I bought a new Lenovo Ideapad 5 without any OS. I installed Ubuntu 20.04 on it. However, in Settings -> Wi-Fi I see "No Wi-Fi Adapter Found". I already spent hours trying to solve this problem. I don't know, what I'm missing.

Here, I paste the output from some common commands I found.

sudo lshw -C network *-network UNCLAIMED description: Network controller product: Realtek Semiconductor Co., Ltd. vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 version: 00 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress cap_list configuration: latency=0 resources: ioport:2000(size=256) memory:d0500000-d05fffff *-network description: Ethernet interface physical id: 2 bus info: usb@3:2 logical name: usb0 serial: 16:00:4c:38:bb:e6 capabilities: ethernet physical configuration: broadcast=yes driver=rndis_host driverversion=22-Aug-2005 firmware=RNDIS device ip=192.168.42.59 link=yes multicast=yes

Also, in Software & Updates -> Additional Drivers there is "No additional drivers available"

I have no idea, what to do next. Please, help.

To get the realtek 8852 PCI adapter working with Ubuntu, follow these steps:

  1. Download dependencies:

     sudo apt-get update sudo apt-get install make gcc linux-headers-$(uname -r) build-essential git

  2. Install 'fix':

    git clone -b v5 cd rtw89 && make && sudo make install

  3. load module:

    sudo modprobe rtw89pci

    If you are lucky, this is all you will need to do. The driver should be loaded. If not, you will likely know. The driver load attempt will have caused an error. If this is the case, click the source link below for details.
