broadcom sta problems please help!!!!!!!!!!!!!!!!!

**SCOOT1986** · December 31st, 2010

hey guys, im still pretty new to linux so bare with me. I recently upgraded to meerkat (10.10) and im having issues with my wireless connection. It will drop connection randomly.

pci- netgear wn311b-100nas wpa security
broadcom sta prop. driver
wicd is installed

i'm only posting this because i've tried everything i can think of and i've spent HOURS on google and here trying to figure this out.

i will post iwconfig and ifconfig results when i get a chance later 2nite. if you guys have any idea or know how to fix it, it would be very much appreciated

Hi SCOOT1986! Running those commands well help us a lot.

Please also run:

Code:

lspci -v

That will help us verify whether the Broadcom STA driver is installed properly.

in the process of running this through terminal it's dropped the connection about 6 times and wicd popped up and error stating "bad password" could this all be a conflict with the wireless security??

**PatchesTheCaveman** · January 1st, 2011

I have a BCM4312 using the STA driver that works great with a WPA2 encrypted router so I don't think so.

The output from iwconfig indicates while your wireless signal isn't great, it should be more than adequate.

Have you tried using NetworkManager instead of wicd?

Code:

sudo apt-get remove wicd
sudo apt-get install network-manager

Usually we have people go the other way around, but there's a first time for everything!

I'm a little confused as to why it would disable itself??

**PatchesTheCaveman** · January 1st, 2011

It could just do that when it's not being used. Then again, it could indicate a problem. Run this command and copy/paste the results:

Code:

dmesg | grep -i wl

That will show any errors the STA driver might be experiencing.

I'll check right now and see if I can replicate that lshw behavior on my system.

**PatchesTheCaveman** · January 1st, 2011

I manually disconnected from my wireless network and lshw still did not report my Broadcom device as DISABLED so something funky is definitely going on here.

**PatchesTheCaveman** · January 1st, 2011

There are updated drivers from Broadcom that might help your situation.

Visit http://www.broadcom.com/support/802.11/linux_sta.php to download. Follow the instructions in the README.txt file to install. Let me know if you run into trouble.

While the README states that you can get them prepackaged from Ubuntu (and you can), Ubuntu's version is outdated.

**SCOOT1986** · January 1st, 2011

thanks! ive gone through and downloaded the build tools required, and double checked that everything was installed correctly, downloaded the new .gz file. but im not sure how to "build" the module.

BUILD INSTRUCTIONS
------------------
1. Setup the directory by untarring the proper tarball:

For 32 bit: hybrid-portsrc_x86-32_v5.100.82.38.tar.gz
For 64 bit: hybrid-portsrc_x86-64_v5.100.82.38.tar.gz

Example:
# mkdir hybrid_wl
# cd hybrid_wl
# tar xzf <path>/hybrid-portsrc_x86-32_v5.100.82.38.tar.gz <------stuck

2. Build the driver as a Linux loadable kernel module (LKM):

# make clean (optional)
# make
