Hey there, really appreciate the help. Responses below.

How are you connecting via wifi to the hex? You have a simple access point connected on the lan side of the hex that does no routing at all, I assume, is this correct?

- ISP Router: out the first internet port <ethernet> hex: into internet/first port
- hex: out the second port <ethernet> LiMe wdr4300: into internet port
- hex: out the fourth port <ethernet> into computer

In any event, it looks like your computer is hard-set [meaning in system options or via ifconfig/ipconfig] to use itself as the DNS server [strange config btw, is this a server?] when using the wifi interface [127.0.0.1] whereas it’s not hard-set to a specific DNS server when using the wired interface.

Its Ubuntu 16.04 x64. I use a lot of virtualization (virtualbox, lxc) so the bare-metal I'm running from should be fairly close to a stock ubuntu install.

Is your computer getting an IP automatically from the HEX when connecting to it via ethernet? Could you post the result of command ifconfig

Secondly, could you try [always via ethernet] to nslookup wikipedia.org 172.16.0.1

$ nslookup wikipedia.org 172.16.0.1
Server: 172.16.0.1
Address: 172.16.0.1#53

** server can't find wikipedia.org: SERVFAIL

and nslookup wikipedia.org 8.8.8.8 ?

Server:        8.8.8.8
Address:    8.8.8.8#53

Non-authoritative answer:
Name:    wikipedia.org
Address: 198.35.26.96

Thanks

Hey, I'm replying with two sets of commands. The first is always using WIFI which is working fine. The second is connecting my computer to the hex via ethernet, which does not work well.

I'm pretty sure its not my computer's ethernet. I've also tried connecting my computer directly into the isp router via ethernet and that works fine.

Working version using hex<WIFI>computer:
