Ubuntu 18.04 booting to old DHCP address despite being set to static












0















I added a security system with 4 network IP cameras to my network, so I switched my computer and modem to use static IP's (MAC filtering). When I boot up Ubuntu is not connected to LAN. I go into network settings and see 3 Eno1 connections and one Wired Connection. The IP it's trying to use is my old (dynamic) ip address (192.blah.blah). Once I click into one of the other connections, the IP is suddenly right (10.blah.blah), Ubuntu connects to the LAN, and 2 of the 3 Eno1 connections disappear. I'm a little confused because there is no /etc/netplan/*.yaml file (even after I run sudo netplan generate) and my /etc/network/interfaces is as follows. Everything works right after I click into one of the four networks settings, it's just trying to boot with an old IP, one my router shouldn't be sending.



# interfaces(5) file used by ifup(8) and ifdown(8)
# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
address 10.10.10.2
netmask 255.255.255.0
gateway 10.10.10.1
dns-nameservers 208.67.222.222 208.67.220.220


What to do?
