I'm using Natty.

I have a wifi card (as obtained from the command lspci -v | less)-


03:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)
Subsystem: Broadcom Corporation Device 0465
Flags: bus master, fast devsel, latency 0, IRQ 10
Memory at b4000000 (32-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel modules: ssbI also have the following packages installed:
1. bcmwl-kernel-source
2. broadcom-sta-common
3. broadcom-sta-source

Also, my laptop Lenovo 3000-Y500, has
1. a manual wifi switch (which glows properly in Windows, but not in Ubuntu) and also
2. has a keyboard shortcut to enable/disable wifi (the keyboard shortcut works by pressing the Fn key + F4 key)

The output of lspci -vnn | grep 14e4 -


03:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01)
Subsystem: Broadcom Corporation Device [14e4:0465]
Even after all this, ubuntu does not detect any wifi networks. Wifi-radar also does not detect my wifi card. what should I do?

Hey there!

I've got the same card!

I haven't yet managed to install a working driver other than ndiswrapper on Ubuntu from 10.04 to 11.04.

If you want to try ndiswrapper, keep reading:
Run in terminal:


sudo rmmod b43
sudo rmmod ssb
sudo rmmod wlto remove conflicting modules

Then do a back-up:


sudo cp /boot/initrd.img-`uname -r` /path/to/somewheresafeAnd finally update initrd.img:


sudo update-initramfs -uThen install the driver using ndiswrapper (package is called ndis-gtk)


sudo apt-get install ndis-gtk ndiswrapperDriver:

(Be sure to unpack it first ;p )

Then add "ndiswrapper" (without quotation marks) to /etc/modules:


gksu gedit /etc/modules
Ta-dah! You should have WiFi working! :p

thank you!!

this got my Acer Aspire 3680-2472 working when the STA driver that ubuntu automatically installed and the OEM Windows Vista Broadcomm driver from Acer did not.
