I am sure 20060206 would work equally well.
I'd like to know which version started to work worse.

> Andreas, as You says that, I will change from 50 to 20.

Getting wireless to work needs a lot more thinking about
how it actually works (compared to simplicity of wired net).

Think about retries: if you had just one tx retry, you've spend
enough time to send that one frame without retries at *half tx rate*!

Thus even 1 retry is bad. It's ok if you get, say, 1 retry per 10 packets.
It's NOT OK if you get them on almost every paskets.

If you need many retries in order to successfully tx a frame,
you definitely will be better off lowering your max tx
rate instead.
