+## Ethernet
+
+If your `eth0` interface is not listed in `ip addr` output, you may consider blacklisting default `r8169` kernel module and installing `r8168` as a replacement module. 
+
+**1)** Add `blacklist r8169` into `/etc/modprobe.d/ethernet.conf`:
+
+```
+echo "blacklist r8169" | tee -a /etc/modprobe.d/ethernet.conf
+ 
+```
+
+**2)** Install [r8168-dkms](https://aur.archlinux.org/packages/r8168-dkms/) from AUR repository
+
+**3)** If you have `r8169` module loaded (`lsmod`), remove it with `rmmod r8169` and load installed `r8168` module (`modprobe r8168`)
