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
