Hi!
I have serious doubts that some these families will
want, or be able
to afford, a new router.
New routers are $20. And if this is too high, we can try to fundraise
for equipment and then donate equipment.
And I think madwifi supports broadcom, but not all
chips support
mesh.
No, madwifi does not support broadcom. madwifi is old anyway. WRT54GL
uses binary blobs and support only 2.4 kernel (no Batman, no IPv4), only
G protocol. Open source b43 driver to my knowledge is very unstable.
