Ubuntu wireless Internet access solution

It was hard to install Oracle 11g on Ubuntu, and a new problem was found. 11.04 is good before, but 10.04 cannot be wireless. Now the problem has finally been solved. Let's take a look at my solutions.

Using the command lspci on the terminal will display information that your computer is connected to all PCI devices. To display only the Broadcom (including the WiFi card) manufacturing device, apply to "14e4" as follows: a filter.

Step 2.

Open the Application> attachment> terminal under the desktop menu in a terminal window, and enter the following command:

Lspci-vvnn | grep 14e4

Result:

[14e4: 432b]

. 0 Network controller [0280]: Broadcom Corporation BCM4322 802.11a/B/g/n Wireless LAN Controller [14e4: 432b] (rev 01

• Card/model-BCM4322
• The 432B in pci id-[14e4: 432B] is the wireless network device model.

Run the following command:

~ $ Sudo apt-get update

~ $ Sudo apt-get install bcmwl-kernel-source

Update the system and add another source

~ $ Sudo modprobe-r b43 ssb wl

~ $ Sudo modprobe wl

Install driver

Finally, restart the computer.

Turn the wireless switch on and off several times. Wait a moment to see the wireless network.
