Ubuntu 11.04 is installed on the hard disk, and the Broadcom 802.11 Wireless NIC driver is not installed.

The driver is actually in the ISO package. The only problem is to install the driver from the hard disk:

Read: http://www.linuxidc.com/Linux/2010-07/26952.htm

Step 1: mount the ISO file to a virtual optical drive-key! Otherwise, the system will prompt you to insert the installation disk.

All operations (including errors) are as follows)

Www.linuxidc.com @ linuxidc :~ $ Sudo rm-rf/dev/cdrom (incorrect operation. Do not imitate it !)

Www.linuxidc.com @ linuxidc :~ $ Sudo rm-rf/dev/cdrom
Www.linuxidc.com @ linuxidc :~ $ Sudo ln-s/dev/loop7/dev/cdrom
Www.linuxidc.com @ linuxidc :~ $ Sudo losetup/dev/loop7/media/cdimage/myfile. iso

// The directory does not exist?
Www.linuxidc.com @ linuxidc :~ $ Sudo mount/dev/cdrom/media/cdrom
Mount: mount point/media/cdrom does not exist

// Create one by yourself
Www.linuxidc.com @ linuxidc :~ $ Sudo mkdir/media/cdrom

// Mount successfully
Www.linuxidc.com @ linuxidc :~ $ Sudo mount/dev/cdrom/media/cdrom
Www.linuxidc.com @ linuxidc :~ $

Step 2: Find the deb installation package in the system installation package:

/Pool/restricted/B/bcmwl-kernel-source... (a long string)... ubuntu3_i386.deb

There is only this file in this directory. Should it be correct?

Step 3: Right-click and choose Ubuntu Software Center to open, install, and restart the system.
