Please don't use things like wl1835 when building larger meshes. It is known 
that these kind of  devices only support a very limited amount of peers and 
are most of the time only (more or less) stable in management mode (client).
And afaik, the wlcore driver (like other TI wirelss drivers) is also orphaned.

If you're wifi link/driver doesn't work, batman-adv can also do nothing to fix 
it.

Rule of thumb: If it is a USB/SDIO wifi device, start waving your hands in the 
air, scream and run away. This strategy is also helpful in other wifi related
situations.

Kind regards,
	Sven
