答案1
硬件可能是完全专有的或只是块。
lspci -k
-k 选项显示处理每个设备的内核驱动程序，如手册中所述
然后
rfkill unblock all && rm -rf /dev/rfkill && reboot
这将解除对 rfkill 的所有默认情况下可能被阻止的内容的阻止
答案2
从输出来看，似乎您已经r8723bs加载了 wifi 的驱动程序模块lsmod。驱动程序是否说 的输出有什么问题dmesg？
如果您缺少其/lib/firmware/rtlwifi/rtl8723bs_nic.bin固件，请注意，您可以替换rtl8723bu_nic.bin，因为固件的这一部分可以在两者之间互换，如果您没有，您可以从发行版提供固件的方式或从上游获取它：
