This suggests that you have a/ some allow-hotplug statements in
/etc/network/interfaces listing interfaces which don't exist or no such
statements and that something isn't brought up automatically because of
this. Instead of trying to guess at the cause of this, it's probably
going to be easier if you just posted the whole file here. After all,
it's not that large.

The output of

ip link

and

ip ro

would also be helpful.
