Hi Gary,
when the loss happens, for how long does it happen? Do you see where/why the
ping packets get dropped? That should be the first step to find out, IMHO.
Changing the gateway should be working in general [1]. It's also possible that
the loss is mesh related and the gateway change happens due to a node failing
in your mesh - that would be a problem independent of BLA.
I hope those suggestions help you to find out the problem. :)
Cheers,
Simon
