Gentoo, wireless network card Installation

A few days ago, my colleague introduced Gentoo Linux and was immediately attracted by it.

Compile from the day before yesterday (Friday) Evening. Because you are not familiar with the kernel options, use the genkernel and compile kde4.3.1 ......
After about ten hours, you can enter the system, but the wireless network card cannot be used. So it took a long time to explore, but it was not difficult ,......, If you only have 300 holes in a box, you can only put one finger in each hole ......

Well, let's get started. This article describes how to install a wireless NIC Driver. In fact, Wireless Configuration is more confusing. Next articleArticle.

Step 1: Set the kernel

In the original article of foreigners, the kernel is configured as follows:

Networking -- >
< M > Generic IEEE 802.11 Networking stack
[ * ] Enable full debugging output
< M > IEEE 802.11 WEP encryption ( 802 . 1X)
< M > IEEE 802 . 11i CCMP support
< M > IEEE 802 . 11i TKIP Encryption
< M > Software Mac add - On to the IEEE 802.11 Networking stack
[ * ] Enable full debugging output
 
Device Drivers -- > Network device support --> Wireless LAN drivers (non-hamradio) & wireless extensions
< M > Broadcom bcm43xx wireless support
[ * ] Broadcom bcm43xx debugging (recommended)
 

If you use another type of network card, you can do your homework on Google first.

Step 2 emerge bcm43xx-fwcutter
This step is mainly used to install the tool used to generate the kernel mod. Different NICs should be different.

Step 3: download firmware and install

My Nic is bcm4311, which is here: http://linuxwireless.org/en/users/Drivers/bcm43xx

Wget HTTP :// Bu3sch . De / B43 / Fwcutter / B43 - Fwcutter - 012 . Tar . Bz2
Tar xjf b43 - Fwcutter - 012 . Tar . Bz2
CD b43 - Fwcutter - 012
Make
CD ..
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 Http://www.cnblogs.com/ B43 - Fwcutter - 012 / B43 - Fwcutter - W " $ Firmware_install_dir " Wl_apsta_mimo . O

Step 4: load the kernel mod

Note: The names of Different kernel loads are different, which can be found.
How to check: dmesg | grep firmware

Localhost ZYF # Dmesg | grep firmware
Broadcom 43xx driver loaded [features : Pmlr , Firmware - ID : Fw13]

Then load it!

Modprobe fw13

OK, it should be recognized without restarting. However, the more difficult battle is the configuration of the wireless network card ...... Next article: Gentoo, wireless network configuration
