Mesa 7i96s 5v supply reverse polarity damage

Tried a different windows PC to ping the mesa card and it seems to work user lights come on.Here is the ping data. 

 

Ok, not sure what happened but after connecting to the windows PC and pinging I can now ping it on the linux PC, left two user lights are solid green.

--- 10.10.10.10 ping statistics ---
145 packets transmitted, 145 received, 0% packet loss, time 146489ms
rtt min/avg/max/mdev = 0.148/0.368/0.618/0.133 ms

How do I keep the wifi working while connected to the Mesa card?

If you disconnect/reconnect the card this will typically update the interface settings to the latest
(the ifup/ifdown scripts run)

Not sure why you have a WIFI issue unless you are using wicd
(instead of network manager). Wicd is broken if multiple interfaces
are present

I am using NetworkManager Applet v1.30.0
Is there any other boxes to check in the setup for the Mesa Ethernet or should it just work?

I clicked the use this connection only for this network in the routes and that seemed to work now.

Thanks for the help! Getting closer all the time.
