Its the LAN card. Run

sudo modprobe -v r8168

03:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. Device [10ec:b822]

This is wireless. Run

sudo modprobe -v rtl8822be

[CODE]
modprobe: FATAL: Module rtl882be not found in directory /lib/modules/4.13.0-31-generic

Lets check

dpkg -l linux-image-* | grep ii
dpkg -l linux-headers-* | grep ii
locate r8168.ko | grep lib
locate rtl8822be.ko | grep lib

The 2 other commands didn't output anything... even without the pipe to grep... nothing

What about results for

dkms status

[praseodym]

Ok, download these files (somehow) and save them in "Downloads":

http://de.archive.ubuntu.com/ubuntu/...5.08-1_all.deb

http://de.archive.ubuntu.com/ubuntu/...tu11.5_all.deb

Installation

sudo dpkg -i ~/Downloads/*.deb
echo "blacklist r8169" | sudo tee -a /etc/modprobe.d/blacklist.conf

Reboot. If LAN works, install the wireless driver via

sudo apt-get install git build-essential dkms linux-headers-$(uname -r)
git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
sudo dkms add ./rtlwifi_new
sudo dkms install rtlwifi-new/0.6
sudo cp /usr/src/rtlwifi-new-0.6/firmware/rtlwifi/* /lib/firmware/rtlwifi/

Reboot with SecureBoot deaktivated

Try Ukuu to upgrade your kernel. This could solve your problem.
