联想 s145 wifi 驱动程序

（新 Ubuntu 用户）

我正在使用联想 S145 笔记本电脑，想使用 Ubuntu。

安装后（18.04 LTS，5.3 内核），无法识别 wifi，并且在设置中出现“未找到 Wi-Fi 适配器”。

我尝试过不同的解决方案，例如https://github.com/lwfinger/rtlwifi_new但我不知道我应该使用哪个驱动程序，或者我所做的任何事情是否真的会影响任何事情。

一些额外的信息：

（我猜以太网接口是我的 Android 设备的 USB 网络共享）

答案1

rtlwifi-new 可能能够支持这一点，在终端中执行 

cd rtlwifi_new
git checkout rtw88
sed -i 's/0xC822/0xC82F/' pci.c
make
sudo make install

重启

必须禁用安全启动

在终端运行wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && chmod +x wireless-info && ./wireless-info
