Review on XVZ USB WiFi Adapter, 600Mbps Dual Band 2.4G/5G Wireless Network Card, Mini WiFi Dongle for Laptop/Desktop/PC, Windows10/8/8.1/7/Vista/XP/2000, Mac OS X 10.6-10.13 Support by Kenneth Harris

Well, this is a very good product because it is of very high quality and has a decent range and many possibilities. That being said, I had HUGE trouble getting their installation scripts to work correctly on Ubuntu 19.04. It kept throwing various errors, including various authentication errors and some issues with not wanting to find certain things that the install.sh script needed. So I found the solution and it's MUCH simpler than the manufacturer's "installation" guide: open a terminal and type these commands one by one. If you don't have "git" installed, you need to type sudo apt install git. After that continue. Step 1: Create a directory to build the driver: mkdir -p /build Then change to this directory: cd /build Step 2: Clone the driver data from the repository. Here you need to clone to a git repo and Amazon rejected my first review because it included the repository url. So if you just go upstairs and ask a repo question like "what is a repo?" I'll give it to you. Шаг 3: Соберите и установитеcd /build/rtl8821CUmakesudo make installШаг 3: Убедитесь, что это сработало и что драйвер действительно загружен в ваши модули ядра ls /lib/modules/$(uname -r)/kernel/drivers/net /wireless/realtek /rtl8821cuЭто сработало ОТЛИЧНО, и если это сработало для вас, теперь вы должны увидеть, что маленький USB-адаптер имеет мигающий синий светодиод, и он должен автоматически распознаваться сетевым менеджером вашего дистрибутива (может быть, не Arch, у вас может быть делать дополнительные вещи Therefore).
