ubuntu 19.04:AWUS 036ach wifi 适配器不工作

该设备以前可以正常工作,但现在我无法使其工作,因为我使用的是 19.04 版本(我从 18.04 升级而来)。我有另一个 TP-LINK wifi 适配器,它可以工作,所以我不知道会发生什么。我运行了在同一个论坛上找到的一个命令,这是输出:

当 Ubuntu 19.04 发生任何小更新时,就会出现此错误

您需要在 Ubuntu 终端中运行以下命令,确保您需要连接以太网电缆以在 Ubuntu 19.04 中启用 wifi

  1. $ sudo apt remove bcmwl-kernel-source && sudo apt install git dkms
  2. $ git clone -b extended https://github.com/lwfinger/rtlwifi_new
  3. $ sudo dkms add ./rtlwifi_new
  4. $ sudo dkms install rtlwifi-new/0.6

之后,您需要重新启动系统。现在您的 Wifi 连接将在 Ubuntu 19.04 PC 上启用。
