I took a look at the most relevant question, and am a step further but am not sure where to go from here.
I am currently trying to connect two ethernet interfaces but am having trouble establishing a connection to both interfaces at the same time. When I connect the second interface
enx000acd2f045e my connection through
enp0s31f6 to the Internet is disconnected. And unlike the cited answer, neither of my networks are disabled when I run
sudo lshw -c network.

The answer did mention checking my routing table, stating that I can't have more than one gateway. So I ran the following:
Before connecting to
$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 188.8.131.52 0.0.0.0 UG 100 0 0 enp0s31f6 184.108.40.206 0.0.0.0 255.255.255.0 U 100 0 0 enp0s31f6 220.127.116.11 18.104.22.168 255.255.255.255 UGH 100 0 0 enp0s31f6 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 enp0s31f6
After connecting to
$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.3.3 0.0.0.0 UG 0 0 0 enx000acd2f045e 0.0.0.0 22.214.171.124 0.0.0.0 UG 100 0 0 enp0s31f6 126.96.36.199 0.0.0.0 255.255.255.0 U 100 0 0 enp0s31f6 188.8.131.52 184.108.40.206 255.255.255.255 UGH 100 0 0 enp0s31f6 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 enp0s31f6 192.168.3.0 0.0.0.0 255.255.255.0 U 0 0 0 enx000acd2f045e
Finally, he states "If you have two gateways, your routing table would have a double entry for dest 0.0.0.0 and the system can't handle this." I'm relatively new to networks and am not sure what I can do to fix this. It appears I may have a conflict on the first two rows of my routing table.
- Should I update:
- the default gateway found in Ubuntu's Network menu OR
/etc/network/interfaces, this doesn't seem to be used for much in recent versions of Ubuntu let alone 16.04
