I have a Dell Vostro 3300 which I use as a dual-boot. All the LEDs work perfectly fine on Windows 7 but the Wi-Fi LED does not work on Ubuntu 11.10. There is a Bluetooth LED which works perfectly fine.

I tried installing the proprietary Broadcom wireless driver, it did not help either.

Vostro-3300:~$ lspci -vnn | grep 14e4 12:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01) 

and the second output is :

lsmod | grep brcmsmac 
brcmsmac 631693 0 brcmutil 17837 1 brcmsmac mac80211 310872 1 brcmsmac cfg80211 199587 2 brcmsmac,mac80211 crc_ccitt 12667 1 brcmsmac

Any ideas?

Can you paste the output of lspci -vnn | grep 14e4 and lsmod | grep brcmsmac ? –  sagarchalise Nov 4 '11 at 11:14

Its in the todo list but not yet supported for the driver you are using.

BCM 4313 card uses the opensource broadcom driver called brcmsmac and not the proprietary driver wl. If you want to light-up the Led you need to blacklist brcmsmac and in some cases bcma as well and use proprietary driver. So what you may need is:

Temporarily

sudo rmmod brcmsmac
sudo rmmod bcma
sudo modprobe wl

Permanently

In /etc/modprobe/blacklist-b43.conf add blacklist brcmsmac blacklist brcmfmac blacklist bcma

I had to remove bcma module as well but it may not be the case with every card. But I had performance issues with the wl driver especially with powersave mode so I avoided installing it and use the kernel provided driver.

thank you so much! i am using it now. let me see how well the new driver fares. if it isnt that good, will revert back to good old opensource :). thanks again –  Ubuntuser Nov 8 '11 at 10:19
