a HP Pavilion G7 Notebook computer and when I use ubuntu it starts up fine, and then when I get in I can't connect to wifi. I know the problem because it says something like "disconnected by hardware switch." I tried to turn on my hardware switch but it doesn't want to turn on (it is a button that is supposed to shine a blue light to show that it is on, but it shines a orange light which means it is off).

You can try using the following command in terminal; rfkill unblock wifi. After that turn off your wifi switch and then back on. If that doesn't work, go to the network setting in the upper right corner of your screen with the notification icons. unenable the networking and do the command "rfkill unblock wifi", after that renable the networking.

Sir try following this link. Your Wifi has probably been blacklisted by Ubuntu. I am not sure why they allow this, but they have given us the solution. See here for more details.

my track in the woods as follows....

Installing Broadcom Wireless Drivers
How to Install Broadcom / STA Wireless card (BCM43XX)

up vote 7 down vote favorite

I'm having serious problems installing the Broadcom drivers for Ubuntu. It worked perfectly on my previous version, but now, it is impossible. I'm a user with no advance knowledge in Linux, so I would need clear explanations on make, compile, etc. I was following the instructions on the following blog, with no luck.
How can I get Broadcom BCM4311 Wireless working?
Can someone help me?
Edit: For the command: lspci | grep Network, I get the following message:

06:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)

For the command: iwconfig, i get the following:

lo no wireless extensions. eth0 no wireless extensions.

When i follow the following steps (from the above link), there are a NO error message at all:
1. Open the 'Ubuntu Software Centre' and search for bcm
2. Uninstall the bcm-kernel-source package
3. Make sure that the firmware-b43-installer and the b43-fwcutter packages are installed

Then, type into terminal:

cat /etc/modprobe.d/* | egrep '8180|acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|witch|wl'

(you may want to copy this) and see if the term blacklist bcm43xx is there
if it is, type

cd /etc/modprobe.d/ and then sudo gedit blacklist.conf

put a # in front of the line: blacklist bcm43xx
then save the file (I was getting error messages in the terminal about not being able to save, but it actually did save properly).
reboot 'End of procedure'
Before (not Ubuntu 11.04), if I wanted to connect wireless, I just went to the icon at the upper side of the screen, click, showed ALL the wireless network available, and done.
