TX1 wifi problems

Hello all. Just got my TX1. Installed Jetpack2.3.1 with no problems. Then installed ROS.
I can SSH into TX1 using wired ethernet.
BUT. wifi does not seem to work. ifconfig on TX1 shows a wifi IP but I cannot ping it from remote computer. Also cannot SSH to it. Strangely fing on the network picks up the wifi IP but also cannot ping it !
What gives ?

Are you able to access the internet or network through WiFi through the Jetson side? Try using chromium-browser or something from the Jetson Ubuntu 16.04 desktop.

Is ethernet connected simultaneously? Just trying to rule out any adapter routing configuration. What’s the contents of your /etc/network/interfaces?
