If anyone else is interested - I found a way to enable static ip's for ethernet and wlan interfaces.

You'll need to install a file like below under /etc/systemd/systetem/ and run the following commands:

systemctl enable ipconfig.service systemctl disable dhcpcd.service [Unit] Description=A description for your custom service goes here Requires=systemd-networkd.service After=systemd-networkd-wait-online.service [Service] Type=simple ExecStartPre=/bin/sleep 10 ExecStart=/bin/systemctl restart systemd-networkd.service [Install] WantedBy=multi-user.target

You'll also need to add this file under /etc/systemd/network/wlan0.network

[Match] Name=wlan0 [Network] Address=192.168.0.169/24 #DHCP=yes

Simply installing this service will allow most routers to keep the rb5 address the same when assigning IPs for a lease. Just comment #Address and uncomment DHCP to use dhcp.

You will also need to make sure to add the gatway to the routing table:

route add default gw $router_IP $network_interface

this is best to be configured as a oneshot service where the service has the field Requires=ipconfig.service
