1 alone didn't fix it. 1+2 did. Switching MTU from 1280 to 1350
immediately resolved the issue.
So I think it's all set now. I have three lime nodes forming a mesh
around my house. One of the lime nodes is connected over ethernet to the
hex.
I'll report back any issues and successes. Now that this is working,
we'll start setting up more clusters, all using the same exit node. I
suppose we'll eventually want to figure out how to connect using a lime
node only without a hex. I don't think it will be cost effective to have
a hex at every node that connects to the Internet. We almost had that
working before.

Ok so I think it’s one of two problems if not both
here:
1] DNS
2] MTU
In the first case, which seems more likely, your Hex isn’t providing
DNS correctly. See the last part of this video and follow just the DNS
settings part: https://www.youtube.com/watch?v=SW6AZ33go5U [this is
the video I followed for my howto in the first place with the
exception of a few things such as L2TP instead of PPTP of course.
In the second case, your MTU might be wrong. Have you followed the MTU
section of my video? If not [*likely you made the right choice as mine
was a simple empirical one-time experience*] why not? Have you set it
to 1350 or have you left it default? See this link for a packet
fragmentation ping test guide: http://www.tp-link.com/us/FAQ-190.html.
Let me know how it works out

That's weird. Sending that last email worked even though I am still
connected via ethernet. Websites still won't load.

https://lists.libremesh.org/mailman/listinfo/lime-users 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*
enp0s31f6 Link encap:Ethernet HWaddr xx:xx:xx:xx
inet addr:172.16.0.252 Bcast:172.31.255.255 Mask:255.240.0.0

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
