安装与配置wpa_supplicant无线网络链接工具

Posted 2021-01-31 renren-study-notes

1.安装wireless

2.安装pciutils，运行命令查看无线网络设备硬件的名字

lspci

3.解压在编译lfs过程中用过的linux内核包，进入linux内核包按照lfs的linux内核编译方法编译内核加入以下配置

[*] Networking support  --->                              [CONFIG_NET]
  [*] Wireless  --->                                      [CONFIG_WIRELESS]
    <*/M> cfg80211 - wireless configuration API           [CONFIG_CFG80211]
    [*]     cfg80211 wireless extensions compatibility    [CONFIG_CFG80211_WEXT]
    <*/M> Generic IEEE 802.11 Networking Stack (mac80211) [CONFIG_MAC80211]
Device Drivers  --->
  [*] Network device support  --->                        [CONFIG_NETDEVICES]
    [*] Wireless LAN  --->                                [CONFIG_WLAN]

<*/M>一定要在所选择的项目上面打上m
我的机器是intel7625的无线网卡设备，wireless LAN下没有这个型号，查询manjaro给无线网卡加载的是哪个模块，所以选择了iwlwifi的两个模块

安装推荐依赖

libnl-3.4.0

暂不考虑安装桌面网络配置，运行安装命令行wifi链接工具

设置wpa

wpa_passphrase SSID SECRET_PASSWORD > /etc/sysconfig/wpa_supplicant-wifi0.conf

安装引导blfs-bootscripts-20180105脚本

make install-service-wpa

为dhcpcd创建

cat > /etc/sysconfig/ifconfig.wifi0 << "EOF"
ONBOOT="yes"
IFACE="wlan0"
SERVICE="wpa"

# Additional arguments to wpa_supplicant
WPA_ARGS=""

WPA_SERVICE="dhcpcd"
DHCP_START="-b -q <insert appropriate start options here>"
DHCP_STOP="-k <insert additional stop options here>"
EOF

链接无线接入点

ifup wifi0

 重启后会出现如下提示：

显示需要iwlwifi-7265D-22和29固件，去lfs的固件网站下载，放到/lib/firmware/目录下，重启机器就可以看到无线网卡模块已经自动加载了。
