Bcm4727

**kurci2** · January 12th, 2012

HI!
I have a strange problem. On my laptop i have bcm4727 wireless card. I use Microsoft Windows 7 (photo editing, video editing) and Ubuntu 11.10 i386.
I have wireless connection at home. When i am connected with Windows everything works well, but when i am connected with Ubuntu connection is not well. I am connected all the time but the connection does not work.
When i try to open a web page google chrome just stays at "Sending request..."
It is the same wheather if a have BCM driver installed or not.
Does anybody know what could be wrong. Am i missing something or maybe i need an additional package installed?

Thanks!

When it boots and no networks are showing, please see if the module wl is loaded. Please open a terminal and run:

Code:

lsmod | grep wl

If it is not loaded, meaning the terminal command comes back blank, load it:

Code:

sudo modprobe wl

Now does your wireless work?

If not then please post the output of this

Code:

sudo lshw -C network

Moved to the network forum.

Have you plugged in an ethernet cable and gotten updates? That may install appropriate firmware and drivers. Even though you have a driver loaded the firmware is required. Most Broadcom cards work 'out of the box' nowadays but you need to get online with a cable first.

i think that you did not quiet understand my problem.
I DO HAVE WIRELESS working, but when i am connected in windows everything is good
but when i am connected (CONNECTION IS ESTABLISHED) i can not get internet access ... google chrome just says Sending request... thet is neaver send...

it is really strange! In fact sometimes internet actually works for a couple of minutes and after that internet access is gone...
there is one thing more...connestion strengh in low (but on windows everything is ok)

but if you really want... Note: i am writing this form linux in those minutes when i have internet access without my bcm drivers installed

Hi, you do have driver installed for wireless it shows up in the information you posted, I suspect that the wl driver is a better choice for your device but your card is tricky with 11.10.

Please post the output of:

Code:

lspci -nnk | grep -iA2 net
lsmod
rfkill list all
nm-tool
sudo iwlist scan

here by clicking on new reply and click # and paste the information between the brackets.
Thank you

firstly, thanks for your reply.
i would really appreciate if you could tell my how to install wl diver ... if it is necessary

Hi, we are going to take this one step at a time please do:

Code:

echo "blacklist bcma" | sudo tee -a /etc/modprobe.d/blacklist.conf

Reboot with wired connection unplugged.

Which network are you trying to connect too?
Thanks

Hi, even with security turned off you still can not connect with your wireless right?

Are you connected by a wired connection that is what I was saying to unplug.
Thanks
