You probably want something like:
# dhcpleased -dvv 2>&1 | tee /tmp/logfile
... as dhcpleased is writing to stderr and tee only captures stdout.

As Florian also points out, this is a reply being received from the router.
So although the other tests initially suggested that you might have had an
issue with 2.5 Ghz vs 5 Ghz operation, (I.E. no Tx on 5 Ghz *, which would
point to the iwm driver code), now we see that at least the DHCPNAK packet was
received from the router by your iwm device, so it's not a simple, 'rx isn't
working on 5 Ghz' issue.
(*) although there must have been at least some Tx to connect to the AP in the
first place, so I was a bit dubious about that.
Having said that, for completeness I guess it could still plausibly be
something very specific, such as a specific packet size or content that was
triggering a bug in the driver code and preventing the request going out, but
I would put that possibility as a distant last.
Next step would be to try what Stuart suggested and test a different dhcp
client:

You disable it, either with something like:
# rcctl set dhcpleased status off
or by just editing /etc/rc.conf.local and adding:
dhcpleased_flags=NO
(which is basically what the rcctl command above would do anyway).
Also, are you running the most recent firmware on the router?
