I am on a new laptop, new to Linux but here is the information:

Laptop: HP Pavilion
Ubuntu Version: 20.04

I typed lspci -v in the terminal and I think this is the relevant part of the output:

```
01:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter
DeviceName: Realtek RTL8821CE 802.11 ac 1x1 WiFi + BT 4.2 Combo Adapter (MU-MIMO supported)
Subsystem: Hewlett-Packard Company RTL8821CE 802.11ac PCIe Wireless Network Adapter
Flags: fast devsel, IRQ 255
I/O ports at e000 [disabled] [size=256]
Memory at fea00000 (64-bit, non-prefetchable) [disabled] [size=64K]
Capabilities: <access denied>

```

Going to settings > wifi it says "No wifi adapter found". I can confirm that the wifi was working on the Windows boot, but I have replaced it entirely with Ubuntu now.

EDIT: So I have managed to connect to the WIFI now by going to additional drivers and choosing to use open source drivers. I don't know how optimal it will be though compared to the proprietary drivers?
