请帮我。
答案1
通过dkms status命令我们可以看到只安装了一个蓝牙 dkms 驱动，但是没有安装 wi-fi 和 radeon 驱动。这很可能就是 wi-fi 无法正常工作的原因。

我假设您正在使用4.18.0-16-generic内核运行，是吗？
您从哪里获得 Wi-Fi 和 Radeon 驱动程序？
在 18.10 更新之前 Wi-Fi 能用吗？
更新＃1：
在terminal...
sudo dkms build oem-wifi-qualcomm-ath10k-lp1734600-4.4/4.1
如果构建成功，那么...
sudo dkms install oem-wifi-qualcomm-ath10k-lp1734600-4.4/4.1
如果安装成功，那么...
dkms status
尝试无线网络。
更新 #2：
这个 dkms 模块已经很久没有使用了，所以我们将其删除...
sudo dkms remove radeon-si/1a -k 4.4.0-38-generic
更新 #3：
此 dkms.conf 模块是针对早期内核硬编码的，因此它不会在当前内核上构建。所以我们也将其删除...
sudo dkms remove oem-wifi-qualcomm-ath10k-lp1734600-4.4/4.1 -k $(uname -r)
