After several days of hard work, I finally installed the Ubuntu wireless network card and found a lot of methods on the Internet, but none of them were successful. It seems that I could not execute them all, it may be useful to write out my installation process.
Environment: compaq515 notebook
Wireless network adapter type: Broadcom Corporation bcm4312 802.11b/g (Ubuntu command: lspci-vnn | grep 14e4)
Installation Process reference site: http://linuxwireless.org/en/users/Drivers/b43#Known_PCI_devices
Installation conditions: the laptop must be connected to the Internet (wired NICs are generally built-in drivers)
Installation Process:
1. view the NIC type: lspci-vnn | grep 14e4. Check whether the NIC type is broadcom43xx.
2. Check the Ubuntu kernel version: uname-A. My version is Linux Ubuntu 2.6.35-22-generic.
3. Install b43-fwcutter: Install b43-fwcutter

Write wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-013.tar.bz2
Tar xjf b43-fwcutter-013.tar.bz2
CD b43-fwcutter-013
Make
CD ..
Note: This step should remember the b43-fwcutter installation path, which will be used below.
4. Select the driver version based on the kernel version:
Note: The following installation path must be executed under/lib/firmware:
A. If your version is a linux-2.6.24, execute:
Export firmware_install_dir = "/lib/firmware"
Wget http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2
Tar xjf broadcom-wl-4.80.53.0.tar.bz2
CD broadcom-wl-4.80.53.0/kmod
Sudo.../b43-fwcutter-013/b43-fwcutter-W "$ firmware_install_dir" wl_apsta.o
B. If your version is linux-2.6.25 or higher, run: (my version is here)
Export firmware_install_dir = "/lib/firmware"
Wget http://mirror2.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2
Tar xjf broadcom-wl-4.150.10.5.tar.bz2
CD broadcom-wl-4.150.10.5/driver
Sudo.../b43-fwcutter-013/b43-fwcutter-W "$ firmware_install_dir" wl_apsta_mimo.o
If the execution is successful, a lot of *. FW files will be parsed and no alarm information will be displayed. This is a success!
Note:.../b43-fwcutter-013, this place must choose your own installation path of the b43-fwcutter.
I hope this will be helpful to my friends who are new to Ubuntu after several days of hard work.
