Pi3 & Navio2 Connection problems


I have the raspberry pi3 and attached the Navio2 to it. The Raspberry pi3 has on-board wireless (no dongle needed)

Before I attached the Navio2 I was able to test the Raspberry with the Raspian image and it connected fine to my wifi which is IPv4.

Then I re-imaged the card with the Emlid image and installed and booted my Raspberry. It boots fine but I see errors when it tries to do a sudo apt-update command and I do not see it on my network.

Last night I attached an ethernet cable to the Raspberry and my router and it was able to get online and do the updates, but if I remove the ethernet cable it still will connect to the wifi.

It is very similar situation to this, but I am not sure how it was resolved.
