Centos wireless Nic settings

Lenovo ThinkPad e430. After centos is installed, the wireless network card has been unable to be used. It has gone through two twists and turns to the installation process of the network card driver. It took two nights to finally enjoy using the wireless network card.

1. view the specific model of the wireless network card

[[Email protected] local] # lspci

. 0 network controller: RealTek semiconduco., Ltd. rtl8188ce 802.11b/G/n WiFi adapter (Rev 01)

The driver is rtl8188ce.

Or

[[Email protected] local] # lspci | grep Network

. 0 network controller: RealTek semiconduco., Ltd. rtl8188ce 802.11b/G/n WiFi adapter (Rev 01)

Compared with the second one, it is easier to find. Directly, lspci lists all PCI devices, which is difficult to find.

2. Download

Download the corresponding version. I use 64-bit. I am optimistic about the version from the kernel. Then select the appropriate version to download the driver to the local device.

3. Prepare the installation package

[[Email protected] mayfio] # Yum install kernel-headers kernel-devel gcc

4. Installation

[[Email protected] rtl8192ce_linux_2.6.0006.0321.2011] # Make

If the following error is prompted

Make: ***/lib/modules/2.6.32-358. el6.x86 _ 64/Build: the file or directory does not exist. Stop.

Make: *** [all] Error 2

Solution

[[Email protected] 2.6.32-358. el6.x86 _ 64] # rm build-RF

[[Email protected] 2.6.32-358. el6.x86 _ 64] # ln-S/usr/src/kernels/2.6.32-358.6.1.el6.x86 _ 64/build

Then proceed with make.

[[Email protected] mayfio] # Make

Make [1]: Leaving directory '/usr/src/kernels/2.6.32-358.6.1.el6.x86 _ 64 ′

Then

# Reboot

After the system is restarted, you can see the wireless network card.
