因此,昨天我在我的 Dell Vostro 3480 上全新安装了 Debian 11,在配置过程中遇到了 DHCP 问题,因此我当时手动输入了 IP 和掩码。
安装完成后,我发现没有任何 Wi-Fi 图标,或者无法连接到我的家用调制解调器。
我做了以下事情:
lspci 输出
01:00.0 Ethernet Controller: Realtek Semiconductor Co. , Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)
02:00.0 Network Controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)

我能够看到之前发布过类似的问题在这里,我完全参考了这些帖子
因此,我下载了firmware-iwlwifi
文件从这里在我的 USB 驱动器上,然后我使用以下命令将文件安装到另一个目录
sudo mount /dev/sdb1 /media/usb
此后,我陷入/etc/apt/sources.list并在以下预定义行的末尾添加“非免费”,因此它看起来像这样:
deb http://security.debian.org/debian-security bullseye-security main contrib non-free
deb-src http://security.debian.org/debian-security bullseye-security main contrib non-free
此后,我进入 /media/usb,然后运行以下命令
sudo dpkg -i 固件-iwlwifi_20210315-3_all.deb

此后,当我重新启动设备(如建议的那样)然后再次登录并输入以下命令时:
lsmod | grep iwl
[什么也没发生]
在此之后,当我输入以下命令时,我能够看到 NetworkManager 已启动。
sudo systemctl status NetworkManager
NetworkManager.service - Network Manager
Loaded: loaded (/lib/systemd/system/NetworkManager.service; enabled; vendor preset: enabled)
Active: active (running) since Wed 2023-01-18 09:16:54 GMT; 35min ago

我现在对这个问题很困惑,任何有关此问题的建议或帮助都将非常有用。因为目前无法从这台机器访问互联网。
谢谢 !
