Mmmh maybe it is because it uses ath10k-ct drivers instead of non-ct
ones (CandelaTech modified the driver allowing it to be better as AP but
they removed many other features, like mesh).

@gothos: in the Ansible compiling stuff (this one, I believe
https://gitlab.com/a-gave/libremesh-ansible-playbooks) can we specify
that all the ath10k should use the non-ct driver?

For compiling the images used for the network at Wireless BattleMesh v15
we used this configuration:

Very likely the same problem as above.
Actually, it is surprising that the mesh on the 2.4 GHz interface works.

Nice!!!

Yesss, this is a known issue. It has been fixed in the code of lime-app
web interface:
https://github.com/libremesh/lime-app/issues/378
but the fix has not yet have been included in any release yet.
The last release is from March 2022
https://github.com/libremesh/lime-app/releases
but there is much new code that was not included there.
We absolutely need a new lime-app release in order to have a new
LibreMesh release with lime-app (I hope that lime-app developers are
reading this).

Wait, what do you mean with "first boot wizard"?
There is a piece of software, in the lime-packages repository, with that
exact name, but it is not included in the LibreMesh releases.
https://github.com/libremesh/lime-packages/tree/master/packages/first-boot-wizard
Reasons for not including it in the releases are various. From my point
of view, it has a big bug which is that does work only on dual band routers:
https://github.com/libremesh/lime-packages/issues/661
and it is designed with a very specific network model in mind (which is
amazing for many communities, but not for all of them. If you like FBW,
obviously you can compile images including it).
So I suppose you refer to the lime-app web interface.

The IP of each node should be associated to its hostname here:
https://github.com/libremesh/lime-packages/blob/361645ee5c8ca19a0a60cbea5246708049b582cd/packages/lime-proto-anygw/files/usr/lib/lua/lime/proto/anygw.lua#L96C1-L99
But then I am not sure which one of the shared-state packages then
spreads the information to the other nodes.
Anyway, they run in cron every X minutes, so it is normal that it takes
time to spread the information.

Nice :D
