Ubuntu 20.04.6 LTS双系统下“No Wi-Fi Adapter Found”问题求助

Ubuntu 20.04.6 LTS双系统下“No Wi-Fi Adapter Found”问题求助

大家好,我在Ubuntu 20.04.6 LTS双系统环境中遇到了无线网卡无法识别的问题,系统一直提示“No Wi-Fi Adapter Found”。我尝试运行了几个硬件排查命令,下面是具体的输出结果,希望能得到社区大佬的帮助!

首先是执行lspci命令的输出:

00:00.0 Host bridge: Intel Corporation Broadwell-U Host Bridge -OPI (rev 09)
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 5500 (rev 09)
00:03.0 Audio device: Intel Corporation Broadwell-U Audio Controller (rev 09)
00:14.0 USB controller: Intel Corporation Wildcat Point-LP USB xHCI Controller (rev 03)
00:16.0 Communication controller: Intel Corporation Wildcat Point-LP MEI Controller #1 (rev 03)
00:19.0 Ethernet controller: Intel Corporation Ethernet Connection (3) I218-V (rev 03)
00:1b.0 Audio device: Intel Corporation Wildcat Point-LP High Definition Audio Controller (rev 03)
00:1c.0 PCI bridge: Intel Corporation Wildcat Point-LP PCI Express Root Port #1 (rev e3)
00:1c.2 PCI bridge: Intel Corporation Wildcat Point-LP PCI Express Root Port #3 (rev e3)
00:1c.5 PCI bridge: Intel Corporation Wildcat Point-LP PCI Express Root Port #6 (rev e3)
00:1d.0 USB controller: Intel Corporation Wildcat Point-LP USB EHCI Controller (rev 03)
00:1f.0 ISA bridge: Intel Corporation Wildcat Point-LP LPC Controller (rev 03)
00:1f.2 SATA controller: Intel Corporation Wildcat Point-LP SATA Controller [AHCI Mode] (rev 03)
00:1f.3 SMBus: Intel Corporation Wildcat Point-LP SMBus Controller (rev 03)
00:1f.6 Signal processing controller: Intel Corporation Wildcat Point-LP Thermal Management Controller (rev 03)
05:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5227 PCI Express Card Reader (rev 01)

接着我用sudo lshw -C network命令查看网络设备,输出如下:

*-network

从上面的输出里,我只能看到有线网卡(enp0s25)和通过USB共享的网络(usb0),完全找不到无线网卡的相关信息。我已经试过重启系统、尝试重新安装无线驱动,但都没有解决问题。有没有朋友能帮我分析下这是什么原因,或者给出一些可行的修复方案呢?
