几周前,我的 wifi 信号很差。我设置了一些选项,/etc/modprobe.d/ath9k.conf
情况有所改善。现在我的信号又开始随机下降,我尝试安装backport-iwlwifi
。现在 Wifi 图标根本不出现,当我检查“设置 -> Wifi”时,我收到以下消息:未找到 WiFi 适配器。
当我尝试时,sudo modprobe -r ath9k
我得到了modprobe: FATAL: Module ath9k is in use.
这样的结果:这从来没有发生在我身上。
我尝试重新安装ath9k
Linux 固件,但没有成功。
我的 Linux 5.3.0-51-generic #44~18.04.2-Ubuntu SMP Thu Apr 23 14:27:18 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
:。
我不知道哪些信息可能有帮助,因此这里列出其中一些:
