有什么建议吗？顺便说一下，我的 wifi 工作正常。

很抱歉，但您的设备的驱动程序似乎已经纳入 Linux 内核。
在我的带有 4.15 内核的 Ubuntu 18.04.1 LTS 上，我有以下输出modinfo ax88179_178a：

驱动程序可能安装有
sudo apt-get install linux-modules-extra-$(uname -r)
如果您愿意，您可以使用 Trendnet 提供的驱动程序：
cd ~/Downloads
wget http://downloads.trendnet.com/tu3-etg/utilities/linux_tu3-etg.zip
unzip linux_tu3-etg.zip
make
sudo make install
sudo modprobe usbnet
sudo insmod ax88179_178a.ko
如果此方法无效，请使用以下命令删除 Trendnet 驱动程序：
sudo rm /lib/modules/$(uname -r)/kernel/drivers/net/usb/ax88179_178a.ko
sudo /sbin/depmod -a
并使用以下方法从存储库重新安装内核模块包
sudo apt-get install linux-modules-extra-$(uname -r) --reinstall
注意：刚刚测试了 D-Link DUB-1312 (2001:4a00)，即使在使用预安装的内核模块的 Linux 4.4 的 Ubuntu 16.04 LTS 上，它也可以正常运行ax88179_178a：

答案2
我和楼主的笔记本电脑一模一样，都是 Ubuntu 18.04，问题也一样。对我来说，解决方法是拔下/重新插入 USB 以太网适配器，而无需将以太网电缆插入适配器。之后，lsusb我的设备显示为：
Bus 002 Device 025: ID 0bda:8153 Realtek Semiconductor Corp.
Bus 002 Device 024: ID 05e3:0616 Genesys Logic, Inc. hub
此后，可以重新插入以太网电缆。我已经在路由器端准备好了 dhcp，因此此时以太网已启动并正确连接（使用“ip address show”检查）。
注意：我的以太网 USB 加密狗硬件可能与 OP 不同，但该解决方法值得一试。
如果在插入设备的 USB 端之前先插入以太网电缆，USB 以太网设备将无法正常启动，这是一个错误吗？在我看来，这似乎是不正确的行为。
