I'm no expert in wireless stuff either, but I know a couple of things for sure: - it's a shared medium. Like original ethernet. So, bandwidth is limited, unlike in a switched ethernet, where it depends mostly on the backplane-bandwidth of the switch - whatever you do with your APs/Repeaters - they all share the same spectrum (shared medium, see above) Who sold them on this "wireless everything stuff"?

But wireless is not meant to shuffle around big amounts of data. At least, last time I looked. Maybe it has changed with Draft-N - but there are no drivers (yet) for Draft-N in FreeBSD anyway, and it's still a shared-medium. Back when we had 10BaseT, files were also much smaller, nobody was sending around 20 MB PPT presentations and downloading a DVD ISO in 3 hours would have been an out-of-body experience. cheers, Rainer -- Rainer Duffner CISSP, LPI, MCSE rainer@ultra-secure.de
