Hello,

I experimented with setting diversity=0 and it seems to help a bit, getting
the transfer rate up to about 220kbps.

I'm afraid I don't know what the correct tx & rx antenna ports might be
or how to find out. I have this right now:

dev.wifi0.rxantenna = 1
dev.wifi0.txantenna = 0

I tried setting both to 0 and then to 1 but it seemed to make no great difference.


Thanks


Bob
