I have a Cubietruck board with 16.04 Ubuntu (armbian base) installed.

In the past I've used the board with a static IP address, defined in /etc/network/interfaces.

Today I wanted to expand my network a bit, and put a dlink router in a kind of repeater/switch mode (no wireless, no dhcp, only extending the network of the main, Mikrotik router). In the meantime, I wanted to change the board from static IP, to DHCP, with a fixed DHCP configured in the router.

My problem: I tried setting both DHCP and static configuration on my board, either connecting to the main router or the repeater, but I could not receive a working IP address.

The configurations I've tried:

for DHCP

auto eth0
allow-hotplug eth0
iface eth0 inet dhcp

for static

auto eth0
allow-hotplug eth0
iface eth0 inet static
 address 192.168.88.42
 netmask 255.255.255.0
 gateway 192.168.88.1 # also tried 192.168.88.2 which is the repeater

On the Mikrotik router, there is no static DHCP address set yet.

What I found while trying:

• WiFi with wlan0 (originally used through armbian-config) works perfectly with dhcp and no entry in the interfaces file.


• dhclient tried requesting an older, 192.168.1.42 address, but I removed the dhclient.eth0.leases file


• dhclient tries querying the 255.255.255.255 address, with no success.


• ip addr show says the state of the interface is DOWN


• ifconfig says when listing the interface: Interrupt: 51

Does anybody has any idea what could be my problem?

Edit: With this double router setup, other devices (an RPI2) do work.
