+# Network
+
+## Wifi
+
+Being able to connect to the internet is essential so let's set it up. Although `dhcp` will already work out of the box, wifi will not. Luckily there exist `wpa_supplicant`. First install the necessary packages:
+
+```
+# apk add networkmanager-wifi wpa_supplicant
+```
+
+Then configure `/etc/NetworkManager/NetworkManager.conf` to use `wpa_supplicant`:
+
+```
+[main] 
+dhcp=internal
+plugins=ifupdown,keyfile
+
+[ifupdown]
+managed=true
+
+[device]
+wifi.scan-rand-mac-address=yes
+wifi.backend=wpa_supplicant
+```
+
+Now restart the service and you should be able to connect to the Wifi.
+
+```
+# rc-service networkmanager restart
+```
+
+There are different frontends to configure connections but for now lets install `networkmanager-tui`:
+
+```
+# apk add networkmanager-tui
+# nmtui
+```
+
+It should be pretty self-explanatory on how to use it.
+
+## VPN's
+
+NetworkManager can already use WireGuard but to use other VPN types it might be necessary to install their corresponding plugin. For OpenVPN that would be:
+
+```
+# apk add networkmanager-openvpn
+```
+
+## Security
+
+NetworkManager's defaults are fine for normal usage but for security sake they are definitly lacking.
+
+### MAC Randomization
+
+Create a config file `/etc/NetworkManager/conf.d/mac-rand.conf` to randomize te mac address for every time your computer connects:
+
+```
+[connection-mac-randomization]
+ethernet.cloned-mac-address=random
+wifi.cloned-mac-address=random
+```
+
+### IPv6 privacy
+
+Edit `/etc/NetworkManager/conf.d/ip6-privacy.conf`:
+
+```
+[connection]
+ipv6.ip6-privacy=2
+```
+
+### Macchanger
