After upgrading Ubuntu 11.04, I still cannot find the wireless network and cannot work with the built-in driver. I have tried many methods to compile wl by myself, but still failed.

Solution

Add a "contrib" component/Etc/apt/sources. list, For example:

1. # Debian Squeeze/6.0
2. Deb http:// Ftp.us.debian.org/debian squeeze main contrib non-free

Update the list of available packages and install the wireless-tools package:

1. Sudo apt-get update
2. Sudo apt-get install wireless-tools

Install the appropriate firmware installer package:

For 802.11b/g devices with a bcm1_6 revision 3, BCM4311 or BCM4318 chipset, install firmware-b43-installer:

1. Sudo apt-get install firmware-b43-installer

For 802.11b/g devices with a BCM4312 LP-PHY chipset (PCI-ID 14E4: 4315), install firmware-b43-lpphy-installer:

1. Sudo apt-get install firmware-b43-lpphy-installer

The necessary kernel module shoshould be automatically loaded.

Of course you can load

Sudo modprobe b43

OK. The wireless network indicator is on, and the driver is installed successfully!

Note: If the wireless module is not automatically loaded upon startup, you can add it to the configuration file/etc/modules.
