Ubuntu 20.04 on T14 gen 1 amd the wifi does not work

es flag

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?

Let's gather some details about your wireless device. Please open a terminal Ctrl+Alt+t and run: `lspci -nnk | grep 0280 -A3` Next, edit your question to show the result. Welcome to Ask Ubuntu.

You need to install the rtw89 driver for your 10ec:8852 wireless. Please see the duplicate for the procedure. https://askubuntu.com/questions/1352260/wifi-adapter-not-found-realtek-10ec8852-on-ubuntu-21-04

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

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
