Richard and Theo would probably roll their eyes at this point
but the unfortunate reality is that wireless hardware is very
much dependent on firmware being explicitly provided; so here
it is.

rtl8192 kernel module added since it's present in t6/branch
at least.

It's a next-get CLI for wireless interfaces, see also

The creeping wireless bits should be thrown together,
including kernel modules, firmware, CLI/GUI controls,
and any plumbing required.
