Wifi card is a small component in your laptop you can't choose. Lucky if you get a common, fine working wifi card with Linux kernel. Recently I got a laptop with Realtek rtl8821ce that has a serious issue with newest Linux kernel (5.11.x and above). The wifi card becomes so slow after I did a system upgrade. Apparently, the issue is caused by inappropriate driver loaded by the newest Linux kernel that makes the wifi card works less than a decent performance we should get. The solution is quite simple. You have to install the appropriate driver from Ubuntu's official repository: Connect to internet using your Android's USB thethering connection. Install this following package: sudo apt install rtl8821ce-dkms Reboot your system
