Is this 18.04 'Beaver? I was surprised it did not seem to come with ifconfig
but did have iwconfig. I've seen problems like this because another interface
is up. Off hand I'm not sure how to check the routing but  on older 
Ubuntu you can try,
first I'm curious if you have ifconfig lol, and ifdown all the interfaces
and just bring up the wireless. The dhclient and see if you get an ip address
from your access point. I'm not sure if you have to do anything with wpa_supplicant
etc though ( I wrote a script to turn an older machine into a router
that let me check network traffic with tcpdump and all I rememebr right
now is that it could be a hassle- I put a wireless router on eth0 and 
a USB wifi stick to connect to the rest of the world  ).

Also traceroute and see where it is trying to go with whatever you want
to send over the wireless.
