Thank you Ilario for all that nice info.
I followed your recommendations to install my nanostation M5 XM and,
after several issues, I managed to do it. However, it has no wifi.
Any advice on how to troubleshoot it?
I ssh it through ethernet and see memory is ok (it is indeed an XM!),
wifi is enabled (etc/config/wireless shows option disabled 0), and the
lime-autogen file shows the same contents as a healthy nanostation M5 XW
that is working ok.
I think this Nanostation M5 is an XM as it does
not show XW.
How can I make sure whether it is an XM or an XW?
Verry goodd questionn.
Looking quickly on the internet seems that you can check the processor
and the RAM size for understanding if it is XM or XW. The reference
values are here:

I have just tried with your image, Ilario.
I could flash it, but it does not work properly. The router shows the
SSIDs for some seconds and suddenly they are gone, and it repeats this
behavior every few minutes. Moreover, Ethernet connection does not work
either.
Does anyone have any Nanostation M5 XM working with the last LiMe version?
I think the XM is a low flash and memory device. Maybe that is the problem?
Yess, the XM has just 32 MB of RAM (the flash memory is not a problem, 8
MB are enough), while the latest OpenWrt release recommends at least 64
and the next OpenWrt release will not even be compiled for 4/32 devices:
https://openwrt.org/supported_devices/432_warning#supportability_issues
If that is the problem, could I compile a LiMe
image with the mininum
software so that the XM works?
Yesssss, good idea.
Please let me know if you have any recommendation
on things to remove to
get a minimalistic LiMe. I don't need the Nanostation to be an Access
Point, it's just for backhaul.
What takes a lot of RAM I suppose is the web interface.
You can compile taking just the first packages from the development page
(i.e. do not install check-date-http and all the other packages listed
after this):
https://libremesh.org/development.html#compiling_libremesh_from_source_code
BUT *avoiding to select lime-app*.
This way, you should have an image without uhttpd.
I hope I can find a solution, because I have many
old nanostations :(
Nice!
Using old hardware is cheaper and way more sustainable than buying new
stuff :D
