Other-install-wifi-AX211-driver

发表于 更新于 分类于 Waline：

问题现象：

在给Legion Y7000P IAH7联想电脑本来带的win11系统再加装一个CentOS-7-x86_64-Minimal-2009.iso的时候发现没有wifi驱动，无法连接网络，切换装ubuntu系统，也是没有wifi驱动。

尝试解决：

  1. 下载英特尔® Wi-Fi 6 AX210 160MHz驱动**(改驱动不起作用)**

    本来电脑是AX211驱动，但是官网没有211的Linux驱动，但是在官网发现AX211驱动和AX210的驱动在win11系统下是一样的，因此尝试用210的Linux驱动安装。

  2. 根据AX210的Linux驱动要求内核5.10+，因此先升级内核

    下载内核

    kernel-ml-6.4.11-1.el7.elrepo.x86_64.rpm

    kernel-ml-devel-6.4.11-1.el7.elrepo.x86_64.rpm

    1
    2
    3
    cp kernel* ~/rpm
    cd ~/rpm
    rpm -Uvh --force --nodeps *

    后续步骤见之前的文章：centos7.3升级内核

    升级内核后无法通过有线网卡上网，切换旧的内核，执行

    # 切换为	CentOS Linux (6.4.11-1.el7.elrepo.x86_64) 7 (Core)可以看到没有加载驱动，最后少了Kernel driver in use: r8169这一行
    rmmode r8169 #需要先移除才能加载成功
    modprobe r8169 #加载驱动成功就可以上网了,重启就会失效，需要重新执行这两个命令
    # 持久加载：如果您希望在每次系统启动时自动加载驱动程序，您可以将其添加到 /etc/modules 文件中。打开该文件并在末尾添加一行，写入您的驱动程序名称。保存文件后，下次系统启动时，该驱动程序将自动加载。

  3. 解压tar -zxvf iwlwifi-ty-59.601f3a66.0.tgz

  4. 安装驱动，执行cp *.ucode /lib/firmware

  5. 重启，执行reboot

  6. 配置网络nmtui

  7. vi /etc/systemd/logind.conf 去掉HandleLidSwitch前面的注释符号#，并把它的值从suspend修改为ignore，执行systemctl restart systemd-logind生效

方案一(成功解决)：

内核相关依赖https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/在里面找个最新的[ linux-firmware-20230804.tar.gz](https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/snapshot/linux-firmware-20230804.tar.gz) (sig)

wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/snapshot/linux-firmware-20230804.tar.gz
tar -xzvf linux-firmware-20230804.tar.gz 
cd linux-firmware-20230804
# 全部同意Y
cp iwlwifi-* /lib/firmware
reboot
nmtui
# 备份系统
tar cvpzf backup.tgz / --exclude=/proc --exclude=/lost+found --exclude=/mnt --exclude=/sys --exclude=backup.tgz --waring=no-file-changed
# 还原
tar xvpfz backup.tgz -C /
mkdir proc
mkdir lost+found
mkdir mnt
mkdir sys

方案二：网卡驱动冲突

#查看PCI设备（网卡、声卡、显卡、磁盘控制器、USB 控制器等）信息
lspci |grep -i network
# lspci commond not found
yum -y install pciutils
# 进入对应设备目录，删除多余版本的固件文件
cd /lib/firmware/ath10k/<网卡名字>/<硬件版本>/

方案三：centos 配置无线网卡、centos7无线网卡

nmcli radio wifi on
