Problem with RTL8821 network card connecting to college Wi-Fi.
Problem with RTL8821 network card connecting to college Wi-Fi.
I recently switched my laptop OS to Ubuntu 18.04.02. The main issue was that Ubuntu didn’t support the drivers for my network card (RTL8821). I resolved it by installing drivers from a GitHub repository, which worked on my home Wi-Fi. At college, the problem changed because the college Wi-Fi used 802.1x encryption, making it hard for the drivers to connect. Any suggestions on how to handle this? Feel free to share more details, and don’t worry—I’ll guide you step by step since you’re new to Linux. Thanks.
You're correct, the issue likely lies with the driver. It can vary depending on the operating system. There aren't many specific recommendations since details are limited.
He mentions 802.11-Enterprise for connecting via WiFi using your Active Directory credentials. The wireless protocol isn't crucial here since the card supports up to 802.11ac.
On the Ubuntu community site, you'll find details about which wireless cards are supported.
I believe your institution is implementing WPA enterprise, so you should navigate to the advanced configuration and set it up accordingly.
I encountered some issues with my network card and the university's WPA enterprise network. It seems to depend on whether you need any certificates for the network. In my case, eduroam required the proper certificate, but you can skip this by checking the "no CA certificate required" option. Also, make sure the username and password you're using are correct.
