我一直在尝试让我的 Cudy AC650S wifi 适配器在 Ubuntu 20.04(内核 5.4.0-51)上运行,但在尝试了所有我能在网上找到的解决方案后,到目前为止都失败了。这就是我现在在这里问的原因。似乎 Cudy 提供的驱动程序仅适用于 Ubuntu 18.04,而不适用于 20.04(https://www.linux.org/threads/installing-a-usb-wifi-unit-in-ubuntu-20-04.29202/page-2)所以我从 Github 安装了这些驱动程序:https://github.com/brektrou/rtl8821CU
系统似乎确实识别了该适配器。当我使用时,inxi -n
输出如下:
Network: Device-1: Intel Centrino Advanced-N 6235 driver: iwlwifi
IF: wlp2s0 state: up mac: c4:85:08:41:69:b4
Device-2: Realtek 802.11ac NIC type: USB driver: usb-network
它还出现在lsusb
但是,当我检查时,它没有显示为网络设备lshw -class network
。这是我得到的所有输出:

同样,iw dev
其上仅显示:

我现在有点迷茫,不知道问题出在哪里。驱动程序安装是否不正常?或者我还能做些什么来“激活”适配器?
您可能已经看到了,我是 Ubuntu 的新手,但到目前为止,我总是能够使用这里和其他地方提供的提示解决我的问题。但这次我已经没有主意了。任何帮助都将不胜感激!
更新:Hier 是lsusb
