It looks like "man ath" does not list all media and mediaopt values.
sure not because there are lots of different cards out with different
mediaopts so you need to read your hw-manual or your card can answer
ifconfig -m ath0
In any case I imagine there is no point forcing it to use 54Mbit - it will
negotiate the highest speed it can manage based on signal strength and
hardware support (for the AP and the card) automatically.
I suspect forcing 54Mbit will either not work at all (because the signal isn't
strong enough or your hardware doesn't support it), or it will negotiate a
speed up to 54Mbit (which would result in no functional change).
Locking the transmit rate (and that's what setting the media does) can
be useful but rarely when operating in any configuration but a p2p setup
where the endpoints are fixed. The algorithm used to select a transmit
rate for a frame is very important to getting good performance. John
Bickett's sample algorithm, typically used with ath, is pretty good but
could still be improved.
