We dropped currently the work on getting chip support on resin. Or at least
we postponed it so I don't have any binaries. But at that point wifi was
working. I haven't played with the board lately so can't say too much about
it.

One thing I would do is:
1. compare the wifi firmware on yocto and debian ones
2. check the driver it uses (both the same?)
3. kernel versions?
