centos安装ax200驱动

<p>如果内核低于5.1需要安装一下内核<br><em>rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org</em><br><em>rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm</em><br><em>yum --enablerepo=elrepo-kernel install kernel-ml -y</em></p>
<p><em>sed -i "10s/^.*/default=0/" /boot/grub/grub.conf</em><br><em>egrep ^menuentry /etc/grub2.cfg | cut -f 2 -d \'</em><br><em>grub2-set-default 0</em></p>
<p><em>reboot</em></p>
<p>&nbsp;</p>
<p>&nbsp;</p>
<p>Cnetos 7 Intel® Wi-Fi 6 AX200 160MHz 驱动安装示例：</p>
<p>wget https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi/iwlwifi-cc-46.3cfab8da.0.tgz</p>
<p>tar xzf iwlwifi-cc-46.3cfab8da.0.tgz</p>
<p>cp iwlwifi-cc-46.3cfab8da.0/*&nbsp;/lib/firmware</p>
<p>&nbsp;</p>
<p>然后重启系统。</p>
<p>&nbsp;</p>
<p>&nbsp;</p>
<p>&nbsp;</p>
<p>&nbsp;</p>
<p><strong>离线升级内核方法</strong></p>
<p>1、下线内核&nbsp;</p>
<p>https://elrepo.org/linux/kernel/el7/x86_64/RPMS/</p>
<p>&nbsp;</p>
<p>如ml版本</p>
<p>下载指定版本 kernel&nbsp; &nbsp; &nbsp;&nbsp;kernel-ml-5.11.6-1.el7.elrepo.x86_64.rpm</p>
<p>下载指定版本 kernel-devel&nbsp; &nbsp;kernel-ml-devel-5.11.6-1.el7.elrepo.x86_64.rpm</p>
<p>&nbsp;</p>
<p>2、将2个rpm文件拷贝到目标机器任意目录，然后安装<br>yum -y install&nbsp;kernel-ml-devel-5.11.6-1.el7.elrepo.x86_64.rpm<br>yum -y install&nbsp;kernel-ml-5.11.6-1.el7.elrepo.x86_64.rpm</p>
<p>&nbsp;</p>
<p>3、通过以下命令查看内核顺序<br>awk -F\' '$1=="menuentry " {print $2}' /etc/grub2.cfg</p>
<p>&nbsp;</p>
<p>此时5.11.6的位置为0<br>CentOS Linux (5.11.6-1.el7.elrepo.x86_64) 7 (Core)</p>
<p>CentOS Linux (3.10.0-957.el7.x86_64) 7 (Core) </p>
<p>CentOS Linux (0-rescue-780c70defb4a40f996ab04470668ca42) 7 (Core)&nbsp;</p>
<p>&nbsp;</p>
<p>4、想生效最新的内核，还需要修改内核的启动顺序为0：<br>vim /etc/default/grub<br>或</p>
<p><em>grub2-set-default 0</em></p>
<p>&nbsp;</p>
<p>5、接着运行grub2-mkconfig命令来重新创建内核配置<br>grub2-mkconfig -o /boot/grub2/grub.cfg</p>
<p>&nbsp;</p>
<p>6、重启reboot</p>
<p>&nbsp;</p>
