I am gonna guess your issue is timing. that is the same as davids suggestion? karlnet software is supposed to fix this problem... how do you bring this setting down? this is the rtc setting? or is this in the nics on the PC's at both ends? I'm interested to know: are there any other wireless clients connecting to either side of this link? what happens if you run a continuous ping test back and forth from one side to the other? how do the times look? do the logs on either side show anything? also: which firmware version are you running on your DWL900ap+? I've had troubles w/ everything except the january release (2.5). have you tried pulling down the speed to 1 or 2 megs only on both sides? please disclose everything you have going on:
RTS/CTS settings log findings firmware version other clients? speed settings. ping test results how does the link perform? does it start treansferring fine and slow down or is it slow to start transferring and doesn't improve from there? since you're on a budget, I would find a USB or internal wireless card you can connect to one of the antenna's and try and get a little bit of a closer look at how things are working.
