我为我的 Ubuntu 20.04 买了一个 TP-Link UE300 V.3 适配器，内核版本为 5.13.0-35-generic，但它不起作用。我“有线连接”并有 100MB/s。我试过了，sudo dhclient -r但sudo dhclient没有用。我有华硕 Vivobook S14/S15。我正试图连接到学校的公共网络，所以我无法对路由器做任何事情。电缆是 Cat5e。我尝试将电缆和适配器连接到装有 Windows 10 的笔记本电脑，它成功了，所以我猜问题出在我的笔记本电脑上。

我必须指定我尝试手动安装驱动程序https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-usb-3-0-software（Unix/Linux）以及 GIT：https://github.com/JulAlx/TP-Link-UE300-UE330-Linux-Driver但它不起作用。sudo make我输入了 Realtek 链接驱动程序Warning: modules_install: missing 'System.map' file. Skipping depmod.，但无法使用 vmware。
有任何想法吗？
编辑：忘了说了，当我拔掉笔记本电脑的电源超过 20 分钟时，它工作了几次。之后，当我再次拔掉电源并重新插入时，它就停止工作了。我没有真正的经验。
EDIT2：正如 chilli555 所说：
ping -c3 8.8.8.8：

ls -al /etc/resolv.conf：

现在启动笔记本电脑，有线连接 4 小时后没有问题。拔下电源再插上，还是无法使用。
ping -c3 8.8.8.8EDIT3：不知道为什么会有不同的地址。这是以太网正常工作时的答案：

您认为什么地方出了问题？
