问题列表
1 默认内核版本3.10.0-693.el7.x86_64没有加载该款硬件的驱动,需要下载驱动源码
2 源码下载后编译出错,需要更新内核源码的头文件
3 NetworkManager无法进行WIFI扫描,因为加载的驱动被识别为有线,dev name is enp0s* but not wlp0s*
4 修改为驱动源码,识别为设备名为wlp0s*后,依然出现iw wlp0s20f0u8 info返回command failed: No such device (-19),
暂时没解决问题,参见问题5,但是都可以通过命令行连接成功
5 更新到最新的内核4.163.3版本后依然在NetworkManager界面认证过程失败,因为IPV6被设置为disabled
问题 1
源码下载地址
编译时需要确保安装了kernel-headers-*包
[root@localhost ~]# rpm -qa "kernel*"
kernel-tools-3.10.0-693.21.1.el7.x86_64
kernel-3.10.0-693.el7.x86_64
kernel-3.10.0-693.21.1.el7.x86_64
kernel-headers-3.10.0-693.21.1.el7.x86_64
kernel-devel-3.10.0-693.el7.x86_64
kernel-ml-devel-4.16.3-1.el7.elrepo.x86_64
kernel-tools-libs-3.10.0-693.21.1.el7.x86_64
kernel-ml-4.16.3-1.el7.elrepo.x86_64
dkms add .
dkms install rtl8192eu/1.0 #增加一个驱动模块且不随内核版本更新的影响
dkms status
dkms remove -m rtl8192eu -v 1.0 --all
问题 2
编译出现IEEE80211_BAND_2GHZ未定义错误时需要修改 /usr/src/kernels/3.10.0-693.el7.x86_64/include/net/cfg80211.h 增加如下枚举
enum ieee80211_band {
IEEE80211_BAND_2GHZ = NL80211_BAND_2GHZ,
IEEE80211_BAND_5GHZ = NL80211_BAND_5GHZ,
IEEE80211_BAND_60GHZ = NL80211_BAND_60GHZ,
/* keep last */
IEEE80211_NUM_BANDS
};
编译成功后加载驱动,通过命令行设置参数可以连接热点成功

问题 5
参考 解决,详细过程如下:
升级到epel的最新内核参考 https://www.cnblogs.com/zengkefu/p/5667145.html,升级后在启动时可以选择启用最新版本的内核4.16.3-1.el7.elrepo.x86_64,此版本已经包含了rtl8192edu的驱动和固件。
-
1、导入key
-
rpm --import
-
当然,如果已经修改了repo的gpgcheck=0也可以不导入key
-
2、安装elrepo的yum源
-
rpm -Uvh
-
3、安装内核
-
在yum的ELRepo源中,有mainline颁布的,可以这样安装:
-
yum --enablerepo=elrepo-kernel install kernel-ml-devel kernel-ml -y
-
当然也可以安装long term的:
-
yum --enablerepo=elrepo-kernel install kernel-lt -y
-
[root@localhost ~]# uname -a
-
Linux localhost.localdomain 4.16.3-1.el7.elrepo.x86_64 #1 SMP Thu Apr 19 08:21:26 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux
可以直接通过NetworkManager进行扫描和连接,连接过程一直连接不上,以为是NetworkManager在Scan热点时设置为动态WIFI 动态MAC原因,通过设置NetworkManager.conf文件后还是出错
参考文档

https://developer.gnome.org/NetworkManager/stable/NetworkManager.conf.html#id-1.2.5.12
-
[root@localhost ~]# cat /etc/NetworkManager/NetworkManager.conf |grep -v "^#"|grep -v "^$"

-

-
再搜索到,提示可能是两端的IPV6不匹配,刚好我的机器通过grub强制关闭了IPV6
-
[root@localhost ~]# cat /etc/default/grub
-
GRUB_TIMEOUT=2
-
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
-
GRUB_DEFAULT=0
-
GRUB_DISABLE_SUBMENU=true
-

-

-
GRUB_DISABLE_RECOVERY="true"
-
取消后就可以连接成功了
