Ubuntu Wireless Network Configuration

The wireless network is surging, And it is filled with the world of network technology. The configuration problems in linux are also naturally formed. Here we will introduce the wireless network configuration of ubuntu.

My website is HP au3145. AMD64cpu, 2 GB memory, 80 GB hard disk, wireless network card boardcom chip.

I am almost desperate, but I still cannot accept this reality. I will check the information online. Of course, it is about boardcom setting in ubuntu)

I don't want to see the results. Then try it.

First, enter the following command in the ubuntu terminal.

Sudo modprobe-r bcmwl5
Sudo rmmod ndiswrapper
Sudo apt-get remove ndiswrapper-utils
Sudo rm-r/etc/ndiswrapper/
Sudo rm-r/etc/modprobe. d/ndiswrapper
Some of the above steps may report errors.

Copy the bcmw15.inf and bcmw15.sys files to your desktop. These two files are files in the windows Wireless Driver and find them)
Follow the prompts below to get the relevant knowledge. Open a terminal process and enter the following command. Note that your network connection is enabled. Now that you can access a wireless network, you have to have a wireless network

The command is as follows:
Sudo apt-get install ndiswrapper-utils
Sudo ndiswrapper-I ~ /Desktop/bcmwl5.inf
Sudo ndiswrapper-m
For conffile in/etc/ndiswrapper/bcmwl5/*. conf; do
Sudo cat $ conffile | sed-e's/RadioState | 1/RadioState | 0/'> $ conffile
Done

Restart your computer.
When you restart your wireless network card, the light should be on. If not, enter the following command:
Sudo modprobe ndiswrapper
Now your wireless network card is enabled. Open your network setup tool-> System Management-> Network
Select your wireless network card, which may be wlan0) and click Properties to press the button.
Select this device), and enter your network name and connection settings. If you do not know, you can ask your office network administrator or copy your settings in windows and enter your WEP code carefully if you are using it. You should input it in hexadecimal format. If you do not convert it, add "s" before your code:
Click OK. The window should be closed soon. If it gets stuck, you may not be connected. Return to the network settings window, select your wireless network card as the default gateway device, and click "OK" again, the window should soon be closed to enjoy the wireless paradise. If everything goes well, you can delete the two files on the desktop.

You may find some problems with the signal strength program. This is a known bug. If you have a problem, try to access your windows -- if you have a dual system -- and check whether your card is activated. Some laptops can use special key combinations to disable wireless NICs. I have not found a reliable method in linux.
Sudo apt-get install b43-fwcutter is this step for my wireless device to install the driver)
