Max Transit Cat 18 and Netgear 5100 as WAN trouble!

Hi all. First of all, really appreciate the help. I am struggling with trying to get my netgear nighthawk 5100 to work as either a wireless WAN or wired wan on my max transit cat 18. The netgear works just fine when connected to my laptop alone, by the max transit doesn’t like it for some reason. It shows as connected, but no internet access (ping, tracert, etc come up empty). I have disabled all other WANs except this one for testing purposes.

Is there something simple that I’m missing here?

Thanks everyone!
