Hmm. This looks pretty much exactly like what I already tried (I had
fixed Johannes' patch to use "vht_cap" already, since it didn't
compile otherwise).

So the only difference is that it only checks WIRELESS_MODE_AC_5G.

But it worked for me this time. I have no idea why.

Maybe Johannes' patch actually always worked for me, but I just had a
transient problem that made me think it didn't. I think I only booted
it once, and went "oh, ok, no network, that didn't work".
