Realtek Wifi适配器在20.04.1更新后停止工作

Question

原来的线程在这里：还原Realtek适配器操作

Realtek适配器在安装20.04.1之后已经工作了3-4个月，直到进行了Novubuntu20.04.1升级。它在那之后立即停止了工作。按照第一个线程中的建议，能够恢复操作，并相信DKMS的安装将防止将来发生故障。但几天前又失败了。在升级之后。我有2台几乎相同的计算机，它已经在#2中修复了，但在这台计算机#1中没有，我被要求发布一些测试：

在这台我称之为#1的计算机上，Realtek不工作。在我的另一台计算机上，我调用了#2，操作已按照链接中显示的指令恢复。我相信专家们想弄清楚的是为什么没有通过升级来保护Realtek驱动程序呢？

Answer 1

从评论中..。

dkms 信息.

dkms status显示..。

rtl8188fu, 1.0, 5.4.0-52-generic, x86_64: installed
rtl8812AU_8821AU_linux, 1.0, 5.4.0-52-generic, x86_64: installed

两个驱动程序都不是Realtek的正确驱动程序。我们移除它们..。

sudo dkms remove rtl8188fu/1.0 --all
sudo dkms remove rtl8812AU_8821AU_linux/1.0 --all

然后我们按照前一个问题的指示进行操作。
