If you're lucky, perhaps a bit more than half of the theoretical speed.

I'd say it's a bit low.  I've seem my maximum sustained throughput at

~22Mb/s, but it usually operates at ~19Mb/s--and I imagine this might

be a bit higher if I didn't use WEP.  I use ral for hostap purposes

and the relevant portion of my current hardware is:
ral0 at cardbus1 dev 0 function 0: irq 10, address 00:14:a5:33:31:c7

ral0: MAC/BBP RT2661B, RF RT2529 (MIMO XR)

I doubt you will ever see true 54Mb/s using 802.11g or 802.11a under any OS.

I can't say much outside of making certain the channel you're using is

not being used by someone else.
