我的 wifi 似乎工作正常，但如果是我的笔记本电脑，有时它会停止工作，但同时在我的手机中，我可以看到互联网工作正常。
我的网络信息：
shashank@shashank:~$ lspci -v | grep -i network -A 6
03:00.0 Network controller: Qualcomm Atheros Device 0042 (rev 31)
Subsystem: Lite-On Communications Inc Device 08a6
Flags: bus master, fast devsel, latency 0, IRQ 132
Memory at b4000000 (64-bit, non-prefetchable) [size=2M]
Capabilities: <access denied>
Kernel driver in use: ath10k_pci
Kernel modules: ath10k_pci
同样通过很少的研究，我知道我们可以在发生某些事情时看到消息dmesg，如果我错了，请纠正我。
所以在分析了这个输出之后，我注意到了这一点：
