我已经用 Ubuntu 18.04 双启动了我的笔记本电脑,这已经很长时间了。但是,最近我似乎无法连接到任何无线网络,并且在 WiFi 设置中显示“未找到 WiFi 适配器”。我尝试了很多解决方案,但似乎没有任何效果。此外,我想补充一点,即使该lshw
命令也不会显示有关我的无线接口的任何信息。下面给出的是lshw
and命令的输出rfkill
。
sudo rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
。
sudo lshw -c network
< outputs nothing >
。
sudo lshw -short

编辑:即使Windows也无法检测到无线接口。
答案1
即使 Windows 也无法检测到无线接口。
应该是和硬件有关吧适配器可能是问题所在。
尝试访问该卡(它可能是一个小的附加卡) - 通常很容易做到...尝试卸载并重新安装该卡。然后重启并测试。
如果没有新的情况,请尝试将卡更换为可用的卡。然后重启并测试。寻找卡格式信息。基本上有三种卡:(旧)mini-PCI、mini-PCIe(全高或半高)或(新)M2。
如果没有什么新的情况,问题可能更严重……尝试使用 USB WiFi 适配器,但我预计还会出现其他硬件问题!
