Ok I did this:
config net mywan
option linux_name 'eth0'
list protocols 'wan'
started lime-config
rebooted
Seems to work
Question:
What is luci good for?
Can't see any change in /etc/config/network.
What also happened starting lime-config?

Wait, do not configure anything via LuCI web
interface, it could work
but it could as well not work at all!
Additionally, when you configure LibreMesh via lime-app or via SSH, the
changes you did via LuCI could be overwritten.
I suggest to stop using the one PicoStation with SquashFS errors, likely
it is broken.
Regarding the other PicoStation: I would flash it with a clean LibreMesh
(so that you start from a clean configuration) and configure the WAN via
SSH.
Connect to it via SSH and edit the /etc/config/lime-node adding these
lines at its bottom:
config net mywan
option linux_name 'eth0'
list protocols 'wan'
save and run the lime-config command and reboot.
There's no need to understand issue #658 :)
It basically says that if you connect a LibreMesh LAN port to a
non-LibreMesh LAN port weird things can happen.
In general, the valid connections are:
* LibreMesh LAN connected to LibreMesh LAN
* non-LibreMesh LAN connected to LibreMesh WAN
while the connections which should **never** be used (because very weird
things can happen) are:
* non-LibreMesh LAN connected to LibreMesh LAN (and this is #658)
* LibreMesh LAN connected to LibreMesh WAN (NAT could create troubles)
* LibreMesh WAN connected to LibreMesh WAN (no IP will be assigned and
in the future this could be broken due to the usage of OpenWrt's
firewall, see https://github.com/libremesh/lime-packages/issues/280)

Ok I added the WAN interface with physical
setting ETH0 and I deleted
ETH0 from LAN interface.
Then WAN is up and running and Luci >> overview shows connected to
router and the IP address.
Network Diagnostic ping to openwrt.org <http://openwrt.org> ok
But connected to AP no internet

I changed the MTU because of this advice:

Packets going over this interface will be fragmented on layer2 which
could impact the performance. Setting the MTU to 1532 would solve
the problem.
Having internet means I can browse the internet.
There is only one Picostation having the squashfs error but not
always and even then it is meshing.
I didn't config eth0 as WAN
Connecting immediately after boot device was unresponsive, Fing
listed all devices of my network, internet ok, distant node internet
as well
Then device rebooted and was responsive via anygw (10.236.0.1) Does
this mean I should wait a while?
Should I try to add the WAN interface manually?
I looked at the issue 658 but that is beyond my understanding ;-)

We always had the MTU message from Batman-adv and I think you can
increase the MTU over 1500 for an ethernet interface only if it
supports
jumbo frames (which usually happens for gigabit interfaces).
Contrarywise, on the wifi interfaces the limit should be higher
and we
can use an MTU that suites Batman-adv usage.
LibreRouter people in the list should know much more than me on
this topic.
On the squashfs error, I have no idea.
Looks like one of the two PicoStation's flash or RAM memory is
damaged.
Do you see that message in both PicoStations?
Can you specify better what you mean with "both have internet"?
Can you ping some internet domain from inside SSH on a router?
If you didn't configure the ethernet interface as WAN, it could
be that
the client you're connecting with has internet due to
https://github.com/libremesh/lime-packages/issues/658
but this would imply a very erratic behaviour, in which some
times you
accept the home router's DHCP offer (and the internet connection
works
BUT thisnode.info <http://thisnode.info> do not work and this
would explain why thisnode.info <http://thisnode.info>
stops working) and some times you accept the PicoStation's DHCP
offer
(and you do not have internet as you did not configure any WAN
interface).

This is weird.
The Picostation M2 is not emitting any accessible
network via
wifi?
It could be a RAM problem: Ubiquiti Picostation *2
have just 32
MB of
RAM memory.
Connect via ethernet cable and check the dmesg command
output,
looking
for any "out of memory OOM kill" message.
In order to have less memory usage you can disable the
web
interface
(LuCI or lime-app) with:
/etc/init.d/uhttpd disable
and reboot.
In case the problem was not a RAM limitation, please
upload
somewhere
the output of the lime-report command or, if you don't
have

This is normal instead: both vendor and OpenWrt
What the lime-hwd-openwrt-wan package is designed to
do is: check if
OpenWrt would use an ethernet port as
WAN, if positive,
configure that
port as WAN.
In this case, OpenWrt use the port as LAN and thus
lime-hwd-openwrt-wan
does not do anything.
In these cases what you have to write is an
interface-specific
