I get ~500kb/s too. It's not far from 400kb/s the other guy
was reporting, so I think he shall know he won't get 200%
increase and shall not waste huge amounts of his time trying
to achieve 'real 11Mbit/s' :)

DLink DWL-520 and 16-slot waveguide antenna on both ends.
This is the least troublesome link in my network.

Other link is WDS one, and right now it makes me all sorts of troubles.
For example, it has a nasty habit of suddenly starting to have huge packet
loss and after an hour or two dying completely, despite reboot watchdog
and other measures.

Another link is 11g experimental one. Very unpleasant experience
of costly, badly supported by manufacturer, buggy hardware with
mediocre RF sensitivity.

What exactly do you want to know?
