I installed Ubuntu 22.10 a few days ago after Windows just became too boring. But I had one problem where my Wi-Fi connection was pretty slow and I had no problems with my network before. I searched the internet and most of the sources said I should install my drivers. I checked what my wireless adapter was by using:
lspci |grep "Network controller"
It gave the output 'Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter' so I searched the internet to install the specific drivers and I found something.
sudo apt-get install dkms sudo apt-get install rtl8821ce-dkms
The second command gave me a package not found error and another source said I should enable the multiverse and universe APT repositories and try again but to no avail. Then I checked the https://packages.ubuntu.com website and searched the package name but it just showed that the package was available for Ubuntu 20.04 and 22.04. What should I do to install the drivers? Nothing shows up on Additional Drivers. Thanks.
