Broadcom 4313 (rev 01) Issue

[ajukilibodin]

04:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

Hello, the built-in, driver that was there with Jockey doesn't work.

iwconfig

lo no wireless extensions.

wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=19 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off

eth0 no wireless extensions.

Yet it is unable to find any wireless networks.

modprobe b43 didn't work either.

In 11.10 and 11.04, I did http://www.broadcom.com/docs/linux_sta/README.txt this but it no longer works as I am unable to compile it. Tried both upgraded and a fresh installation of 12.04

I don't get why "make" doesn't work.

Wire works.

Thanks for your help in advance.

Hello, the built-in, driver that was there with Jockey doesn't work.

We suspect this is a fault in 12.04. There is a bug report in place and it's being addressed. Let's see what we need to do to get you going. It depends on the exact details of your card.Please post:

lspci -nn | grep 0280

We can fix this pretty quickly.

lspci -nn | grep 0280

04:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)

Thank you for helping!

[chili555]

Please try:

sudo apt-get install bcmwl-kernel-source

If it reports that the package is already installed, then:

sudo apt-get install --reinstall bcmwl-kernel-source

Now load the driver:

sudo modprobe wl

Any improvement? Note and post back any errors or warnings.

[ajukilibodin]

ReInstalls perfect. Yet Ubuntu still fails to recognize any wireless networks.

None of these drivers worked for me back in 11.10. I had to install the STA from the Broadcom website. It fails to "make" now.

No warnings no errors.

Please let us see:

modinfo wl | grep 4727

Thanks.

[ajukilibodin]

modinfo wl | grep 4727

Please do:

sudo modprobe wl
sudo iwlist eth1 scan  <--it may be wlan0
rfkill list all
dmesg | grep wl

[ajukilibodin]

ajukilibodin@Dream:~$ sudo modprobe wl

This just gets crazier by the second. No less than three drivers claim your device:

chili@LAPTOP60:~$ modinfo bcma | grep 4727
alias:          pci:v000014E4d00004727sv*sd*bc*sc*i*
chili@LAPTOP60:~$ modinfo brcmsmac | grep 4727
alias:          pci:v000014E4d00004727sv*sd*bc*sc*i*
chili@LAPTOP60:~$ modinfo wl | grep 4727
alias:          pci:v000014E4d00004727sv*sd*bc*sc*i*

Are the other two loaded?

lsmod | grep -e brc -e bcma

If so, we need to blacklist them:

sudo su
echo "blacklist bcma" >> /etc/modprobe.d/blacklist.conf
echo "blacklist brcmsmac" >> /etc/modprobe.d/blacklist.conf

Reboot and let us have your report.
