Ubuntu 18 USB Realtek 8188eus

如何解决Ubuntu 18 USB Realtek 8188eus

我是从github安装的。但是它在gnome网络面板中显示“ Wifi Networks设备未就绪”。

iwconfig

struct Wrapper<DataT>
where
    DataT: AsRef<[u8]>,// <-- new trait bound
{
    data: DataT,}

impl<DataT> Wrapper<DataT>
where
    DataT: AsRef<[u8]>,// <-- new trait bound
{
    fn subwrapper(&self) -> Wrapper<Vec<u8>> {
        let buffer = self.data.as_ref() // <-- use `.as_ref()` to get `&[u8]`
            .to_vec();                  // <-- more efficient way to get `Vec<u8>`
                                        //       from `&[u8]`
        Wrapper { data: buffer }
    }
}

fn main() {
    let data: [u8; 3] = [1,2,3];
    let w = Wrapper { data: &data }; // <-- no need to use `[..]` here,as
                                     //       `[u8; N]` implements `AsRef<[u8]>`
    let sub = w.subwrapper();
}

lshw -c网络结果

ifconfig结果。

我该怎么办？
