Oh, really. You're right:

| Maximum data length:                    [ 2304 ]
| RTS/CTS handshake threshold:            [ 2347 ]

How does 'collision detection/avoidance' work then? Will
my station just send stuff (and after each packet listen
for a while) until it get's an ACK?

I knew there was more.... ;)
So, how do I enable short preambles on NetBSD? I've only
seen this on Windows boxes so far. And what does this
actually mean? Is the preamble sent at another speed or is
it only shorter?

And while we're at it: What is micro wave oven robustness?
a joke?
