I have recently purchased a Lenovo ThinkPad T14 (Gen 1) notebook and, when I installed ubuntu 20.04, the wifi stopped working. I have updated all of the drivers, but the wireless card does not work.

This is the output of lspci -nnk | grep 0280:

03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:8852] Subsystem: Lenovo Device [17aa:4852]
04:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS522A PCI Express Card Reader [10ec:522a] (rev 01) Subsystem: Lenovo RTS522A PCI Express Card Reader [17aa:5082]

How can I use WiFi on this notebook?

For someone who installing Ubuntu on their T14 gen 1 AMD and get the same error, and can find /usr/lib/firmware/rtw89/ when trying ubuntu live version. Simply try enabling the module: sudo modprobe rtw89pci
