14.运行命令查看无线网络设备硬件的名字
lspci
15.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添加以下配置
[*] 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，查询其它linux发行版给无线网卡加载的是哪个模块，所以选择了iwlwifi的两个模块

16.去lfs的固件网站下载所对应的iwlwifi-7265D-22到29区间的固件到/lib/firmware/目录下
cd /lib/firmware/ wget http://anduin.linuxfromscratch.org/BLFS/linux-firmware/iwlwifi-7265D-29.ucode
17.下载wpa包和补丁并校验md5
wget https://w1.fi/releases/wpa_supplicant-2.6.tar.gz
wget http://www.linuxfromscratch.org/patches/blfs/8.3/wpa_supplicant-2.6-upstream_fixes-2.patch
md5sum -c md5sums
18.解压并进入wpa包目录
tar -xvf wpa_supplicant-2.6.tar.gz
cd wpa_supplicant-2.6
19.参照书中内容编译安装
cat > wpa_supplicant/.config << "EOF" CONFIG_BACKEND=file CONFIG_CTRL_IFACE=y CONFIG_DEBUG_FILE=y CONFIG_DEBUG_SYSLOG=y CONFIG_DEBUG_SYSLOG_FACILITY=LOG_DAEMON CONFIG_DRIVER_NL80211=y CONFIG_DRIVER_WEXT=y CONFIG_DRIVER_WIRED=y CONFIG_EAP_GTC=y CONFIG_EAP_LEAP=y CONFIG_EAP_MD5=y CONFIG_EAP_MSCHAPV2=y CONFIG_EAP_OTP=y CONFIG_EAP_PEAP=y CONFIG_EAP_TLS=y CONFIG_EAP_TTLS=y CONFIG_IEEE8021X_EAPOL=y CONFIG_IPV6=y CONFIG_LIBNL32=y CONFIG_PEERKEY=y CONFIG_PKCS12=y CONFIG_READLINE=y CONFIG_SMARTCARD=y CONFIG_WPS=y CFLAGS += -I/usr/include/libnl3 EOF
patch -p1 -i ../wpa_supplicant-2.6-upstream_fixes-2.patch &&
cd wpa_supplicant &&
make BINDIR=/sbin LIBDIR=/lib
install -v -m755 wpa_{cli,passphrase,supplicant} /sbin/ &&
install -v -m644 doc/docbook/wpa_supplicant.conf.5 /usr/share/man/man5/ &&
install -v -m644 doc/docbook/wpa_{cli,passphrase,supplicant}.8 /usr/share/man/man8/
20.安装systemd支持
install -v -m644 systemd/*.service /lib/systemd/system/
21.安装dbus支持
install -v -m644 dbus/fi.{epitest.hostap.WPASupplicant,w1.wpa_supplicant1}.service \ /usr/share/dbus-1/system-services/ && install -v -d -m755 /etc/dbus-1/system.d && install -v -m644 dbus/dbus-wpa_supplicant.conf \ /etc/dbus-1/system.d/wpa_supplicant.conf
22.配置开机启动wpa服务支持
systemctl enable wpa_supplicant
23.返回blfs-sources目录并删除解压的包目录
cd $LFS/sources/blfs-sources rm -rf wpa_supplicant-2.6
24.设置wpa
install -v -dm755 /etc/wpa_supplicant && wpa_passphraseSSIDSECRET_PASSWORD> /etc/wpa_supplicant/wpa_supplicant-wifi0.conf
wifi0替换为pci查到的无线网络设备名字
25.配置开机启动wpa网卡服务
systemctl enable wpa_supplicant@wlan0
wlan0更换为无线设备名字
26.使用wpa_cli遇到如下报错
Could not connect to wpa_supplicant: (nil) - re-trying
则在/etc/wpa_supplicant/wpa_supplicant-wifi0.conf文件中加入以下参数
ctrl_interface=DIR=/run/wpa_supplicant GROUP=root
update_config=1
27.使用wps_cli工具链接无线网络的方法
1.进入wpa_cli工具下
wpa_cli
2.添加一个网络连接
add_network
默认id为0
3.扫描并显示结果
scan scan_result
4.设置网络id：0的接入点与连接秘钥
set_network 0 ssid “<填入网络名字>”
set_network 0 psk "<填入网络密码>"
5.使用配置网络或连接配置网络id 0
enable_network 0 select_network 0
